Globally, essential oils (EOs) have been established in the spotlight because of their adaptability and the growing interest of consumers. Citations indeed represent the most significant contributions made in a specific field. With this concern, we performed a bibliometric analysis to describe the 100 most cited articles about plant-derived EOs. The relevant information was retrieved from the Scopus database and scrutinized manually. The selected data was then analyzed and visualized through Microsoft Excel, Bibliometrix and VOSviewer software. A total of 100 documents were reviewed from a total of 48,998 publications. The citation counts of these articles ranged from 541 to 6482. These articles were published in 57 journals among which Phytotherapy Research, Food Chemistry and Journal of Agricultural and Food Chemistry were the most productive journals in terms of number of publications. In the case of contribution of countries and institutions, the USA (n = 12), and Agriculture University of Athens (n = 5) ranked first. The statistical analysis revealed a moderate positive correlation (R2 = 0.5137) between the publication year and number. This analysis revealed critical themes, including the biological potential of EOs and their wide-ranging applications in aromatherapy, edible coatings, and food preservation – areas that were consistently highlighted in the leading cited studies. Overall, this study delineates the developments, research dynamics, and emerging trends in EO research, providing a significant reference for future studies.
在全球范围内,精油(EOs)因其适应性和消费者日益增长的兴趣而成为人们关注的焦点。引文确实代表了在某一特定领域所作的最重要的贡献。考虑到这一点,我们进行了文献计量分析,描述了100篇被引用最多的关于植物源性EOs的文章。相关信息是从Scopus数据库中检索出来的,并进行了手动审查。然后通过Microsoft Excel、Bibliometrix和VOSviewer软件对所选数据进行分析和可视化。共审查了48 998份出版物中的100份文件。这些文章的引用数从541到6482不等。这些文章发表在57种期刊上,其中以《植物疗法研究》、《食品化学》和《农业与食品化学杂志》发表数量最多。在国家和机构的贡献方面,美国(n = 12)和雅典农业大学(n = 5)排名第一。统计分析显示出版年份与出版数量之间存在中度正相关(R2 = 0.5137)。这一分析揭示了关键的主题,包括EOs的生物学潜力及其在芳香疗法、食用涂层和食品保鲜方面的广泛应用——这些领域在主要被引用的研究中一直得到强调。总体而言,本研究描述了生态环境研究的发展、研究动态和新兴趋势,为未来的研究提供了重要的参考。

Background

Stroke remains a leading cause of death and disability, with limited access to costly rehabilitation, especially in developing regions. Sesame (Sesamum indicum), known for its health benefits, shows promise as a neuroprotective agent. This systematic review evaluates current evidence on its potential in stroke treatment and recovery in animal models (In vivo).

Method

The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). A comprehensive search of PubMed and Google Scholar identified original research on the effects of sesame on stroke and related disorders. Studies were screened in stages, and their quality was evaluated using Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) risk of bias tool.

Results

19 studies were included (18 from Asia, 1 from Africa). Sesame derivatives especially sesamin and sesamol demonstrated strong, multi-targeted neuroprotection in stroke models by reducing infarct volume, brain edema, oxidative stress, inflammation, and neuronal damage, while improving neurological recovery. Mechanisms involve enhancing antioxidant enzymes, lowering oxidative markers, suppressing pro-inflammatory mediators, inhibiting apoptosis, and modulating key pathways like (PI3K/AKT, MAPK/ERK, Notch1/NLRP3). Advanced formulations such as sesamol-loaded nanocarriers and the sesamin derivative BBD further enhanced efficacy. Overall, the evidence supports sesame compounds as potent neuroprotective agents against cerebral ischemia.

Conclusion

Overall, sesame shows potential as a therapeutic agent for stroke through its antioxidant, anti-inflammatory, anti-apoptotic, and anti-edematous actions. These effects highlight its potential as a natural, supportive treatment for stroke.
中风仍然是导致死亡和残疾的主要原因,特别是在发展中地区,获得昂贵的康复服务的机会有限。芝麻(Sesamum indicum)以其健康益处而闻名,有望成为一种神经保护剂。本系统综述评估了其在动物模型(体内)中风治疗和恢复方面的潜力。方法按照系统评价和荟萃分析指南的首选报告项目(PRISMA)进行综述。对PubMed和b谷歌Scholar的全面搜索确定了芝麻对中风和相关疾病影响的原始研究。分阶段筛选研究,并使用实验动物实验系统评价中心(sycle)偏倚风险工具对其质量进行评估。结果共纳入19项研究(18项来自亚洲,1项来自非洲)。芝麻衍生物,特别是芝麻素和芝麻醇,通过减少梗死体积、脑水肿、氧化应激、炎症和神经元损伤,同时改善神经系统恢复,在脑卒中模型中显示出强大的多靶点神经保护作用。其机制包括增强抗氧化酶、降低氧化标志物、抑制促炎介质、抑制细胞凋亡和调节关键通路(PI3K/AKT、MAPK/ERK、Notch1/NLRP3)。先进的配方,如芝麻素负载的纳米载体和芝麻素衍生物BBD进一步提高了疗效。总的来说,证据支持芝麻化合物作为脑缺血有效的神经保护剂。结论:芝麻具有抗氧化、抗炎、抗细胞凋亡、抗水肿等作用,具有治疗脑卒中的潜力。这些效果突出了它作为一种自然的、支持性的中风治疗方法的潜力。

Phospholipids (PLs) are crucial membrane components and interact with membrane proteins and cellular receptors to mediate signal transduction and influence metabolic processes. Dietary phospholipids from natural origin, such as those from soybean, egg yolk, krill, squid, and others, are increasingly gaining scientific attention due to growing evidence of their health-enhancing potential. Notably, PLs having long-chain omega-3 polyunsaturated fatty acids (PUFA), especially docosahexaenoic acid (DHA)-containing PLs, have been shown to alleviate experimentally induced conditions such as neurological and metabolic disorders, including liver, kidney, and intestinal damage, heat/UV-radiation-induced stress, and aging. In elderly humans with depression and animal models of neurodegenerative disorders, PLs are reported to alleviate depression and anxiety and improve cognitive abilities. This review discusses the preparation and mechanisms of health promotion by PLs as reported in the scientific literature, mainly within the last two decades. Inhibition of inflammation, oxidative stress, apoptosis, and fat accumulation in tissues and prevention of gut mucosa dysbiosis were among the significant modes of action of PLs. Despite the interesting results reported from in vitro and in vivo studies, there is a lack of consensus on the quantity of PLs to be added to the diet or ingested for optimal health. More clinical studies are needed to clarify the benefits of dietary PLs in humans since most of the recent studies were conducted in rodents.
磷脂(PLs)是重要的膜成分,与膜蛋白和细胞受体相互作用,介导信号转导并影响代谢过程。来自天然来源的膳食磷脂,如来自大豆、蛋黄、磷虾、鱿鱼等的膳食磷脂,由于越来越多的证据表明它们具有促进健康的潜力,正日益受到科学的关注。值得注意的是,含有长链omega-3多不饱和脂肪酸(PUFA)的PLs,特别是含有二十二碳六烯酸(DHA)的PLs,已被证明可以缓解实验诱导的疾病,如神经和代谢紊乱,包括肝、肾和肠道损伤,热/紫外线辐射诱导的应激和衰老。在老年抑郁症患者和神经退行性疾病的动物模型中,据报道,PLs可以缓解抑郁和焦虑,提高认知能力。这篇综述讨论了在科学文献中报道的PLs的制备和促进健康的机制,主要是在最近二十年。PLs的重要作用模式包括抑制炎症、氧化应激、细胞凋亡和组织脂肪积累,以及预防肠道黏膜失调。尽管体外和体内研究报告了有趣的结果,但对于在饮食中添加或摄入多少PLs才能达到最佳健康状态,目前还缺乏共识。由于最近的大多数研究都是在啮齿动物中进行的,因此需要更多的临床研究来阐明膳食中PLs对人类的益处。

Breast cancer remains a major global health challenge requiring novel, safe, and effective therapeutic agents. Trigonelline (1-Methylpyridinium-3-carboxylate), a naturally occurring bioactive compound, has gained growing attention for its potential anticancer properties. In this study, we systematically investigated the molecular characteristics and pharmacological profile of trigonelline using a suite of integrated computational methods, including density functional theory (DFT), molecular docking, and pharmacokinetic (ADMET) assessments. Trigonelline’s geometry was optimized at the B3LYP/6–311 + +G (d, p) level, and quantum descriptors such as HOMO-LUMO gap, molecular electrostatic potential, and Mulliken charge distribution were evaluated to elucidate its stability and reactive behavior. Docking analyses against breast cancer-relevant targets (AKT1, BCL2, BRCA1, Caspase6, GSK3β, PARP1) demonstrated favorable binding, with the strongest affinity observed for BCL2 (-6.3 kcal/mol), highlighting its potential modulatory activity. Pharmacokinetic evaluation through ADMET profiling and BOILED-Egg modeling indicated good gastrointestinal absorption and oral bioavailability, alongside minimal toxicity concerns with no predicted hERG inhibition. Overall, these integrative computational findings underscore trigonelline’s potential as a multitarget anticancer candidate and support its advancement to experimental validation in breast cancer research.
乳腺癌仍然是一个主要的全球健康挑战,需要新颖、安全、有效的治疗药物。Trigonelline (1-Methylpyridinium-3-carboxylate)是一种天然存在的生物活性化合物,因其潜在的抗癌特性而受到越来越多的关注。在这项研究中,我们系统地研究了葫芦巴碱的分子特征和药理学特征,使用了一套集成的计算方法,包括密度泛函数理论(DFT)、分子对接和药代动力学(ADMET)评估。在B3LYP/ 6-311 + +G (d, p)水平上优化了Trigonelline的几何结构,并评估了HOMO-LUMO间隙、分子静电势和Mulliken电荷分布等量子描述子来阐明其稳定性和反应行为。与乳腺癌相关靶点(AKT1, BCL2, BRCA1, Caspase6, GSK3β, PARP1)的对接分析显示出良好的结合,与BCL2的亲和力最强(-6.3 kcal/mol),突出了其潜在的调节活性。通过ADMET分析和煮蛋模型进行的药代动力学评估表明,良好的胃肠道吸收和口服生物利用度,以及最小的毒性问题,没有预测的hERG抑制。总的来说,这些综合计算结果强调了葫芦巴碱作为多靶点抗癌候选药物的潜力,并支持其在乳腺癌研究中的实验验证。

Evidence suggests that citrus flavonoids activate nuclear factor erythroid 2-related factor 2 (Nrf2) that regulates cellular defense against oxidative damage. The effects of citrus flavonoids on the homologous transcription factor skinhead-1 (SKN-1) in the nematode Caenorhabditis elegans are insufficiently studied. Here, we investigated the molecular mechanisms behind the biological activity of a biotransformed citrus extract (FermCAE) and related flavonoids in THP-1 macrophages and in C. elegans. FermCAE upregulated the expression of the Nrf2 target genes heme oxygenase 1 (HMOX1) and NAD(P)H-quinone oxidoreductase 1 (NQO1) in THP-1 macrophages. The formation of excessive reactive oxygen species (ROS) was reduced in stressed cells and nematodes. Transcriptome analysis further indicated that FermCAE modulates stress-response pathways in C. elegans, particularly mitochondrial energy metabolism, nucleotide biosynthesis and ribosome biosynthesis, correlating with improved worm motility and reduced ROS levels. Notably, FermCAE could counteract the paraquat-induced reduction in worm motility in wild-type worms but not in SKN-1 loss-of-function mutants. An elevated GCS-1P::GFP signal in transgenic nematodes further confirmed SKN-1 involvement. These findings suggest that FermCAE protects against oxidative stress by inducing Nrf2/SKN-1 and modulating energy and metabolic pathways to enhance stress resilience.
有证据表明,柑橘类黄酮激活核因子红系2相关因子2 (Nrf2),调节细胞防御氧化损伤。柑橘类黄酮对秀丽隐杆线虫同源转录因子skinhead-1 (SKN-1)的影响研究尚不充分。在这里,我们研究了生物转化柑橘提取物(FermCAE)和相关黄酮类化合物在THP-1巨噬细胞和秀丽隐杆线虫中生物活性的分子机制。FermCAE上调THP-1巨噬细胞中Nrf2靶基因血红素加氧酶1 (HMOX1)和NAD(P) h -醌氧化还原酶1 (NQO1)的表达。过度活性氧(ROS)的形成在应激细胞和线虫中减少。转录组分析进一步表明,FermCAE调节秀丽隐杆线虫的应激反应途径,特别是线粒体能量代谢、核苷酸生物合成和核糖体生物合成,与蠕虫运动能力改善和ROS水平降低相关。值得注意的是,FermCAE可以抵消百草枯引起的野生型蠕虫运动减少,但在SKN-1功能丧失突变体中不起作用。转基因线虫中GCS-1P::GFP信号的升高进一步证实了SKN-1的参与。这些研究结果表明,FermCAE通过诱导Nrf2/SKN-1和调节能量和代谢途径来增强应激恢复能力,从而防止氧化应激。

Diabetic nephropathy (DN), a major contributor to end-stage renal disease, demands therapeutic approaches that can address its complex and multi-pathway progression. This study evaluates the synergistic renoprotective potential of Gallic Acid and berberine hydrochloride using a multi-target in-silico strategy aimed at providing a more comprehensive intervention against DN. Molecular docking revealed strong interactions of both compounds with several DN-related proteins, including human pancreatic alpha-amylase (1B2Y), GSK-3β (1UV5), RXR-α/PPAR-γ (1FM6), DPP-IV (3BJM), ERK2 (4IZ5), PPAR-γ (5U5L), maltase-glucoamylase (2QMJ), GFPT1 (2V4M), insulin receptor kinase (1GAG), 11β-HSD1 (3CH6), and AKT1 (3O96). Berberine HCl showed strong affinity for TGF-β (-11.4 kcal/mol) and PPAR-γ (-8.5 kcal/mol), suggesting effects on fibrotic modulation and improved insulin response. Gallic Acid demonstrated considerable binding to NF-κB (-9.0 kcal/mol) and aldose reductase (-6.6 kcal/mol), indicating its potential to reduce inflammatory activity and oxidative stress. Together, these findings highlight the ability of the two compounds to influence multiple pathological mechanisms, including inflammation, oxidative injury, fibrotic processes, and glucose dysregulation. Pharmacokinetic evaluation indicated favourable drug-likeness, minimal predicted hepatotoxicity, and compatibility for combined oral delivery.

The genus Hedychium J. Koenig (Zingiberaceae) comprises over 100 accepted species distributed across Madagascar, South China, and Tropical Asia. In Northeast India, these species hold substantial ethnomedicinal value and are traditionally used to manage inflammation, wounds, respiratory and gastrointestinal disorders, and several other ailments. This review provides a comprehensive synthesis of both phytochemical and pharmacological research on Hedychium species, with emphasis on their ethnomedicinal applications in Northeast India and a global overview of their essential oils, bioactive constituents, and experimentally validated biological properties. This review synthesizes findings from 312 published articles retrieved from PubMed, Scopus, ScienceDirect, Web of Science, and Google Scholar (search period: 1980–2024). Of these, 147 studies specifically address ethnomedicinal uses, 128 examine phytochemical or essential-oil composition, and 96 evaluate pharmacological activities. Evidence indicates that species such as H. spicatum, H. coronarium, and H. coccineum exhibit notable anti-inflammatory, antimicrobial, antioxidant, and wound-healing activities. Across the genus, more than 120 phytochemicals have been reported, including essential oils (monoterpenes, sesquiterpenes), flavonoids, diterpenes, diarylheptanoids, and labdane-type diterpenoids. Quantitative analyses reveal that the essential oil content ranges from 0.5 to 2.8 % (w/w), dominated by compounds such as 1,8-cineole (12–38 %), linalool (6–25 %), and characteristic labdane diterpenes. Among all species, H. coronarium, H. spicatum, and H. coccineum are most frequently reported, contributing to 58 % of all pharmacological studies reviewed. Experimental evidence (in vitro and in vivo) demonstrates potent antioxidant (up to 85 % DPPH inhibition), antimicrobial (MIC values ranging 64–512 μg/mL), anti-inflammatory (NO inhibition 40–78 %), and cytotoxic/cancer-related activities (IC₅₀ 5–40 μg/mL in various cancer cell lines). Despite this, only 3 species have undergone preliminary toxicity screening and none have been evaluated in clinical trials. Overall, Hedychium species represent a promising but underexplored source of therapeutic compounds. Critical research gaps remain in phytochemical standardization, mechanistic pharmacology, chronic toxicity assessments, and pharmacokinetics. Future studies integrating ethnobotany with modern biological validation will be essential for advancing Hedychium-derived drug discovery.
姜科姜花属(Hedychium J. Koenig)有100多种,分布在马达加斯加、华南和热带亚洲。在印度东北部,这些物种具有重要的民族医学价值,传统上用于治疗炎症、伤口、呼吸和胃肠道疾病以及其他几种疾病。本文综述了黑草属植物化学和药理研究的综合概况,重点介绍了其在印度东北部的民族医药应用,以及其精油、生物活性成分和实验验证的生物学特性的全球概况。本综述综合了从PubMed、Scopus、ScienceDirect、Web of Science和b谷歌Scholar(检索期:1980-2024)检索的312篇已发表文章的发现。其中,147项研究专门针对民族医药用途,128项研究检查植物化学或精油成分,96项评估药理学活性。有证据表明,spicatum、H. coronarium和H. coccineum等物种具有显著的抗炎、抗菌、抗氧化和伤口愈合活性。在整个属中,超过120种植物化学物质已被报道,包括精油(单萜、倍半萜)、类黄酮、二萜、二烷基庚烷和labdane型二萜。定量分析表明,其精油含量为0.5 ~ 2.8 % (w/w),主要化合物为1,8-桉树脑(12-38 %)、芳樟醇(6-25 %)和特征叶丹二萜。在所有物种中,冠状芽孢杆菌、棘状芽孢杆菌和尾骨芽孢杆菌是最常被报道的,占所有药理学研究的58% %。实验证据(体外和体内)证明了有效的抗氧化(高达85 % DPPH抑制),抗菌(MIC值范围为64-512 μg/mL),抗炎(NO抑制40-78 %)和细胞毒/癌症相关活性(IC₅0 5-40 μg/mL)在各种癌细胞系中。尽管如此,只有3种进行了初步毒性筛选,没有一种在临床试验中进行评估。总的来说,Hedychium代表了一种有前途但尚未开发的治疗化合物来源。在植物化学标准化、机械药理学、慢性毒性评估和药代动力学方面仍存在重大研究空白。将民族植物学与现代生物学验证相结合的未来研究将对推进钕衍生药物的发现至关重要。

Background

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuronal loss driven by oxidative stress, neuroinflammation, and protein misfolding. Natural products like ginger (Zingiber officinale) contain neuroprotective sesquiterpenes that may modulate these processes. This study aimed to evaluate the neuroprotective potential of ginger extract and its key bioactive compounds, α-santalol and β-eudesmol, using integrated computational approaches.

Methods

Ginger extract was profiled using GC-MS and LC-MS to identify major constituents. Network pharmacology tools (STRING, Metascape) were used to identify PD-related targets and construct protein-protein interaction networks. Pharmacokinetic and ADMET properties of α-santalol and β-eudesmol were predicted using SwissADME and pkCSM. Molecular docking was performed against PD-associated targets, including LRRK2, to explore potential binding interactions.

Results

Chemical profiling identified major bioactive compounds, including sesquiterpenes like α-santalol and β-eudesmol, with significant neuroprotective properties. Pharmacokinetic analysis revealed favorable BBB permeability, intestinal absorption, and low toxicity. Molecular docking demonstrated strong interactions with PD-related targets, particularly LRRK2, with binding energy values indicating effective target engagement. Pathway enrichment analysis highlighted the involvement of key pathways including NF-κB and Nrf2/ARE in mitigating oxidative stress and neuroinflammation. Biomolecule-target-pathway (B-T-P) networks confirmed the therapeutic relevance of the identified compounds.

Conclusion

Using a fully computational framework, this study identifies α-santalol and β-eudesmol as promising natural molecules with potential relevance to PD-associated pathways. These results are hypothesis-generating, and future biological validation through neuronal survival assays, oxidative-stress and inflammation models, and LRRK2-related functional studies is warranted.
帕金森氏病(PD)是一种进行性神经退行性疾病,其特征是氧化应激、神经炎症和蛋白质错误折叠导致多巴胺能神经元丧失。天然产品如生姜(Zingiber officinale)含有神经保护倍半萜,可以调节这些过程。本研究旨在利用综合计算方法评价生姜提取物及其主要生物活性物质α-桑他洛尔和β-苦艾草酚的神经保护作用。方法采用GC-MS和LC-MS对生姜提取物进行分析,鉴定主要成分。使用网络药理学工具(STRING, metscape)鉴定pd相关靶点并构建蛋白-蛋白相互作用网络。采用SwissADME和pkCSM预测α-桑他洛尔和β-苦参酚的药代动力学和ADMET性质。针对pd相关靶点(包括LRRK2)进行分子对接,以探索潜在的结合相互作用。结果化学分析鉴定出主要的生物活性成分,包括α-桑他罗和β-苦楝酚等倍半萜,具有显著的神经保护作用。药代动力学分析显示良好的血脑屏障通透性,肠道吸收和低毒性。分子对接显示与pd相关靶标,特别是LRRK2有很强的相互作用,结合能值表明有效的靶标结合。通路富集分析强调了NF-κB和Nrf2/ARE等关键通路在减轻氧化应激和神经炎症中的作用。生物分子-靶标-途径(B-T-P)网络证实了所鉴定化合物的治疗相关性。本研究通过一个完整的计算框架,确定α-桑他洛尔和β-桉树酚是有潜力的天然分子,可能与pd相关通路相关。这些结果是假设生成的,未来通过神经元存活分析、氧化应激和炎症模型以及lrrk2相关功能研究进行生物学验证是有必要的。

Purpose

This study aimed to investigate extract mixture of Hibiscus sabdariffa and Citrus paradisi on glucose-induced cataract and glomerulopathy.

Methodology

Hibiscus sabdariffa (HPE) and Citrus paradisi (CPE) samples were collected from local farmers in Bauchi and Plateau States. The samples were air-dried and aqueous-extracted. The extracts obtained were screened for antioxidant molecules (phenolic, carotenoids, vitamin A, C and E) before re-extracted for anthocyanins from HPE and naringin from CPE, and tested for anti-cataractogenic and anti-glomerulopathic activities alone and in combination on rats' lens and glomeruli exposed to high glucose solution. Malondialdehyde and antioxidant enzymes were assayed spectrophotometrically while the morphology of the lens was analyzed microscopically.

Results

The results revealed that extracts of HPE and CPE are high in antioxidants such as phenolics, carotenoids, and vitamins A, C, and E. Lens exposed to high glucose developed cataracts, and treatment with extracts of HPE and CPE alleviated cataracts by reducing oxidative stress and preventing lens opacity. Treatment of glomeruli exposed to high glucose with the mixed extracts (HPE and CPE) enhanced its glucose absorption at 6.07 ± 1.31 mM compared to 1.87 ± 0.62 mM (negative control), antioxidant enzyme activities: CAT (µmol H₂O₂/min) 8.65 ± 0.43 against negative control (3.67 ± 0.32), SOD (U/mL) 14.75 ± 0.84 against negative control (6.12 ± 0.54), Peroxidase (μM tetraguaiacol/min) 11.89 ± 0.60 against negative control; 5.28 ± 0.48 and lower malondialdehyde (µM/L) at 3.97 ± 0.24 against negative control; 9.73 ± 0.65.

Conclusion

The study concluded that the efficacy of HPE and CPE extracts in preventing cataracts and glomerulopathy may be augmented through their combination.

Essential oils have shown considerable promise in combating antimicrobial resistance, due to their complex multicomponent composition. However, their clinical application is limited by high volatility and susceptibility to degradation under stressors such as light and heat. Nanoemulsion formulation offer a potential strategy to enhance the stability and efficacy of essential oils. This study investigated the emulsification of essential oils extracted from the leaves and stembark of Cleistopholis patens and Vitex simplicifolia, as well as the antimicrobial activity of the resulting nanoemulsions. V. simplicifolia essential oil yielded the highest extraction percentage (0.135 %), followed by C. patens (0.050 %). Gas chromatography-mass spectrometry analysis identified 19 and 20 constituents in the leaf and stembark oils of C. patens, and 10 and 7 in those of V. simplicifolia, respectively. Major components included β-eudesmol (16.06 %) and β-cubebene (10.58 %) in C. patens, and hexadecane (32.26 %) and 1-octen-3-ol (44.48 %) in V. simplicifolia. Nanoemulsions were formulated using surfactant-to-oil ratios of 7:3, 8:2, and 9:1. All formulations exhibited enhanced antimicrobial activity compared to the pure essential oils, with the 9:1 nanoemulsion demonstrating the lowest minimum inhibitory concentrations (MICs: 3.9–8.7 mg/mL). Characterization of the 9:1 emulsion revealed nanometric particle sizes (51.8–188.2 nm), low polydispersity indices (0.206–0.359), and favorable zeta potentials, indicating high stability and monodispersity. Additionally, both the essential oils and the 9:1 nanoemulsions significantly enhanced the antimicrobial efficacy of ciprofloxacin, with modulation factors ranging from 0.06 to 16. These findings support the potential of nanoemulsified essential oils as stable, effective antimicrobial agents and adjuvants in antibiotic therapy.
精油由于其复杂的多组分组成,在对抗抗菌素耐药性方面显示出相当大的希望。然而,它们的临床应用受到高挥发性和在光和热等应激因素下易降解的限制。纳米乳液配方为提高精油的稳定性和功效提供了一种潜在的策略。本研究研究了从鸢尾和牡荆叶和叶冠中提取的精油的乳化作用,以及所得纳米乳液的抑菌活性。单叶挥发油提取率最高(0.135 %),其次是白花挥发油(0.050 %)。气相色谱-质谱联用分析分别鉴定出19种、20种、10种、7种化学成分。其中主要成分为β-苦参酚(16.06 %)和β-立方苯(10.58 %),单叶草中主要成分为十六烷(32.26 %)和1-辛烯-3-醇(44.48 %)。纳米乳液的配方采用表面活性剂与油的比例分别为7:3、8:2和9:1。与纯精油相比,所有配方均表现出增强的抗菌活性,其中9:1纳米乳液的最低抑菌浓度最低(mic: 3.9-8.7 mg/mL)。对9:1乳液的表征表明,其粒径为纳米级(51.8-188.2 nm),多分散性指数(0.206-0.359)较低,zeta电位良好,具有较高的稳定性和单分散性。此外,精油和9:1纳米乳均显著增强环丙沙星的抗菌效果,调节因子在0.06 ~ 16之间。这些发现支持纳米乳化精油在抗生素治疗中作为稳定、有效的抗菌剂和佐剂的潜力。

However, their clinical application is limited by high volatility and susceptibility to degradation under stressors such as light and heat. Nanoemulsion formulation offer a potential strategy to enhance the stability and efficacy of essential oils. This study investigated the emulsification of essential oils extracted from the leaves and stembark of <em>Cleistopholis patens</em> and <em>Vitex simplicifolia</em>, as well as the antimicrobial activity of the resulting nanoemulsions. <em>V. simplicifolia</em> essential oil yielded the highest extraction percentage (0.135 %), followed by <em>C. patens</em> (0.050 %). Gas chromatography-mass spectrometry analysis identified 19 and 20 constituents in the leaf and stembark oils of <em>C. patens</em>, and 10 and 7 in those of <em>V. simplicifolia</em>, respectively. Major components included β-eudesmol (16.06 %) and β-cubebene (10.58 %) in <em>C. patens</em>, and hexadecane (32.26 %) and 1-octen-3-ol (44.48 %) in <em>V. simplicifolia</em>. Nanoemulsions were formulated using surfactant-to-oil ratios of 7:3, 8:2, and 9:1. All formulations exhibited enhanced antimicrobial activity compared to the pure essential oils, with the 9:1 nanoemulsion demonstrating the lowest minimum inhibitory concentrations (MICs: 3.9–8.7 mg/mL). Characterization of the 9:1 emulsion revealed nanometric particle sizes (51.8–188.2 nm), low polydispersity indices (0.206–0.359), and favorable zeta potentials, indicating high stability and monodispersity. Additionally, both the essential oils and the 9:1 nanoemulsions significantly enhanced the antimicrobial efficacy of ciprofloxacin, with modulation factors ranging from 0.06 to 16. These findings support the potential of nanoemulsified essential oils as stable, effective antimicrobial agents and adjuvants in antibiotic therapy.</div></div>","PeriodicalId":101014,"journal":{"name":"Pharmacological Research - Natural Products","volume":"10 ","pages":"Article 100555"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
