A laboratory experiment was conducted on French beans (phaseolus vulgaris L.) to investigate the effect of organic and inorganic seed treatments on seed health. The seeds of French bean were subjected to different seed treatments viz., T0: Control (untreated), T1: Neem leaf powder @5g/kg of seed, T2: neem oil @5ml/kg of seed, T3: Castor oil @5ml/kg of seed, T4: karanj oil @5ml/kg of seed, T5: vekhand powder @10g/kg of seed, T6: Termuric powder @5g/kg of seed, T7: Citronella oil @5ml/kg of seed, T8: Ash @5g/kg of seeds, T9: Deltamethrin @0.04ml/kg of seed. Seed health was tested for different parameters viz., pulse beetle infestation, seed weight loss, egg-laying, adult emergence, percent mortality, dead insects and live insects. The bio-efficacy test was undertaken to find out the effect of chemicals and different botanicals against pulse beetle in French bean seed. Results revealed that seeds treated with Deltamethrin @0.04ml/kg of seed significantly recorded the lowest pulse beetle infestation (1.33%), lower number of egg-laying (11.00), lowest number of adult emergence (1.67), lowest seed weight loss (4.67%), highest mortality (87.8%), higher dead insect (15.00) and lower live insect (5.00) at the end of storage period. Among the botanicals, seed treated with neem oil @5 ml/kg of seed showed higher seed quality and health parameters. From the present investigation, the seed treated with organic and inorganic components protected the seed health while, the control seed deteriorated at the end of the storage period.
通过室内试验,研究了有机和无机种子处理对豆荚种子健康的影响。对法国豆种子进行不同的种子处理,即T0:对照(未处理),T1:楝叶粉@5g/kg种子,T2:楝油@5ml/kg种子,T3:蓖麻油@5ml/kg种子,T4: karanj油@5ml/kg种子,T5: vekhand粉@10g/kg种子,T6: Termuric粉@5g/kg种子,T7:香茅油@5ml/kg种子,T8:灰分@5g/kg种子,T9:溴氰菊酯@0.04ml/kg种子。对种子健康进行了不同参数的测试,即脉冲甲虫侵染、种子失重、产卵、成虫羽化、死亡率、死虫率和活虫率。采用生物药效试验研究了化学药剂和不同植物制剂对豆荚中脉冲虫的防治效果。结果表明,0.04ml/kg溴氰菊酯处理的种子在贮藏期末的虫患率最低(1.33%),产卵率最低(11.00),成虫出羽率最低(1.67),失重率最低(4.67%),死亡率最高(87.8%),死虫率较高(15.00),活虫率较低(5.00)。其中,@5 ml/kg印楝油处理的种子质量和健康指标较高。从目前的调查结果来看,有机和无机组分处理的种子在贮藏期结束时保持了种子的健康,而对照种子在贮藏期结束时变质。

Background: Propolis has been traditionally used in many countries for management of various health conditions and many previous studies have shown that it has many biological activities, including antimicrobial activity and cytotoxicity. However, not much has been studied with regard to Tanzanian propolis; hence this study reports biological activity of propolis collected from 8 regions of Tanzania. Objectives: The purpose of this study was to evaluate the antimicrobial activity and potential cytotoxicity of propolis samples collected from various regions of Tanzania. Metet hods: Ethanolic extracts of 28 propolis samples collected from 8 regions in Tanzania were evaluated for antimicrobial activity against Gram +ve bacteria, Gram -ve bacteria and fungi, using the broth microdilution method, through which minimum inhibitory concentrations were determined. Brine shrimp lethality test was done using Artemia salina nauplii, as a preliminary indication of potential anticancer activity. Results: Out of 28 tested propolis samples, 21 exhibited antimicrobial activity on one or more microorganisms at the tested concentrations, with MICs of 1.25 – 5.0 mg/ml. Fourteen out of 28 samples were found to be toxic on brine shrimps, with a sample from Singida region being the most toxic. Conclusion: Propolis samples from various regions of Tanzania demonstrated antimicrobial activity on some microorganisms, indicating that they are a potential source of antimicrobial agents. Some samples also exhibited brine shrimp toxicity; implying that they may also be toxic on cancer cells and thus, may be a potential source of anticancer agents. They may also be a source of compounds with other biological activities.
背景:蜂胶传统上在许多国家用于各种健康状况的管理,许多先前的研究表明,蜂胶具有许多生物活性,包括抗菌活性和细胞毒性。然而,关于坦桑尼亚蜂胶的研究并不多;因此,本研究报告了从坦桑尼亚8个地区收集的蜂胶的生物活性。目的:本研究的目的是评估从坦桑尼亚不同地区采集的蜂胶样品的抗菌活性和潜在的细胞毒性。方法:采用微量肉汤稀释法,对坦桑尼亚8个地区28份蜂胶乙醇提取物对革兰氏+ve菌、革兰氏-ve菌和真菌的抑菌活性进行评价,确定最低抑菌浓度。以盐渍蒿(Artemia salina nauplii)为原料进行了盐水对虾致死试验,初步表明其具有潜在的抗癌活性。结果:在28个测试的蜂胶样品中,21个在测试浓度下对一种或多种微生物具有抗菌活性,MICs为1.25 - 5.0 mg/ml。28个样本中有14个对卤水虾有毒,其中来自Singida地区的样本毒性最大。结论:来自坦桑尼亚不同地区的蜂胶样品显示出对某些微生物的抗菌活性,表明它们是抗菌药物的潜在来源。部分样品还表现出卤虾毒性;这意味着它们也可能对癌细胞有毒,因此可能是抗癌剂的潜在来源。它们也可能是具有其他生物活性的化合物的来源。

Dillenia pentagyna often known as ‘Karmal’ is a member of Dilleniaceae. Different parts of the plant have been used by tribal communities to treat a broad spectrum of ailments. The plant reports the presence of some vital therapeutic compounds such as botulin, botulinic acid, botulinic acid, morolic acid, lupeol, diploic acid, etc. Some of the major pharmaceutical properties of the plant are anticancerous, anti-fungal, anti-bacterial, and anti-diabetic. This plant has been recently classified as a critically endangered species in Madhya Pradesh state. Low germination rates are one of the major factors of being a critically endangered species. Despite being a potent curative plant species, it is yet to be fully explored. The objective of the present review to highlight the phytochemical investigations and pharmacology applications for several purposes like anti-diabetic, anti-cancerous, anti-microbial, antioxidant, etc of this plant species. In future studies, this knowledge can be applied to the safe and evidence-based use of traditional Indian medicinal plants in global Phyto pharmacotherapy and to the discovery of novel leads for the development of herbal formulations.

Essential oils, which are the plant derived secondary metabolites have been reported for various traditional medicinal applications. Amongst them, lemongrass oil (LGO) derived from Cymbopogon spp. as well as its major constituent citral possess a myriad of therapeutic potentials. The present study has been undertaken to study the adverse effects of LGO and citral on acute oral exposure to Sprague Dawley rats to establish the preliminary safety of these compounds prior to their efficacy evaluation against fatty liver disease. The toxicity study was conducted as per OECD guidelines No. 420. The LGO and citral were solubilized in 1% tween 80 and administered orally in a sequential manner in one animal at 2000 mg/kg (sighting study) followed by four animals (main study). The animals were then monitored for any clinical abnormalities or mortality and body weight gain during the observational period of 14- days, after which the animals were sacrificed and examined for abnormal lesions. LGO was further subjected to gas chromatography-mass spectrometry (GC-MS) analysis to characterize its chemical constituents, which revealed alpha and beta citral as the two major constituents. The rats treated with LGO and citral survived throughout the study period and didn’t exhibit any clinical abnormalities. Moreover, body weight gain was comparable to the vehicle treated rats and necropsy revealed no pathological alterations. Thus, the present study indicated LGO and citral as safe compounds with an LD50 greater than 2000 mg/kg and could be labelled as category 5/unclassified in hazard category of Globally harmonized system for classification of chemicals.
精油是植物衍生的次生代谢产物,已被报道用于各种传统医学应用。其中,从香茅属植物中提取的柠檬草精油(LGO)及其主要成分柠檬醛具有无数的治疗潜力。本研究旨在研究LGO和柠檬醛对Sprague Dawley大鼠急性口服暴露的不良影响,在评估其对脂肪肝疾病的疗效之前,确定这些化合物的初步安全性。毒性研究是按照经合组织第420号准则进行的。将LGO和柠檬醛在80年之间以1%的浓度溶解,并在一只动物中按2000 mg/kg顺序口服(观察研究),然后在四只动物中依次口服(主要研究)。然后在14天的观察期内监测动物的任何临床异常或死亡率和体重增加,之后处死动物并检查异常病变。进一步采用气相色谱-质谱联用(GC-MS)对其化学成分进行表征,发现α和β柠檬醛是其主要成分。用LGO和柠檬醛治疗的大鼠在整个研究期间都存活下来,没有出现任何临床异常。此外,体重增加与给药大鼠相当,尸检未发现病理改变。因此,本研究表明,LGO和柠檬醛是安全的化合物,其LD50大于2000 mg/kg,可以在全球化学品统一分类系统中标记为第5类/未分类的危险类别。

Since ancient times, Amalakyadi Gana, a polyherbal formulation of Susruta Samhita (6th century BCE), has been used for the prevention and treatment of numerous gastrointestinal diseases. This formulation consists of fruits of Phyllanthus emblica, Terminalia chebula, Piper longum, and the root of Plumbago zeylanica. The hepatoprotective efficacy of this formulation was evaluated following the acute toxicity study in mice to validate its ayurvedic uses. The hepatoprotective efficacy was assessed using paracetamol-induced hepatotoxicity in Swiss albino mice. Research drug exhibited in normalizing the PCM-dependent rise of serum liver function markers. After administration of the aqueous extract of Amalakyadi Gana, relevant blood biochemical measures showed significant (P < 0.05) hepatoprotective activity in a dosage-dependent manner, especially at the dose of 700 mg/kg orally in mice. When compared to the control group, significant (p < 0.05) histological alterations were also observed in the liver tissues. This formulation exhibited results in normalizing the liver architecture by decreasing necrotic foci along with the normal liver parenchymal structure in the research drug pre-treated groups mainly at the dose of 700 mg/kg, caused due to paracetamol toxicity. The research drug's sustained activity was comparable to that of the silymarin (200 mg/kg, p.o.) reference medicine. This formulation possesses significant hepatoprotective activity without any toxicity in mice.
自古以来,Amalakyadi Gana, Susruta Samhita(公元前6世纪)的一种多草药配方,一直被用于预防和治疗许多胃肠道疾病。该配方由余甘子、chebula Terminalia、Piper longgum和Plumbago zeylanica的根组成。在小鼠急性毒性研究后,对该配方的肝保护功效进行了评估,以验证其阿育吠陀的用途。采用对乙酰氨基酚对瑞士白化病小鼠的肝毒性评价其肝保护作用。研究药物显示出对pcm依赖性血清肝功能指标升高的正常化作用。给药后,相关血液生化指标显示出显著(P < 0.05)的肝保护活性,且呈剂量依赖性,尤其是口服剂量为700 mg/kg时。与对照组相比,肝组织组织学改变显著(p < 0.05)。在研究药物预处理组中,该制剂主要以700 mg/kg剂量处理,由于扑热息痛毒性引起的坏死灶减少,肝脏结构正常化,肝脏实质结构正常。该研究药物的持续活性与水飞蓟素(200 mg/kg, p.o.)参比药相当。该制剂具有显著的保肝活性,对小鼠无任何毒性。

In this current case report, A 54-year-old non-alcoholic, married woman presented with chief complaints of abdominal pain and unbearable pain while passing urine, CT scan revealed an enlarged liver (16.2 cm in size) and a thick-walled cystic lesion measuring (4.3*4.1*6.0 in the right ovary adnexa) on 17th October 2020. The patient started following Uni5 treatment in November 2020 and continued the treatment until she was cured completely. Based on the five elements principle, she was treated for four months with Uni5 cleansing treatment, hot oil fomentation, liver tonic-rich herbs, and probiotics-rich food. Her condition was monitored through a CT scan, and after two months she was relieved from uterine fibroid and liver enlargement. This indicates that there is an association between Gut microbiomes, fatty liver, and polycystic ovarian syndrome. Therefore, a uterine fibroid can be entirely cured through Uni5 treatment.
在本病例报告中,一名54岁非酒精性已婚女性,主诉为腹痛和排尿时难以忍受的疼痛,CT扫描显示肝脏肿大(16.2 cm)和厚壁囊性病变(右卵巢附件4.3*4.1*6.0)。该患者于2020年11月开始接受Uni5治疗,并持续治疗至完全治愈。根据五行原理,对患者进行了为期4个月的Uni5清洁治疗,热油发酵,富肝补益的草药和富含益生菌的食物。她的病情通过CT扫描监测,两个月后,她的子宫肌瘤和肝脏肿大得到缓解。这表明肠道微生物群、脂肪肝和多囊卵巢综合征之间存在关联。因此,子宫肌瘤可以通过Uni5治疗完全治愈。

(+)-(R)-de-O-methyllasiodiplodin (DOML), isolated from the Chinese herbal medicine Ludwigia hyssop folia, has great potential for development in pharmacological research on hepatocellular carcinoma (HCC). In our study, the CCK-8 assay, morphological observation, flow cytometry (also known as Annexin V-FITC/PI double staining), as well as Western blotting were adopted to study the anti-liver cancer activity and mechanisms of DOML on HepG2 and HuH-7 cells. The research exhibited that DOML dose- and time-dependently reduced the cell viability of HCC cells. DOML treatment resulted in changes in cell morphology, such as irregular edges, reduced volume, and decreased adhesion were observed under the microscope. Flow cytometry analysis indicated that apoptosis is the major form of cell death. In addition, blocking autophagy and necroptosis pathways couldn’t alleviate DOML-induced apoptosis. Protein expression levels of Bax, activated Caspase-3 and Caspase-9, and PARP were increased, while Bcl-2 protein levels were reduced by DOML treatment, which suggested that the mitochondrial apoptotic pathway may be involved in DOML-induced cell death. Moreover, the expression of NF-κB and the phosphorylation of Akt and STAT3 decreased with the increase of dosage, suggesting that the apoptotic mechanism might be related to the Akt/NF-κB and STAT3 signaling pathways. All these results indicate that DOML has the potential effects of anti-hepatoma.
(+)-(R)-de- o -methyllasiodiplodin (DOML)从中草药Ludwigia hyssop folia中分离得到,在肝细胞癌(HCC)的药理研究中具有很大的开发潜力。本研究采用CCK-8实验、形态学观察、流式细胞术(又称Annexin V-FITC/PI双染色)、Western blotting等方法研究了DOML对HepG2和HuH-7细胞的抗肝癌活性及其作用机制。研究表明,DOML降低HCC细胞的细胞活力具有剂量和时间依赖性。DOML处理导致细胞形态学改变,显微镜下观察到细胞边缘不规则,体积减小,黏附降低。流式细胞术分析表明,细胞凋亡是细胞死亡的主要形式。此外,阻断自噬和坏死下垂途径不能减轻doml诱导的细胞凋亡。经DOML处理后,Bax、活化Caspase-3、Caspase-9和PARP蛋白表达水平升高,Bcl-2蛋白表达水平降低,提示线粒体凋亡途径可能参与了DOML诱导的细胞死亡。NF-κB表达和Akt、STAT3磷酸化水平均随剂量增加而降低,提示凋亡机制可能与Akt/NF-κB和STAT3信号通路有关。这些结果表明,DOML具有潜在的抗肝癌作用。

Several sex selection methods are available but with varying success rates, availability, and affordability. Vernonia amygdalina has been used by some Kenyan communities for the male child pre-selection at conception but these claims have not been scientifically ascertained. This study aims at evaluating the ability of this herbal plant to pre-select for the male child at conception. The roots of the plant were collected and processed before extraction using methanol. The obtained crude plant extracts were orally administered to Rattus norvegicus rats before and during mating for one week. Crude extracts at doses of 50, 87, and 150mg/kg body weight were used to evaluate the effects of the plant on the sex ratio of pups and factors related to sex ratio. A P value of P<0.05 was set as the limit of significance. The extracts were also subjected to quantitative phytochemical and mineral analysis. The results indicated that treating female rats with the plant extract significantly increased the ratio of male to female pups in all the treatment groups. There was a significant decrease in serum cortisol levels in both male and female rats and an increase in vaginal pH in female rats. The 50 and 87 mg/kg doses caused a significant increase in estrogen levels compared to the untreated group. These results validated the use of the plant by herbalists for the preselection of a male child at conception.
有几种可用的性别选择方法,但成功率、可用性和可负担性各不相同。一些肯尼亚社区在受孕时使用扁桃果来预选男孩,但这些说法尚未得到科学证实。本研究的目的是评估这种植物在受孕时对男孩进行预选的能力。植物的根被收集和处理,然后用甲醇提取。得到的植物粗提取物分别在褐家鼠交配前和交配中口服1周。以50、87和150mg/kg体重的粗提物为剂量,评价该植物对幼鼠性别比的影响及相关因素。以P<0.05为显著性界限。提取物还进行了定量的植物化学和矿物分析。结果表明,各处理组雌性大鼠的雌雄仔比均显著提高。雄性和雌性大鼠的血清皮质醇水平显著下降,雌性大鼠的阴道pH值升高。与未治疗组相比,50和87 mg/kg剂量导致雌激素水平显著增加。这些结果证实了草药医生在受孕时预选男孩时使用这种植物。

Purification of dichloromethane extract from root barks and leaves of Synadenium glaucescens extracts through chromatographic techniques resulted into the isolation of two compounds, namely erythrinacinate C and 1-octacosanol. Chemical structures were established mainly using both one and two dimensional 1H and 13C NMR data and by comparison of the current NMR data with those from literature. Mass spectrophotometry data were used for confirmation through molecular ion peak. Both compounds are known to have been isolated from other plant species but are being reported from this plant species for the first time.
利用层析技术对海合子根皮和叶片的二氯甲烷提取物进行纯化,分离到赤藓酸盐C和1-八烷醇两种化合物。主要利用一维和二维1H和13C核磁共振数据,并将现有核磁共振数据与文献数据进行比较,建立化学结构。用质谱数据通过分子离子峰进行确认。已知这两种化合物均从其他植物中分离得到,但均为首次从该植物中分离得到。
