The nutrient composition of many wild plants remains largely unexplored, despite their historical inclusion in diets, often without awareness of their health benefits. Therefore, this study aimed to elucidate the proximate composition, mineral content, and amino acid profiles of four locally consumed leafy vegetables in Bangladesh: Corchorus olitorius L., Colocasia esculenta (L.) Schott, Piper longum L., and Typhonium trilobatum L. The analysis revealed that these vegetables possess significant amounts of protein, carbohydrates, and energy, with C. esculenta showing notably higher fat content (7.92 mg/g). The mineral analysis indicated that all four vegetables are rich in sodium, potassium, calcium, manganese, iron, and zinc. Notable amount of essential amino acids like lysine (9.93 mg/g), leucine (9.93 mg/g), glycine (14.79 mg/g) and phenylalanine (9.56 mg/g) were found higher in amount in the studied plants, aligning with the WHO-recommended daily dietary requirements (Technical Report Series 935), and demonstrating their potential as sustainable nutritional resources to address global protein deficiencies. All plants also showed considerable amounts of fiber (range from 1.80% - 3.56%), carbohydrates (45.84 - 55.48%), protein (17.57 - 20.43%), and energy (335.48 - 358.94 Kcal/100g), enhancing their utility as functional food ingredients. The study also identified strong correlations between investigated parameters using the Pearson correlation, underscoring the nutritional potential of these vegetables. These findings will enrich the nutritional database of Bangladesh and demonstrate these wild plants' potential as significant sources of macro- and micronutrients, which could encourage their consumption and cultivation.

许多野生植物的营养成分在很大程度上仍未被探索，尽管它们在历史上被纳入饮食，但人们往往没有意识到它们对健康的益处。因此，本研究旨在阐明孟加拉国当地消费的四种叶菜的大致组成，矿物质含量和氨基酸分布：Corchorus olitorius L., Colocasia esculenta （L.）。分析表明，这些蔬菜含有大量的蛋白质、碳水化合物和能量，其中肉芽甘蓝的脂肪含量显著高于其他蔬菜（7.92 mg/g）。矿物质分析表明，这四种蔬菜都富含钠、钾、钙、锰、铁和锌。在所研究的植物中发现大量必需氨基酸，如赖氨酸（9.93毫克/克）、亮氨酸（9.93毫克/克）、甘氨酸（14.79毫克/克）和苯丙氨酸（9.56毫克/克）的含量较高，符合世卫组织推荐的每日膳食需求（技术报告系列935），并显示出它们作为解决全球蛋白质缺乏问题的可持续营养资源的潜力。所有植物还显示出相当数量的纤维（1.80% ~ 3.56%）、碳水化合物（45.84 ~ 55.48%）、蛋白质（17.57 ~ 20.43%）和能量（335.48 ~ 358.94 Kcal/100g），增强了它们作为功能性食品成分的实用性。该研究还利用Pearson相关性确定了所调查参数之间的强相关性，强调了这些蔬菜的营养潜力。这些发现将丰富孟加拉国的营养数据库，并证明这些野生植物作为宏量和微量营养素的重要来源的潜力，这可能鼓励它们的消费和种植。

In Ethiopia, wild edible plants (WEPs) are widely consumed. Despite the extensive usage of WEPs in Ethiopia, there have been few investigations on their nutritional composition.This study aimed to investigate the biochemical composition and antioxidants of the most commonly consumed three WEPs, Amaranthus tortuosus, Landolphia buchananii, and Oncoba spinosa in Soro District, Ethiopia. The proximate, mineral, vitamin C, and oxalate of them were determined using the method by AOAC. Anti-nutrients, total phenolic and flavonoids, and antioxidant capacity of the WEPs using standard spectroscopic methods. The highest crude protein content (38 g/100 g) was observed in Amaranthus tortuosus. Other nutrients on dry basis of crude fat, crude fiber, utilizable carbohydrate, gross energy, calcium, iron and zinc, vitamin C were resulted., including anti-nutrients of phytate, oxalate and tannin. O. spinosa has higher anti-nutrient content. The highest phenolic, flavonoid, and vitamin C in L. buchananii fruit. The L. buchananii extract had a comparable IC50 value with ascorbic acid in scavenging 2,2-diphenyl-1-picrylhydrazyl free radical. At 200 μg/ mL, the highest percentage of DPPH inhibition obtained for ascorbic acid. This study indicated, WEPs had more antioxidants than some common popular crops; it suggests that they can be incorporated to make more nutrient-dense and healthy-balanced diets.

在埃塞俄比亚，野生可食用植物（wep）被广泛食用。尽管wep在埃塞俄比亚广泛使用，但对其营养成分的调查很少。本研究旨在研究埃塞俄比亚索罗地区最常见的三种WEPs， Amaranthus tortuosus， Landolphia buchananii和Oncoba spinosa的生化成分和抗氧化剂。采用AOAC法测定了其中的比邻物、矿物质、维生素C和草酸盐含量。用标准光谱法测定wep的抗营养成分、总酚和总黄酮以及抗氧化能力。粗蛋白质含量最高的是弯苋（Amaranthus tortuosus），为38 g/100 g。其他干性营养成分为粗脂肪、粗纤维、可利用碳水化合物、总能、钙、铁、锌、维生素C。，包括抗营养物质植酸、草酸和单宁。刺花草具有较高的抗营养成分。最高的酚，类黄酮和维生素C的l.b chananii果实。在清除2,2-二苯基-1-苦酰肼自由基方面，其IC50值与抗坏血酸相当。在200 μg/ mL时，抗坏血酸对DPPH的抑制率最高。研究表明，WEPs的抗氧化剂含量高于一些普通常用作物；研究表明，它们可以被纳入营养更丰富、更健康均衡的饮食中。

A novel analytical method was developed for the determination of cadmium in tea samples using a natural deep eutectic solvent-based magnetic nanofluid liquid phase microextraction technique, combined with graphite furnace atomic absorption spectrometry. In this study, cadmium forms a neutral and hydrophobic complex with dithizone, which is subsequently extracted by the magnetic nanofluid prepared through the dispersion of Fe₃O₄ nanoparticles in a natural deep eutectic solvent composed of l-menthol and formic acid. The method demonstrated excellent analytical performance, with limits of detection (LOD) and quantification (LOQ) of 0.0060 and 0.018 ng/L, respectively. The linearity range of the NADES-MNF-LPME–GFAAS method was 0.018 to 0.20 ng L. The concentrations of cadmium in the real samples ranged from 0.08 to 1.05 ng/L in tap water samples and from 0.03 to 0.19 ng/L in tea leaf samples, respectively. Cadmium was successfully quantified in real samples with recoveries of 80–120%. Interference from coexisting ions was also evaluated to ensure method selectivity. Finally, statistical comparison of t-values between the proposed method and both Thailand Reference Material and standard reference materials showed no significant differences at the 95% confidence level (df=2), confirming the method’s reliability and suitability for cadmium contamination assessment in food.

This study aimed to extract and characterize pectin from carambola (Averrhoa carambola) peel using three extraction techniques: conventional acid extraction (CAE), microwave-assisted extraction (MAE), and ultrasound-assisted extraction (UAE). Pectin was extracted using organic citric acid at pH 2, and the study comprehensively evaluated its yield and solubility along with physicochemical properties—equivalent weight (EW), methoxyl (MeO) content, anhydrouronic acid (AUA) content, degree of esterification (DE), ash percentage, and pH—across the three extraction methods. The results revealed that the extraction technique significantly impacted the yield and properties of pectin. Among the methods, MAE produced the highest yield of pectin (22.38 ± 0.32 %), demonstrating its efficiency. Each extraction method offered distinct advantages, influencing both the physicochemical characteristics and solubility behavior of the pectin. Based on the MeO and DE values, all extracted pectins from carambola peel were identified as high-methoxyl pectins, making them suitable for various industrial applications. Additionally, the high AUA content indicated the purity of the extracted pectin. Fourier transform infrared (FTIR) spectroscopy was employed to distinguish the extracted pectin structurally. The spectral analysis identified functional groups within the 1800–800 cm⁻¹ range, confirming the presence of key chemical components associated with pectin’s structure. This study highlights the comparative advantages of MAE and UAE in enhancing pectin yield and purity while preserving its functional properties. These findings underscore the potential of carambola peel-derived pectin for applying in gel formation, stabilization, emulsification, and thickening of food products.

采用常规酸提取（CAE）、微波辅助提取（MAE）和超声辅助提取（UAE）三种提取技术对杨桃果皮中的果胶进行提取和表征。在pH为2的条件下，采用有机柠檬酸提取果胶，综合评价了三种提取方法的产率、溶解度、理化性质——等效质量（EW）、甲氧基（MeO）含量、无水醛酸（AUA）含量、酯化度（DE）、灰分率和pH。结果表明，提取工艺对果胶的收率和性能有显著影响。其中，MAE的果胶得率最高（22.38±0.32%），证明了其效率。每种提取方法都有其独特的优点，影响果胶的物理化学特性和溶解度。根据MeO和DE值，从杨桃果皮中提取的果胶均为高甲氧基果胶，适用于各种工业应用。此外，高AUA含量表明提取的果胶纯度高。利用傅里叶变换红外光谱（FTIR）对提取的果胶进行了结构鉴别。光谱分析确定了1800-800 cm−1范围内的官能团，确认了与果胶结构相关的关键化学成分的存在。本研究强调了MAE和UAE在提高果胶收率和纯度的同时保持果胶功能特性方面的比较优势。这些发现强调了杨桃皮衍生果胶在凝胶形成、稳定、乳化和食品增稠方面的应用潜力。

The digestive fate of neuroactive food compounds remains poorly understood despite growing interest in their role in brain health. This study developed advanced analytical methods to identify neuroprotective and neuro-disrupting compounds in tomatoes before and after digestion and following fecal fermentation. Using in vitro digestion and fermentation models, we characterized compound behavior during digestion. Most compounds were quantified in undigested tomatoes. Digestion revealed diverse outcomes: some compounds transformed (e.g., chlorogenic acids), others produced (e.g., linoleic acid), and several remained stable with potential to reach the colon (e.g., serotonin, rutin). Notably, neuro-disrupting compounds like bisphenols remained largely unaltered and bioaccessible in the colon. Fecal fermentation further showed dynamic changes, with some compounds decreasing (e.g., rutin) and others increasing (e.g., quercetin). These findings provide both methodological advances and mechanistic insights into neuroactive compound behavior during digestion, informing future research on gut-mediated dietary effects in the context of neurodegenerative disease prevention.

尽管人们对神经活性食物化合物在大脑健康中的作用越来越感兴趣，但它们的消化命运仍然知之甚少。本研究开发了先进的分析方法来鉴定西红柿在消化前后和粪便发酵前后的神经保护和神经破坏化合物。利用体外消化和发酵模型，我们表征了化合物在消化过程中的行为。大多数化合物在未消化的番茄中被量化。消化显示出不同的结果：一些化合物转化（如绿原酸），另一些产生（如亚油酸），还有一些保持稳定并有可能到达结肠（如血清素、芦丁）。值得注意的是，双酚类神经干扰化合物在结肠中基本保持不变，并具有生物可及性。粪便发酵进一步表现出动态变化，一些化合物（如芦丁）减少，另一些化合物（如槲皮素）增加。这些发现为消化过程中神经活性化合物的行为提供了方法上的进步和机制上的见解，为未来研究肠道介导的饮食对神经退行性疾病预防的影响提供了信息。

Costa Rican guava (Psidium friedrichsthalianum [O. Berg] Nied) press cake (GPC) is an underutilized by-product of juice and pulp production with potential as a source of functional compounds. This study aimed to characterize the nutritional composition, polyphenolic profile, and antioxidant capacity of GPC and evaluate the impact of hot-air drying (AD) and freeze-drying (FD) on its bioactive components. Proximate analysis revealed a high dietary fiber content (70.00±1.50 g/100 g), moderate protein levels (5.74±0.04 g/100 g), and low-fat content (0.15±0.04 g/100 g). Organic acid and vitamin profiling showed higher retention in FD samples, with vitamin C concentrations exceeding 18,000 µg/g in the dried product. Phytochemical analysis indicated high contents of total polyphenol (52–56 mg GAE/g), flavonoids (1.5–2.2 mg QE/g), and soluble proanthocyanidins (6.4–9.2 mg ProA2/g), with FD samples consistently outperforming AD. Antioxidant assays confirmed strong activity, particularly in the FD samples.

This study investigates the chemical composition, antioxidant properties, and functional potential of four plant leaves traditionally used as natural wrappers for tamales: banana (Musa paradisiaca), maize (Zea mays), papatla (Canna indica), and choco (Oreopanax capitatus). Despite their widespread culinary use, their physicochemical characteristics and contributions to the sensory and texture properties it confer to tamales remains little explored. The leaves were analysed for fibre content, fatty acid profiles, polyphenols, and volatile compounds, both before and after steam cooking. The results revealed that all leaves are fibre-rich, contributing tensile strength and flexibility, attributes favourable for the wrapping of the tamales. Notably, they exhibited significant antioxidant activity, driven by their Omega-3 fatty acids and polyphenol content. Among the leaves, choco demonstrated the highest levels of volatile compounds and fatty acids after cooking, enhancing its functional properties. Sensory evaluation highlighted choco-wrapped tamales as the most preferred due to their superior flavour and aroma, while banana and papatla leaves improved the firmness and adhesiveness of tamales. These findings underline the potential of these leaves, particularly choco, as sustainable and functional materials offering sensory enhancement in culinary applications.

本研究研究了四种传统上用作玉米卷肉天然包装纸的植物叶片的化学成分、抗氧化性能和功能潜力：香蕉（Musa paradisiaca）、玉米（Zea mays）、木瓜（Canna indica）和巧克力（Oreopanax capitatus）。尽管它们在烹饪中被广泛使用，但它们的物理化学特性以及它们赋予玉米粉蒸肉的感官和质地特性的贡献仍然很少被探索。在蒸煮前后，对叶子的纤维含量、脂肪酸谱、多酚和挥发性化合物进行了分析。结果表明，所有的叶子都富含纤维，有助于拉伸强度和柔韧性，有利于玉米粉蒸肉的包装。值得注意的是，由于它们的Omega-3脂肪酸和多酚含量，它们表现出了显著的抗氧化活性。在所有的叶子中，巧克力在烹饪后挥发性化合物和脂肪酸含量最高，增强了其功能特性。感官评价显示，巧克力包裹的玉米粉蒸肉因其优越的风味和香气而最受青睐，而香蕉和木瓜叶则提高了玉米粉蒸肉的硬度和粘性。这些发现强调了这些叶子的潜力，特别是巧克力，作为可持续的功能性材料，在烹饪应用中提供感官增强。

Tomatoes (Solanum lycopersicum L.) are widely extracted in both fresh and processed forms as a source of antioxidants from the carotenoid group. Lycopene is the most dominant carotenoid compound, accounting for 90 % of the total carotenoids in tomatoes. However, lycopene is thermolabile and begins to degrade rapidly at temperatures above 100 °C. Therefore, selecting an appropriate extraction method is crucial, as factors such as temperature, duration, and solvent type significantly influence the efficiency and recovery of lycopene. In this study, a comparison was made between conventional solvent extraction (Hot & Cold Solvent), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), deep eutectic solvent (DES) extraction, and supercritical carbon dioxide (SCCO₂) extraction. The comparative analysis showed that DES solvents offer a more environmentally friendly and energy-efficient alternative at the laboratory scale, while SCCO₂ is the most viable technique for industrial-scale production due to its high yield, good product purity, and the use of safe and recyclable solvents.

番茄（Solanum lycopersicum L.）作为类胡萝卜素类抗氧化剂的来源，被广泛地以新鲜和加工的形式提取。番茄红素是最主要的类胡萝卜素化合物，占番茄中总类胡萝卜素的90%。然而，番茄红素是耐热性的，在100°C以上的温度下开始迅速降解。因此，选择合适的提取方法至关重要，因为温度、时间、溶剂类型等因素对番茄红素的提取效率和回收率有重要影响。在本研究中，比较了传统溶剂萃取（热&冷溶剂）、微波辅助萃取（MAE）、超声辅助萃取（UAE）、深共晶溶剂（DES）萃取和超临界二氧化碳（SCCO₂）萃取。对比分析表明，在实验室规模上，DES溶剂是一种更环保、更节能的替代方案，而SCCO₂因其产率高、产品纯度好、使用安全、可回收的溶剂而成为最可行的工业规模生产技术。

Berberis lutea and Berberis virgata are wild ethnobotanical species native to the high Andean regions of Peru, specifically the Huancavelica region, where they grow in the province of Acobamba. In high Andean communities, they are used to treat certain ailments due to their medicinal properties and to dye textiles. Currently, there are no studies on their phytochemical composition, making it timely to investigate their benefits and scientific validation. The objective was to characterize the physical properties, polyphenolic components, antioxidant activity, and betalains of the fruits of Berberis lutea and Berberis virgata. The methodology involved collecting ripe berries, measuring their weight and morphology, preparing extracts, and quantifying total polyphenols, antioxidant activity, and total betalains. The results of the morphophysical analysis of the fruits showed a moderately elongated ovoid shape, dark blue color, and little variability in weight and diameter parameters. In terms of bioactive composition, Berberis virgata exhibited significantly higher concentrations of total polyphenols, antioxidant activity, and betalains compared to Berberis lutea. In conclusion, exotic fruits offer significant bioactive compounds, surpassing other fruits in their potential for incorporation into the agro-industrial, pharmaceutical, cosmetic, and agricultural sectors, including propagation, sustainable production, utilization of their functional compounds, and the generation of food additives.

黄小檗（beris lutea）和维加塔小檗（beris virgata）是秘鲁安第斯山脉高海拔地区的野生民族植物物种，特别是万卡维利卡地区，它们生长在Acobamba省。在高安第斯地区，由于它们的药用特性，它们被用来治疗某些疾病，并为纺织品染色。目前还没有对其植物化学成分的研究，因此研究其益处和科学验证是及时的。目的是表征黄小檗和小檗果实的物理性质、多酚成分、抗氧化活性和甜菜碱。方法包括收集成熟的浆果，测量其重量和形态，制备提取物，定量测定总多酚、抗氧化活性和总甜菜碱。果实形态物理分析结果显示，果实呈中等伸长的卵形，颜色为深蓝色，重量和直径参数变化不大。在生物活性成分方面，与黄叶小檗相比，野小檗的总多酚、抗氧化活性和甜菜素含量显著高于黄叶小檗。总之，外来水果提供了重要的生物活性化合物，在农业工业、制药、化妆品和农业领域的潜力超过了其他水果，包括繁殖、可持续生产、其功能化合物的利用和食品添加剂的产生。

This study aims to investigate the nutritional profile, the antioxidant and anti-inflammatory activities of seeds of Telfairia occidentalis and Citrullus lanatus from Cameroun. Proximate, mineral composition and antinutritional factors were determined as well as antioxidant, antiradical and anti-inflammatory activities of plant extracts. The results showed that the seeds contains different levels of macronutrients such as moisture (2.76 - 9.73% fw), proteins (19.25–29.21%), lipids (41.41–61.93%), carbohydrates (5.30–17.80%), crude fibre (1.78–8.43%) and ash (1.11–2.51% dw). They exhibited high amounts of zinc (20.22–86.67 mg/100 g), potassium (407.34–727.80 mg/100 g) and sodium (142.09- 424.09/100 g). Their extracts were rich in total phenols, flavonoids and tannins with the concentration varied from 3.88 to 288.19 mg depending on the type of plant and harvest area. The hydroethanol extract of C. lanatus seeds demonstrated the best antioxidant capacity. For the scavenging assay, the inhibitory concentrations 50% (IC₅₀) ranged from 17.53 to 787.97 μg/ml depending on the nature of radical and the extracts. The anti-inflammatory activities revealed that the extract of T. occidentallis seed showed 69.28% of the inhibition on red blood cell hemolysis while that of C. lanatus demonstrated 98.93% of the inhibition effect on egg albumin denaturation. Seeds may serve as protein and mineral sources for infant formula.
