Abstract

Wild edible plants (WEPs) from the Western Himalayas consisting of three green leafy vegetables (GLVs), viz., Amaranthus spinosus, Urtica dioica, and Zanthoxylum armatum, and three fruits, namely, Ficus auriculata, Cordia obliqua, and Momordica dioica were characterized for their nutritional and phytochemical composition. We identified 107 compounds consisting of polyphenols, terpenoids, amino acids, and fatty acid derivatives through UHPLC-QTOF-IMS-based metabolomics. GLVs (A. spinosus and U. dioica) scored best in terms of proteins, micronutrients, carotenoids, and total polyphenols when compared to fruits. Polyunsaturated fatty acids, particularly alpha-linolenic acid, are abundant among WEPs. U. dioica possessed the highest radical scavenging activity, while A. spinosus and M. dioica exhibited strong reducing power activity. Strong α-glucosidase inhibition activity was observed with A. spinosus, Z. armatum, and M. dioica. Polyphenols, particularly flavonoids, from fruits were relatively more bioaccessible compared to GLVs. Potential applications of GLVs for combating protein and iron deficiency as well as wild fruits for functional food development should be explored further.

喜马拉雅山脉西部野生食用植物中的生物活性化合物：营养概况、基于 UHPLC-QTOF-IMS 的植物化学特征及其体外胃肠消化率

研究人员对喜马拉雅山脉西部的野生食用植物（WEPs）进行了营养和植物化学成分鉴定，其中包括三种绿叶蔬菜（GLVs），即苋菜（Amaranthus spinosus）、荨麻（Urtica dioica）和芒果（Zanthoxylum armatum），以及三种水果（Ficus auriculata、Cordia obliqua 和 Momordica dioica）。我们通过基于 UHPLC-QTOF-IMS 的代谢组学鉴定了 107 种化合物，包括多酚、萜类化合物、氨基酸和脂肪酸衍生物。与水果相比，GLV（A. spinosus 和 U. dioica）在蛋白质、微量营养素、类胡萝卜素和总多酚方面得分最高。多不饱和脂肪酸，尤其是α-亚麻酸，在西柚中含量丰富。U. dioica 具有最高的自由基清除活性，而 A. spinosidase 和 M. dioica 则表现出很强的还原力活性。A. spinosus、Z. armatum 和 M. dioica 具有很强的 α-葡萄糖苷酶抑制活性。与 GLVs 相比，果实中的多酚类物质，尤其是黄酮类物质更容易被生物利用。应进一步探索 GLVs 在防治蛋白质和铁缺乏症方面的潜在应用，以及野生水果在功能食品开发方面的潜在应用。
