Membrane vesicles isolated from vegetable tissues have shown promise in encapsulation technologies used in industries like food and cosmetics, offering innovative approaches to product development. However, their associated linked metabolites have not been studied. Lemon vesicle research not only adds value to the lemon crop ( L.), one of the most widely cultivated fruit trees in the world, is a source of bioactive compounds such as phenolics and organic acids. In this study, the influence of elicitation with ZnSO and methyl jasmonate, which modulate the bioactive metabolites, on fruit membrane vesicle bond metabolites was studied. The study showed that foliar application of ZnSO increased phenolic compounds as caffeic, sinapic, and chlorogenic acids and the flavonoid hesperidin by about 20% in lemons. Furthermore, a clear interaction between vesicles and citrate and ascorbate that were increased by methyl jasmonate were associated with their higher bioactivity. This was related to the double intrinsic in vitro antioxidant activities of these vesicles.
从植物组织中分离出的膜泡在食品和化妆品等行业的封装技术中显示出了应用前景，为产品开发提供了创新方法。然而，与其相关联的代谢物尚未得到研究。柠檬膜泡研究不仅为柠檬作物（L.）增添了价值，柠檬是世界上种植最广泛的果树之一，是酚类和有机酸等生物活性化合物的来源。在本研究中，研究了用硫酸锌和茉莉酸甲酯诱导对果实膜泡结合代谢物的影响，硫酸锌和茉莉酸甲酯可调节生物活性代谢物。研究表明，在柠檬上叶面喷施硫酸锌可使咖啡酸、芥子酸和绿原酸等酚类化合物以及类黄酮橙皮苷增加约20%。此外，茉莉酸甲酯增加的囊泡与柠檬酸盐和抗坏血酸盐之间存在明显的相互作用，这与它们较高的生物活性有关。这与这些囊泡的双重内在体外抗氧化活性有关。
