revealed in many studies that the biological activities of flavonoids could be improved after glucosylation. Three prenylated quercetins were prepared in this study, and microbialtransformation was carried out in order to identify derivatives of prenylquercetins with increased water solubility and improved bioavailability. The fungus M. hiemalis was proved to be capable of converting prenylquercetins into
槲皮素是分布最广泛的类黄酮之一,已被发现具有多种生物活性,包括抗氧化、抗癌和抗炎作用。据报道,类黄酮的生物活性增强通常与核异戊二烯化密切相关,如 8-异戊二烯槲皮素和 5'-异戊二烯槲皮素所示。许多研究还表明,糖基化后可以提高黄酮类化合物的生物活性。本研究制备了三种异戊二烯化槲皮素,并进行了微生物转化,以鉴定具有增加水溶性和改善生物利用度的异戊二烯槲皮素衍生物。真菌 M. hiemalis 被证明能够将异戊二烯槲皮素转化为更具极性的代谢物,并被选择用于制备发酵。获得了六种新的糖基化代谢物,并通过核磁共振和质谱分析阐明了它们的化学结构。所有微生物代谢物都显示出水溶性的改善。
