| Description | Ombuoside (Ombuin-3beta-rutinoside) has antifungal activity. Ombuoside shows significant antioxidant activity in the DPPH, and TEAC, reducing power assays.Ombuoside is a glycoside ombuoside isolated from Gynostemma pentaphyllum. |
| In vitro | Ombuoside及其合成衍生物octa-acetylOmbuoside、ombuine和retusine针对多株革兰氏阳性和阴性细菌以及酵母Candida albicans的抗菌活性进行了研究，采用琼脂扩散法。黄烷醇苷Ombuoside及相应的无糖体ombuine，均对Corynebacterium diphtheria、Staphylococcus aureus、Escherichia coli和Candida albicans展现了中等程度的活性。octa-acetylOmbuoside和retusine对革兰氏阳性细菌C. diphtheria和S. aureus亦表现出一定活性，但对革兰氏阴性细菌和Candida albicans无效[1]。 |
