Abstract:Our preliminary screening study revealed that the methanolic extract of Stholobus parviflorus (Roxb.) exhibited potent a-glucosidase inhibitory activity with an IC50 value of 0.05 μg mL-1. Therefore, we carried out activity-guided fractionation of the MeOH extract and isolated three compounds. These compounds were determinated as ferulic acid (1), protocatechuic acid (2) and epicatechin (3) by analysis of spectroscopic data. The IC50 values of these compounds were 45.30, 23.04 and > 100 μM, respectively. Ac… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
