摘要:
A novel acylated quercetin glycoside, floralpanasenoside A (1) and five known flavonoid glycosides, panasenoside (2), quercetin 3-O-(2''-beta-D-glucopyranosyl)-beta-D-galactopyranoside (3), trifolin (4) kaempferol 7-O-alpha-L-rhamnoside (5), and afzelin (6) were isolated from the flower buds ofPanax ginseng. Their structures were established by spectroscopic data and comparison with the literature values. Four of the six isolated compounds including1(IC50= 62.4) exhibited alpha-glucosidase inhibitory activity with IC50 values lower than acarbose (385.2 mu M). The molecular docking study indicated that1bound to the active site of alpha-glucosidase with numerous hydrogen bond interactions. [GRAPHICS] .
