Phytochemical investigation of the underground part of the blossoming tropical orchid Arundina graminifolia led to the isolation of six new glucosyloxybenzyl 2R-benzylmalate derivatives named arundinosides L-Q (1-6) together with 5 known compounds arundinosides D-F, J and K (7-11). The structures of the isolated compounds were determined by extensive spectroscopic data analysis. The anti-α-glucosidase and antioxidant activities of the isolated compounds were determined. The result indicated that compounds 4-6 and 9 showed moderate to weak α-glucosidase inhibitory effects as well as moderate antioxidant effect.Read less <
