Flavonoid glycosides from the fruits of and their anti-oxidant and -glucosidase inhibitory activities.

Three new flavonoid glycosides, embeliaflavosides A-C (), together with eight known flavonoid glycosides (), were isolated from the fruits of . Their structures were established based on the analyses of spectroscopic data. Compounds were evaluated for antioxidant and -glucosidase inhibitory activities. The results revealed that compounds owned significant ABTS radical scavenging activity with IC values of 2.52-9.78 µM, and DPPH scavenging activity with IC values of 7.56-26.47 µM, respectively. However, -glucosidase inhibition assay indicated that all the isolates were inactive.[Formula: see text].
