Abstract:
Objective To isolate and identify the chemical constituents in the polar part of the Ancecotochilus roxburghii.Methods The flavonoids were isolated by column chromatography and their structures were elucidated through spectral analyses such as FAB-MS and NMR.Results Five flavonoids were isolated and identified as quercetin 7-O-?-D-glucoside(Ⅰ),quercetin 3-O-?-D-rutinoside(Ⅱ),isorhamnetin-3,4′-O-?-D-diglucoside(Ⅲ),isorhamnetin-3,7-O-?-D-diglucoside(Ⅳ),and isorhamnetin-7-O-?-D-diglucoside(Ⅴ).Conclusion All the compounds are obtained from A.roxburghii for the first time.
