Three new flavonol glycosides were isolated from the leaves of Helicia nilagirica Beed.. The structures were elucidated as kaempferol-3-O-b-D-xylopyranosyl-(16)-b-D-glyco- pyranosyl-(12)-a-L-rhamnopyranoside, quercetin-3-O-b-D-xylopyranosyl-(16)-b-D-glycopy- ranosyl-(12)-[-b-D-xylopyranosyl-(14)]-a-L-rhamnopyranoside, and quercetin-3-O-b-D- xylopyranosyl-(16)-b-D-glycopyranosyl-(12)-a-L-rhamnopyranoside, named as Helicianeoside A、B and C, respectively.
Three new flavonol glycosides were isolated from the leaves of Helicia nilagirica Beed .. The structures were elucidated as kaempferol-3-ObD-xylopyranosyl- (16) -bD- glyco- pyranosyl- (12) -aL- rhamnopyranoside, ObD-xylopyranosyl- (16) -bD-glycopyranosyl- (12) - [- bD-xylopyranosyl- (14)] - aL-rhamnopyranoside, and quercetin-3- ObD- xylopyranosyl- (12) -aL-rhamnopyranoside, named as Helicianeoside A, B and C, respectively.
