title: Flavonol glycosides from the leaves of Indigofera zollingeriana.
abstract: Two new flavonol glycosides were isolated from the 1-butanol (1-BuOH)-soluble fraction of a methanol (MeOH) extract of the leaves of Indigofera zollingeriana, along with four flavonol glycosides and three known megastigmane glucosides. The structures of the new compounds were elucidated by spectroscopic analyses as kaempferol 3-O-β-D-(2"-O-β-D-apiofuranosyl)glucopyranoside 7-O-α-L-rhamnopyranoside and 3-O-β-D-(2"-O-β-D-apiofuranosyl, 6"-O-α-L-rhamnopyranosyl)glucopyranoside 7-O-α-L-rhamnopyranoside.
