title: Flavonoid glycosides from the leaves of Cissus ibuensis hook (vitaceae).
abstract: The bioactive N-butanol fraction of the ethanol extract of the leaves of Cissus ibuensis was fractionated over silica Gel column to give Quercetin 3-O-rutinoside (I) and mixtures of Flavonoids (A2). A2 was fractionated using reverse phase HPLC to give Kaempferol 3-O-α-rhamnopyranosyl (1→6)-β-D-galactopyranoside (II), Kaempferol 3-O-rutinoside(III) and Kaempferol3-O-α-rhamnopyranosyl (1→6)-α-rhamnopyranosyl(1→2)-β-D-galactopyranoside (IV). The structures were elucidated by NMR spectroscopy and compared with literature.
