title: Flavonoids and saponins from Zizyphus incurva.
abstract: A new flavonol triglycoside, myricetin-3-O-[β-xylopyranosyl-(1-2)-α-rhamnopyranoside]-4'-O-α -rhamnopyranoside, named as bayarin (1), was isolated from the aerial parts of Zizyphus incurva Roxb. (Rhamnaceae) along with eight known compounds: six flavonoids and two saponins. All of these compounds were isolated for the first time from this plant. Structures of these compounds were elucidated on the basis of spectroscopic data.
