Abstract
The new flavonol glycosides kaempferol-3-O-[α-L-rhamnopyranosyl-(1→3)-a-L-rhamnopyranosyl-(1-6)-β-D-glucopyranoside] and kaempferol-3-O-[α-L-rhamnopyranosyl-(1→3)-(4′″-O-acetyl)-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside] have been isolated from China green tea. Kaempferol-3-O-[α-L-rhamnopyranosyl-(l→3)-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside] was identified for the first time in tea.
