摘要：

The new flavonol glycosides kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1->3)-alpha-L-rhamnopyranosyl-(1->6)-beta-D-glucopyranoside] and kaempferol-3-O-[alpha-L-rhamnopyranosyl-( 1->3)-(4'''-O-acetyl)-alpha-L-rhamnopyranosyl-(1->6)-beta-D-glucopyranoside] have been isolated from China green tea. Kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1->3)-alpha-L- rhamnopyranosyl-(1->3)-alpha-L-rhamnopyranosyl-(1->6)-beta-D-galactopyranoside] was identified for the first time in tea.
