title: Triterpenoid glycosides from Schefflera lucantha.
abstract: Three new triterpenoid glycosides were isolated from the leaves of Schefflera lucantha Viguier. Based on the spectroscopic data, especially 2D NMR, the structures of glycosides have been established as 3-O-[alpha-L-rhamnopyranosyl (1-->2)-beta-D-glucopyranosyl (1-->2)-beta-D-glucuronopyranosyl] betulinic acid, 3-O-[alpha-L-rhamnopyranosyl (1-->2)-beta-D-xylopyranosyl (1-->2)-beta-D-glucuronopyranosyl]betulinic acid and 3-O-[alpha-L-rhamnopyranosyl(1-->2)-beta-D-glucopyranosyl (1-->2)-beta-D-glucuronopyranosyl]oleanolic acid.
