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 leads to 2)-beta-D-glucopyranosyl (1 leads to 2)-beta-D-glucuronopyranosyl] betulinic acid, 3-O-[alpha-L-rhamnopyranosyl (1 leads to 2)-beta-D-xylopyranosyl(1 leads to 2)-beta-D-glucuronopyranosyl] betulinic acid and 3-O-[alpha-L-rhamnopyranosyl(1 leads to 2)-beta-D-glucopyranosyl (1 leads to 2)-beta-D-glucuronopyranosyl]oleanolic acid.
