Triterpenoid glycosides from Schefflera lucantha.
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.
