Article abstract of DOI:10.1016/0031-9422(91)83647-4

In addition to 3-epi-betulinic acid, three triterpene glycosides were isolated from leaves of Schefflera octophylla.The structures of the glycosides have been determined as 28-O-<α-L-rhamnopyranosyl(1->4)-O-β-D-glucopyranosyl(1->6)->-β-D-glucopyranosides of 3α-hydroxy-lup-20(29)-ene-23,28-dioic acid, 3α,11α-dihydroxy-lup-20(29)-ene-23,28-dioic acid and 3-epi-betulinic acid by spectroscopic data and chemical transformations.The last two compounds were found for the first time in the plant kingdom.
