| Abstract: | Stem bark ofTetrapanax papyriferumC. Koch., Araliaceae, yielded new triterpene glycosides 28-O- -L-rhamnopyranosyl-(1 4)-O-(6-O-acetyl- -D-glucopyranosyl)-(16)-O--D-glucopyranosyl esters of the 3-O--D-glucopyranosyl-(13)--D-galactopyranosyl-(12)]-O--L-arabinopyranosides of oleanolic and echinocystic acids. The structures of these substances were established using chemical and physicochemical methods |
