were isolated from stem bark ofTetrapanax papyriferumC. Koch (Araliaceae). The structures of oleanolic and echinocystic acid 3-O--L-arabinopyranosides, oleanolic and echinocystic acid 3-O--D-glucopyranosyl-(13)-O--L-arabinopyranosides, and oleanolic and echinocystic acid 3-O--D-galactopyranosyl-(12)-O--L-arabinopyranosides, respectively, were proposed.

Stem bark ofTetrapanax papyriferumC. Koch., Araliaceae, yielded new triterpene glycosides 28-O--L-rhamnopyranosyl-(14)-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 相似文献
