Abstract:	Minor monodesmoside triterpene glycosides St-A, St-B, St-C ₁ , St-D ₁ , St-C ₂ , and St-D ₂ 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. Glycosides St-C ₂ , St-D ₁ , and St-D ₂ are new triterpene glycosides. The structures of the isolated compounds were established using chemical methods and NMR spectroscopy.

Keywords:	Tetrapanax papyriferum Araliaceae triterpene glycosides oleanolic and echinocystic acid glycosides
