Abstract

Abstract: Three new triterpenoid glycosides were isolated from the stems of Decaisnea forgesii used as an antitheumatic and antitussive drug for a long time in Chinese folk medicine. Their structures were determined on basis of chemical method, FABMS, homonuclear and het-eronuclear correlation experiments including ¹H-¹H COSY, ¹H-¹³C COSY, TOCSY and NOESY techniques. All of the ¹H and ¹³C NMR chemical shifts of the three new triterpenoid glycosides were assigned for the first time.

Key words: Decaisnea fargesii, Triterpenoid glycoside, 2D NMR
