Abstract

Abstract:

A triterpene saponins compound (compound 1) was isolated from the roots of Dipsacus asperoides C.Y.Cheng et T.M.Ai. and its structure was established as 3-O-[β-D-xylopyranosyl(1-4)-β-D-glucopyranosyl(1-4)][α-L-rhamnopyranosyl (1-3)]β-D-glucopyranosyl(1-3)-α-L-rhamnopyranosyl(1-2)-α-arabinopyranosyl-hederagenin-28-O-β-D-glucopyranoside-(1-6)-β-D-glucopyranoside ester. This paper describes the application of HSQC-TOCSY and other techniques in the NMR assignment and structure elucidation of this compound.

Key words: NMR, HSQC-TOCSY, triterpenoid saponin, dipsacus asper
