Abstract:

A triterpene saponin was extracted from traditional Chinese medicine Cucurbita pepo cv Dayangua. Its structure was determined by 2D NMR. Complete assignment of the 1H and 13C chemical shifts for the compound was obtained. The structure was elucidated to be cucurbitacin E 2-O-b-D-glucoside.

Key words: NMR, complete assignment, 2D NMR, cucurbitacin E 2-O-b-D-glucoside, cucurbita
