摘要

A new eudesmane sesquiterpene glycoside, named funingensin A (1), together with a novel cyclic ether based on the cadalane skeleton, named funingensin B (2), were isolated from the roots of Parepigynum funingense. Their structures were elucidated by spectroscopic methods, including one- and two-dimensional NMR (COSY, HMQC, HMBC and ROESY).
