Abstract

Two new bicyclic sesquiterpenes, namely 6α,9α-dihydroxycadinan-4-en-3-one (1) and guai-3-en-10α-ol (2), together with one known sesquiterpene were isolated from the stems of Kadsura heteroclita, which is a Tujia ethnomedicine called 'Xue Tong'. Their structures were elucidated by using spectroscopic analyses and by comparing the NMR data with those reported previously.

Keywords: Kadsura heteroclita; Schisandraceae; Tujia ethnomedicine; Xue Tong; sesquiterpene.
