A pair of cadinane-type sesquiterpene enantiomers and other chemical constituents from the whole plants of Chloranthus henryi

Abstract

Continual phytochemical investigation on the whole plants of Chloranthus henryi Hemsl afforded fourteen compounds (1–14), including eight sesquiterpene monomers (1–8), four sesquiterpene dimers (9–12), a diterpene (13), and a simple coumarin (14). The structures of these compounds were assigned by means of spectroscopic techniques and ECD calculations. Compounds 1a and 1b are a pair of cadinane-type sesquiterpene enantiomers, while compounds 3–7 and 11–14 are isolated from C. henryi for the first time. Moreover, the chemotaxonomic significance corresponding to the aforementioned compounds was investigated.
