Diterpenes and diterpene xylosides from Conyza trihecatactis

Abstract

From the leaves of Conyza trihecatactis we have isolated the labdane-type diterpenes and diterpene xylosides ent-sclareol, ent-3β-hydroxymanool, ent-manool 13-O-β-d-xylopyranoside and ent-sclareol 13-O-β-d-xylopyranoside. Structure elucidation was achieved by spectroscopic methods. © 1994.
