Abstract

Root chemicals and evolutionarily neutral DNA regions in L. cyathiceps samples collected in the Zhongdian (Shangrila) County of Yunnan, P. R. China, were examined. Twenty compounds were isolated, including three new ones, 1__β__,10__β__‐epoxy‐6__β__‐(propionyloxy)furanoeremophilan‐9‐one (6), 1__β__,10__β__‐epoxy‐8__α__‐ethoxyeremophila‐6,11‐diene (14), and 11__α__H‐6__β__‐isobutyryloxy‐1__β__,10__β__,7__β__,8__β__‐diepoxyeremophilan‐12,8__α__‐olide (15). The chemical diversity was found to be limited, with cacalol (1) and 6‐(acyloxy)furanoeremophilan‐9‐ones (4 and/or 5) being major components in all the samples. The nuclear ribosomal RNA gene was also found to harbor little variation, although two distinct sequence types were found for the plastid atpB‐rbcL intergenic region.
