Abstract: The chemical constituents of Rabdosia rubescens(Hemsl.) Hara herb were studied. Seven compounds were isolated and their structures were elucidated by various spectroscopic methods as bisrubescensin D(Ⅰ), (10Z,14Z)-9,16-dioxo-octadec-10,12,14-trienoic acid (Ⅱ), 2'-acctamido-3'-phenyl propyl 2-benzamido-3-phenyl propionate (Ⅲ), α-amyrin (Ⅳ), β-amyrin (Ⅴ), olean-12-en-2β,3β-diol-28-oic acid (augustic acid, Ⅵ), 2α-hydroursolic acid (Ⅶ). Compound Ⅰ is a novel asymmetric ent-kauranoid dimmer, compound Ⅱ is a new unsaturated fatty acid, compounds Ⅲ and Ⅵ were obtained from this genus of plants for the first time, and compound Ⅴ was obtained from this plant for the first time.
Key words: Rabdosia rubescens(Hemsl.) Hara herb, ent-kauranoid dimmer, fatty acid, alkaloid, triterpene
