Abstract

A new quaiane-tgpe sesquiterpene was isolated from the 95% ethanol extract of the rhizomes of Acorus calamus by silica gel and sephadex LH-20 column chromatographic methods. Structure and absolute configuration of the sesquiterpene were elucidated by spectroscopic data and X-ray crystallographic analysis, and named as 1R,5R,7S-guaiane-4R,10R-diol-6-one.

Keywords: 1R,5R,7S-guaiane-4R,10R-diol-6-one; Acorus calamus; guaiane-type; sesquiterpene.
