Diarylheptanoids from Alpinia officinarum

Abstract

A new diarylheptanoid, along with five known diarylheptanoids, was isolated from the rhizomes of Alpinia officinarum (Zingiberaceae). The structure of the new compound was determined to be trans,trans-1(3′-methoxy-4′-hydroxyphenyl)-7-phenyl-5-ol-4,6-dien-3-heptanone on the basis of spectral and chemical evidence.
