Isolation and Structures of Hedyotisol-A, -B, and -C Novel Dilignans from Hedyotis Lawsoniae

Abstract

Three new dilignans, hedyotisol-A (1a), -B (2a), and -C (3a), were isolated from the leaves of Hedyotis lawsoniae and their structures were examined. These compounds are constructed from a syringaresinol unit and two phenylpropane units, and they are stereoisomeric with each other. © 1984, The Pharmaceutical Society of Japan. All rights reserved.
