NEW MONOTERPENOIDS FROM CYNANCHUM HANCOCKIANUM

Abstract

Five monoterpenoids have been isolated from the roots of Cymanchum hancockianum(Maxim)AI. Iljinski. Their structures were determined on the basis of spectral evidence. The threenew compounds are: 4-p-menthane-1,7,8-triol(Ⅲ), neohancoside A (Ⅳ), neohancoside B(Ⅴ), andthe two knowns. 4-p-menthene-1-8, 9-diol(Ⅰ), and 4-p-menthane-1 ,8,9-triol(Ⅱ). Compound Vwas purified by acetylation.
