Echinodol: A New Cembrene Derivative from<i>Echinodorus grandiflorus</i>

Abstract

The aerial parts of ECHINODORUS GRANDIFLORUS Mitch., a species of Alismataceae from Brazil, yielded a new diterpene alcohol named echiriodol ( 1) in addition to the known steroid stigmasterol. Its constitution and relative configuration were established by high resolution NMR techniques.
