Alchornea cordifolia seed oil: A rich source of a new C20 epoxide, (+)cis-14,15-epoxy-cis-11-eicosenoic acid

Abstract

A C20 homolog of vernolic acid has been found at the 50% level in Alchornea cordifolia, Euphorbiaceae, seed oil. This new acid, (+)cis-14,15-epoxy-cis-11-eicosenoic (alchornoic) acid, was isolated by high-pressure liquid chromotography and characterized by mass spectrometry, nuclear magnetic resonance and infrared spectroscopy, optical rotary dispersion, and ozonolysis-gas-chromotography. © 1976 American Oil Chemists' Society.
