Eicosenoic acid and other fatty acids of Sapindaceae seed oils

Abstract

The seed oils of 11 species of Sapindaceae were examined, and their fatty acid composition was determined. cis-11-Eicosenoic acid was identified as the major fatty acid of Koelreuteria paniculata. It was present in nine of the 11 species in amounts from 8-60% of the total fatty acids and is evidently a common component of oils of this plant family. Arachidic acid was present in amounts up to 11%. Only three of the oils had acids of chain length greater than C-20. Seed oils of certain species of Koelreuteria and Cardiospermum are good potential sources of 11-eicosenoic acid. © 1967 American Oil Chemists' Society.
