Eicosenoic acid and other fatty acids ofSapindaceae seed oils.
The seed oils of 11 species ofSapindaceae were examined, and their fatty acid composition was determined.cis-11-Eicosenoic acid was identified as the major fatty acid ofKoelreuteria 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 ofKoelreuteria andCardiospermum are good potential sources of 11-eicosenoic acid.
