cis‐Vaccenic acid in pulp lipids of commonly available fruits

This is the authors' abstract. We don't add key points for this paper.

Fatty acids of commonly available fruit pulps have been analyzed by capillary gas chromatography of their methyl esters and by gas chromatography‐mass spectrometry as their dimethyl disulfide adducts. The gas chromatographic and mass spectrometric data proved that these fruits always contained cis ‐vaccenic ( cis ‐11‐octadecenoic) acid as a component fatty acid of their pulp lipids. The concentration of cis ‐vaccenic acid in total octadecenoic acids ranged from 1.9% to 95.1% in the fruit pulps examined. The highest concentration of this acid was detected in pulp lipids of Japanese persimmon ( Diospyros kaki ). In fruit pulp lipids, cis ‐vaccenic acid was a common octadecenoic acid as well as oleic acid.
