Terminalia chebula seed oil—a minor source of 12‐hydroxyoctadec‐cis‐9‐enoic acid: Natural products as a source for the food and agricultural industries

Abstract Terminalia chebula , Retz seed oil belonging to the Combretaceae plant family, was found to contain 12‐hydroxyoctadec‐ cis ‐9‐enoic acid (20.5% of the total silylated methyl esters) previously hitherto unknown in the Terminalia genera. The identification and characterisation was based on thin‐layer chromatography, ga:‐liquid chromatography, and ultraviolet, infrared, nuclear magnetic resonance and mass spectral analysis, and chemical degradations.
