Unsaturated C₁₈ α‐hydroxy acids in<i>Salvia nilotica</i>

Abstract

Abstract The oil of Salvia nilotica Jacq. (Labiatae) seed contains 0.6% α‐hydroxyoleic, 4.2% α‐hydroxylinoleic, and 5.4% α‐hydroxylinolenic acids. The first two have not been found previously in seed oils. In addition to the common fatty acids, also identified were small amounts of three unsaturated C 17 acids and one branched chain C 17 acid. Methyl esters of the component fatty acids were fractionated by both column and thin‐layer chromatography. These esters were identified by combination of gas chromatography, GC‐mass spectrometry, ozonolysis‐GC, infrared, and nuclear magnetic resonance.
