Abstract
Methyl esters from seed oils of four Chenopodiaceae species are unusual in that they contain methylcis‐5‐hexadecenoate (4.6–12%) and methyl 5‐octadecenoate (1.1–1.2%). There are indications of small amounts of 18∶25,9 and 18∶35, 9, 12 along with unsaturated acids commonly found in seed oils‐oleic (14–21%), linoleic (53–57%) and linolenic (3.5–7.8%). Fatty acid composition of the oils was determined by gas chromatography, and positions of the double bonds were established by application of gas chromatography‐mass spectrometry to the methoxylated methyl esters.Keywords
