Fatty acid compositions of the oils of celtis sinensis var. japonica and zelkova serrata

Abstract

Oils were extracted from the pits of Celtis sinensis Pers. var. japonica Nakai and the fruits of Zelkova serrata Makino, of the family Ulmaceae. The oils were examined for their characteristics and fatty acid composition. The percentages of component acids of Celtis and Zelkova oils determined by gas liquid chromatography of their methyl esters were, respectively: propionic (-, 0.9), butyric (-, trace), caproic (-, 0.1), caprylic (-, 7.3), capric (-, 76.5), lauric (-, 3.3), myristic (0.1, 1.0), palmitic (6.8, 2.8), hexadecenoic (trace, -), stearic (3.5, 0.4), oleic (7.5, 3.9), linoleic (80.0, 3.3), linolenic (2.1, 0.5), and arachidic (trace, -) acids. © 1978 American Oil Chemists' Society.
