Fatty Acid Composition in Fruit of Wild Actinidia arguta Sieb.et Zucc

The fatty acid composition of the whole fruit and seeds of Actinidia arguta Sieb.et Zucc wildly grown in South Liaoning was analyzed by Soxhelt extraction and subsequent methyl esterification coupled to gas chromatography-mass spectrometry(GC-MS).Seven fatty acids were identified in the whole fruit of Actinidia arguta Sieb.et Zucc,including hexadecanoic acid(6.66%),9,12-octadecadienoic acid(Z,Z)-(10.57%),9,12,15-octadecatrienoic acid(77.78%),octadecanoic acid(3.09%),10,13-octadecadienoic acid(0.2%),11-eicosenoic acid(0.8%),and eicosanoic acid(0.14%).The seeds of the plant,however,contained 4 identified fatty acids,namely,hexadecanoic acid(3.24%),9,12-octadecadienoic acid(Z,Z)-(5.40%),9,12,15-octadecatrienoic acid(42.49%)and octadecanoic acid(2.39%).The compounds with the highest contents in the whole fruit and seeds of the plant were both 9,12,15-octadecatrienoic acid,which were 77.78%and 42.49%respectively.
