摘要
采用索氏提取法提取辽南地区的野生软枣猕猴桃全果及其籽中脂肪酸。甲酯化处理后,采用气相色谱-质谱联用(GC-MS)方法分离和鉴定。结果表明:在野生软枣猕猴桃全果中分离鉴定出7种脂肪酸,分别是棕榈酸(6.66%)、亚油酸(10.57%)、亚麻酸(77.78%)、硬脂酸(3.09%)、10,13-十八碳二烯酸(0.2%)、11-二十碳烯酸(0.8%)、花生酸(0.14%);在野生软枣猕猴桃籽中分离鉴定出4种脂肪酸,分别是棕榈酸(3.24%)、亚油酸(5.40%)、亚麻酸(42.49%)、硬脂酸(2.39%)。其中亚麻酸的含量最高,分别占77.78%和42.49%
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.
