摘　　要：分析比较了四川地区主栽品种金艳、红阳、红实2号、金实1号、海沃德、徐香及新西兰主栽品种猕猴桃籽出油率,并采用GC-MS结合PCA分析了7个品种脂肪酸组成及角鲨烯相对含量。结果显示:海沃德猕猴桃籽出油率最高(28.28%),亚麻酸、油酸、亚油酸等不饱和脂肪酸为猕猴桃籽油中主要的脂肪酸(85.7%~87.1%)。不同品种之间差异较大的脂肪酸有亚麻酸、十六烷酸和十八烷酸,但不同猕猴桃籽油脂肪酸构成差异较小。不同品种籽油中角鲨烯相对含量在1.01%~1.72%,金艳含量最高(1.72%),金实1号含量最低(1.01%)。The yields of kiwi seed oils of Jinyan,Hongyang,Hongshi No.2,Jinshi No.1,Hayward,Xuxiang mainly cultivated in Sichuan areas,China and Sungold mainly cultivated in New Zealand are analyzed and compared,the fatty acid composition and squalene relative content of 7 varieties are analyzed by GC-MS combined with PCA.The results show that the yield of Hayward kiwi seed oil is the highest(28.28%),and the unsaturated fatty acids such as linolenic acid,oleic acid and linoleic acid are the main fatty acids in kiwi seed oils(85.7%~87.1%).The fatty acids of linolenic acid,hexadecanoic acid and octadecanoic acid have great differences among different cultivars,but the fatty acid composition of different kiwi seed oils has little difference.The relative content of squalene in different varieties of seed oils ranges from 1.01%to 1.72%,Jinyan has the highest content(1.72%)and Jinshi No.1 has the lowest content(1.01%).
