摘要
以3个沙棘品种(亚历山大12号、实优1号和丘伊斯克×中国无刺雄)的果实为材料,通过气-质联用法建立了沙棘种子油中脂肪酸组成的微量分析技术。脂肪酸用标准品结合质谱进行定性确证分析,脂肪酸组成用峰面积归一法计算。结果表明,沙棘种子油中富含不饱和脂肪酸(71.2%～76.0%),其中亚油酸(C18∶2n-6)含量最高(35.6%～39.0%),α-亚麻酸(C18∶3n-3)含量次之(27.8%～33.4%)。
A microanalysis method which was based on gas chromatography-mass spectrometry （GC-MS） was established to i- dentify compositions of fatty acids in 3 kinds of seed oil of sea buckthom, including Yalishanda-12, Shiyou-1 and Qiuy- isikexChinese-Wucixiong. Fatty acids were qualitatively determined according to the standards of fatty oil by MS. The compo- sitions of fatty acids in seed oil were calculated by peak area normalization. The results indicated that unsaturated acids （71.2%-76.0%） were rich in seed oil. The content of linoleic acid was highest with the range between 35.6% and 39.0%, α-linolenic acid was second with the range between 27.8% and 33.4%.
