摘　　要：选取陕西神木、陕西榆阳、内蒙固阳、内蒙乌审旗、河北丰宁5个不同种源地的长柄扁桃种籽为试材,采用索式提取法对不同种源地长柄扁桃种仁的含油量进行了分析,并用气相色谱技术分析了其脂肪酸成分。结果表明:种仁的含油量除河北丰宁的低于50.00%以外,其余的均高于50.00%,含量范围在49.85%～54.89%;脂肪酸主要是油酸、亚油酸、少量的软脂酸、硬脂酸、棕榈油酸,个别品种还有微量的亚麻酸、顺-11-二十碳烯酸、花生酸;不饱和脂肪酸含量达90.00%以上,饱和脂肪酸含量较低,可以开发成健康的食用油产品,具有较高的开发前景。Selecting five different seeds of Amygdalus pedunculata Pall. from Shaanxi Shenmu, Shaanxi Yuyang, Inner Mongolia Guyanag, Inner Mongolia Wushenqi, Hebei Fengning as materials,oil content of Amygdalus pedunculata Pall. from different provinces were analyzed using soxhlet extractor and also fatty acid composition of the oil were analyzed by gas chromatography. The results showed that the oil content of most species extracted from seed kernels were higher than 50. 00~,with the oil content percentage ranged from 49. 85~ to 54. 89~, except from Hebei Fengning less than 50. 00 ~. The fatty acid were mainly composed of oleic acid, linoleic acid, palmitic acid, stearic acid,and palmitoleic acid. In some individual species, there were a small amount of linolenic acid, cis-ll-eicosenoic acid, and eicosanoic acid. More than 90. 00 % content of the fatty acid were unsaturated fatty acids,with low saturated fatty acid contents. Oil extracted from these species can be develop into healthy edible oil products,with higher development prospects.
