Abstract

The fatty acid compositions of the seed oils of Haematostaphis barteri (blood plum) and Ximenia americana (Wild olive) plants were determined by the Gas Chromatography Mass Spectroscopy (GC-MS) technique. H. barteri contained six fatty acids with oleic (69.35%) and stearic (15.40%) the most abundant unsaturated and saturated fatty acids, respectively. Unsaturated higher fatty acids, namely Eicosadienoic (6.92%) and Erucic acid (2.74%) were detected and the total unsaturation for the oil was 79.01%. For X. americana, 10 fatty acids were identified of which seven were unsaturated yielding a total unsaturation of 92.42%. The oil contained essential fatty acids that is, Linoleic (1.34%), Linolenic (10.31%), Arachidonic (0.60%) and varying levels of unsaturated higher fatty acids, namely, Eicosatrienoic (3.39%), Erucic (3.46%) and Nervonic (1.23%) acids. The level of Oleic acid (72.09%) in the oil was close to the value for H. barteri.

摘要

采用气相色谱 - 质谱联用（GC-MS）技术测定了血桐（血李）和美洲西门木（野橄榄）植物种子油的脂肪酸组成。血桐含有六种脂肪酸，其中油酸（69.35%）和硬脂酸（15.40%）分别是最丰富的不饱和脂肪酸和饱和脂肪酸。检测到不饱和高级脂肪酸，即二十碳二烯酸（6.92%）和芥酸（2.74%），该油的总不饱和度为79.01%。对于美洲西门木，鉴定出10种脂肪酸，其中7种为不饱和脂肪酸，总不饱和度为92.42%。该油含有必需脂肪酸，即亚油酸（1.34%）、亚麻酸（10.31%）、花生四烯酸（0.60%）以及不同含量的不饱和高级脂肪酸，即二十碳三烯酸（3.39%）、芥酸（3.46%）和神经酸（1.23%）。该油中油酸的含量（72.09%）与血桐中的值相近。
