摘要
对蕤仁油的理化性质及脂肪酸组成进行分析,结果表明,蕤仁粗脂肪含量42.9%,蕤仁油的酸值、碘值、过氧化值及皂化值分别为3.77mgKOH/g,133.6g/100g,10.6mmol/kg,209.5mgKOH/g。蕤仁油主要由9种脂肪酸组成,饱和脂肪酸以棕榈酸(7.03%)为主,其次是硬脂酸(2.17%)和花生酸(1.32%);不饱和脂肪酸中亚油酸(51.7%)和油酸(36.6%)含量较高;蕤仁油Sn-2位脂肪酸主要由亚油酸(60.0%)和油酸(37.2%)组成。蕤仁油甘三酯组成中,β-OLL含量最高,为20.71%。
The physicochemical properties and the fatty acid composition of the Nux Prinsepiae Uniflorae oil were mainly analyzed. The content of the crude fat of the Nux Prinsepiae Uniflorae was 42.9%. The acid value, iodine value, peroxide value and saponification value of Nux Prinsepiae Uniflorae oil were 3.77 mgKOH/g, 133.6 g/100 g, 10.6 mmol/kg and 209.5 mgKOH/g, respectively. Nine kinds of fatty acids were found in Nux Prinsepiae Uniflorae oil. The saturated fatty acid were maily palmitic acid(7.03%), stearic acid(2.17%) and arachidic acid (1.32%). The unsaturated fatty acids were mainly composed of linoleic acid(51.7.6%) and oleic acid(36.6%). The Sn-2 fatty acids were maily linoleic acid (60.0%) and oleic acid(37.2%). The fatty acid distribution of Nux Prinsepiae Uniflorae oil was also determined, and the highest content of β-OLL was up to 20.71%.
