| 中文摘要: |
| 以南天竹种子为原料，采用超声波辅助法提取南天竹籽油，测定了南天竹籽油的理化性质，并用气相色谱-质谱联用（GC-MS）技术分析南天竹籽油的脂肪酸组成。结果表明：南天竹籽油的酸值（KOH）、皂化值（KOH）、过氧化值、碘值（I）、相对密度（20℃）、折光指数（20℃）分别为1.44 mg/g、187.04 mg/g、1.42 mmol/kg、114.51 g/100 g、0.912 7、1.472 6；南天竹籽油中含有13种脂肪酸，主要为亚油酸（60.96%）、棕榈酸（15.55%）、油酸（15.16%）、硬脂酸（4.67%），不饱和脂肪酸含量为77.99%。 |
| 英文摘要: |
| With the seed of Nadina domestica T. as raw material, the seed oil was obtained by ultrasonic-assisted extraction. The physicochemical properties of Nadina domestica T. seed oil were determined and its fatty acid composition was analyzed by GC-MS. The results showed that the acid value, saponification value, peroxide value, iodine value, relative density(20℃) and refractive index(20℃)of Nadina domestica T. seed oil were 1.44 mgKOH/g, 187.04 mgKOH/g, 1.42 mmol/kg, 114.51 gI/100 g, 0.912 7 and 1.472 6, respectively. Thirteen kinds of fatty acids were identified form Nadina domestica T. 〖JP4〗seed oil and the main fatty acids were linoleic acid (60.96%), palmitic acid (15.55%), oleic acid (15.16%)〖JP〗 and stearic acid (4.67%). The content of unsaturated fatty acids was up to 77.99%. |
