| 中文摘要: |
| 以琼崖海棠籽为原料,机械压榨法制取琼崖海棠籽油,分析了琼崖海棠籽油的理化指标,并通过气相色谱-质谱( GC - MS)联用分析其脂肪酸组成.结果表明:琼崖海棠籽油的酸值(KOH) 27mg/g,过氧化值1.184 meq/kg,折光指数(n20d)1.489 2,碘值(Ⅰ)83.96 g/100 g,水分及挥发物0.070％,灰分0.029％,皂化值(KOH) 192.3 mg/g,相对密度(d25 4疗)0.934 8；其主要脂肪酸组成是9-十八碳烯酸(27.67％),9,12-十八碳二烯酸(16.78％),9-十八碳烯酸(E)(13.54％),十八碳酸(12.92％),十六碳酸(10.77％),11,14-二十碳二烯酸(7.17％),正十六碳酸(5.24％),十七碳酸(5.13％). |
| 英文摘要: |
| Calophyllum inophyllum seed oil was extracted from the seed of Calophyllum inophyllum by mechanical press,and its physicochemical properties and composition of fatty acids were respectively detected by chemical and GC-MS analysis methods.The results showed that the acid value,peroxide value,refractive index(n20D),iodine value,moisture and volatile matter content,ash content,saponification value and specific gravity(d254) of the oil were 27 mgKOH/g,1.184 meq/kg,1.489 2,83.96 gI/100 g,0.070%,0.029%,192.3 mgKO... |
