| 摘 要： | 将采收于青果期、黄果期、黑果期及储存1a、2a的麻疯树种子提油,测定其理化性质,并利用GC-MS分析这5个不同时期的种子所提取的麻疯树种子油成分。结果表明:5个油样的水分、酸值、出油率有较大差异,主要化学成分、碘值、皂化值差异不大。青果的出油率为13.13%,水分为0.66%,酸值为69.21,不饱和脂肪酸含量最低。新采成熟果实的出油率为54.64%,水分为0.36%,酸值为1.51,不饱和脂肪酸含量也相对较高。因此,新采的成熟果实较为适合作生物柴油的原料。

| Abstract: | The oils extracted from Jatropha curcas seeds at different ripening and storage stages were analyzed by GC-MS. The physicochemical characteristics of the seed oils were also determined. The chemical composition of the seed oils, iodine value, and saponification value were similar, whereas the yields, acid values and water content of the seed oils showed obvious differences. The yield, water content and acid value of the seed oil from the green fruit were 13.31%, 0.66% and 69.21, respectively, while those from the fresh ripe fruits were 54.64%, 0.36%, and 1.51, respectively. The content of unsaturated fatty acids in the seed oils of green fruits was lowest. Therefore, the fresh ripe fruits are more preferable for raw material of Bio-diesel oil. |
