| 摘 要： | 采用索氏提取法、石油醚浸泡法以及超声波提取法提取金花葵籽油,并对3种提取方法的含油率进行比较。利用GC-MS方法对金花葵籽油中不饱和脂肪酸的含量进行测定,并对气相的条件进行了优化。测定结果表明金花葵籽油含有亚油酸32.35%,油酸43.89%,棕榈油酸0.40%,不饱和脂肪酸占76.64%,含量较丰富。 |

| Abstract: | The oil was extracted from Hibiscus manihot seed using Soxhlet extraction method,petroleum ether soak method and ultrasonic extraction method.Oil extraction rate of three extraction methods were compared.The unsaturated fatty acid compositions of seed oil were analyzed by GC/MS and Gas Chromatographic condition was optimized.The results showed that the content of linoleic acid,oleic acid and palmitoleic acid were 32.35 %,43.89 % and 0.40 % respectively and unsaturated fatty acids were 76.64 %. |
| Keywords: | GC-MS unsaturated fatty acids Soxhlet extraction method ultrasonic extraction method |
