| 中文摘要: |
| 以传统中药材千金子为原料，在单因素实验基础上，采取响应面法优化千金子油水酶法提取工艺，考察酶解时间、加酶量和酶解温度对千金子油得率的影响，并研究千金子油得率在千金子不同采收期动态变化规律。结果表明，水酶法提取千金子油的最佳工艺条件为：酶解时间2.9 h，加酶量19 mg/g，酶解温度50?℃。在最佳工艺条件下，千金子油得率为33.078%；千金子最佳采收时间为9月中下旬。 |
| 英文摘要: |
| With the traditional Chinese herbal medicine Euphorbia lathyris L. seed as raw material, based on the single factor experiment, the aqueous enzymatic extraction process of oil from Euphorbia lathyris L. seed was optimized by response surface methodology, and the effects of enzymolysis time, dosage of enzyme and enzymolysis temperature on the yield of Euphorbia lathyris L. seed oil were investigated. The dynamic change law of oil from Euphorbia lathyris L. seed in different harvest time was studied. The results showed that the optimal extraction process conditions of Euphorbia lathyris L. seed oil were obtained as follows: enzymolysis time 2.9 h, dosage of cellulase 19 mg/g and enzymolysis temperature 50?℃.Under the optimal conditions, the yield of Euphorbia lathyris L. seed oil was 33.078%. The best harvest time of Euphorbia lathyris L. seed was the mid-late of September. |
