目的:为将疏肝利胆汤制成颗粒剂,考察其中挥发油的最佳提取工艺。方法:取处方中含挥发油成分的枳实、木香、郁金三味药,选定加水量,浸泡时间和蒸馏时间作为考察的三个因素,各取三个水平,以挥发油得率为考察指标,进行正交试验和方差分析。结果:最终较优方案为加6倍水,浸泡30 min,蒸馏6 h。结论:该提取工艺稳定、可行,为生产工艺的筛选提供了可行方案。
OBJECTIVE: To study the optimal extraction process of volatile oil from Shugan Lidan decoction. Methods: Take the recipe containing volatile oil ingredients Zhishi, wood, tulip shamisen medicine, the selected amount of water, soaking time and distillation time as the study of the three factors, each taking three levels, the rate of volatile oil as the indicator , Conducted orthogonal test and analysis of variance. Results: The final optimal solution was adding 6 times of water, soaking for 30 minutes and distilling for 6 hours. Conclusion: The extraction process is stable and feasible, which provides a feasible solution for the screening of production technology.
