目的:考察黄蒿消炎颗粒中青蒿与川芎挥发油的提取及包合条件。方法:采用正交试验,以挥发油体积为提取工艺的指标,以包合物收得率和挥发油包合率为包合工艺的评价指标。结果:挥发油最佳提取工艺为:加10倍量的水不浸泡,提取8h;挥发油包合的最佳工艺为:采用饱和水溶液法,-βCD与挥发油比例为6∶1,在50℃下包合90min。结论:黄蒿消炎颗粒的挥发油提取及包合工艺合理可行。
OBJECTIVE: To investigate the extraction and inclusion conditions of the essential oil of Artemisia annua L. and Ligusticum chuanxiong Hort in Artemisia annua Xiao Yan. Methods: The orthogonal test was used to determine the volume of volatile oil as the index of extraction process. The recovery rate of inclusion compound and inclusion rate of volatile oil were taken as the evaluation indexes of inclusion process. Results: The optimum extraction process of volatile oil was as follows: 10 times the amount of water is not soaked, extraction 8h; Volatile oil inclusion process: using saturated aqueous solution, β-CD and volatile oil ratio of 6: 1, Combined 90min. Conclusion: The extraction and inclusion technology of volatile oil of artemisia annua Hsiao-Yan granules is reasonable and feasible.
