正交试验优选乳康胶囊提取工艺

目的:研究乳康胶囊提取工艺。方法:以干膏收率、柴胡皂苷a与柴胡皂苷d总量为指标,采用L(934)正交试验优选最佳提取工艺条件。结果:影响提取工艺因素依次为:B第1次加水量>D第2次加水量>A第1次提取时间>C第2次提取时间。最佳工艺条件为:第1次1.5 h,加水8倍量,第2次提取1 h,加水6倍量。结论:该工艺简便、可行,适合于工业生产。

Optimization of the extraction process for Rukang capsule by orthogonal test

Objective： To optimize tile extraction process for Rukang capsule. Methods： The extracting ratio of dry paste, the c, ontent of Saikosaponin a and Saikosaponin d were used as index, the extracting process was optimized hy the orthogonal L9（ 34）. Results： The influencing factors were as follows： B 〉D〉 A〉C （A： tile first extraction time; B： lhe first amount of water; C： the second extraction time; D： the second amount of water）. The -ptimal extraction condition were as follows： the first extraction time was 1.5 h with 8 times of water, the second extraction t：ime was 1 h with 6 times of water. Conclusion： The extraction process is reasonable, practicable and convenient for the industlw production of Rukang capsule.
