目的:优选黄连的最佳姜炙工艺。方法:以盐酸小檗碱等4种生物碱的总含量为考察指标,用L_9(3~4)正交设计表,选择生姜用量、烘制温度及烘制时间3个因素,采用方差分析对黄连的姜炙工艺优选。结果:黄连的最佳姜炙工艺为:生黄连加15%姜汁润透后,在150℃下烘制40 min,取出,晾凉。结论:优选出的姜炙工艺设计合理、结果可靠,为规范姜炙黄连生产提供了理论依据。 Objective: To optimize the best ginger rhizome process. Methods: The total content of four alkaloids, such as berberine hydrochloride, was investigated. The orthogonal design of L_9 (3-4) was used to select the amount of ginger, baking temperature and drying time. The variance analysis Coptis ginger Sunburn preferred process. Results: Coptis best ginger Sunburn process: raw Huanglian plus 15% ginger juice Run through, baked at 150 ℃ 40 min, remove and let cool. Conclusion: The optimized ginger Sunburn process design is reasonable and the results are reliable, which provides a theoretical basis for regulating ginger Sunburn Coptis production.
