Optimization of Ginger Juice Baking for Rhizoma Coptis by Orthogonal Test / 中国药师

ABSTRACT

Objective:To research the best processing method of ginger juice baking for Rhizoma coptis. Methods:The total con-tent of four alkaloids including berberine hydrochloride determined by HPLC was used as the evaluation index, and an L9(34)orthogo-nal design with three factors including the amount of ginger juice, baking temperature and baking time and variance analysis were ap-plied to study the ginger juice baking technology for Rhizoma coptis. Results:The best processing conditions were as followsRhizoma coptis was soaked with 15% ginger juice, baked at 150℃ for 40 min, and withdrawn to be cool. Conclusion:The optimal ginger juice baking technology for Rhizoma coptis is reasonable, which can be used to guide the standardized production of Rhizoma coptis with gin-ger juice baking.
