RESUMO
Objective:To research the best processing method for Bupleurum chinense DC.by orthogonal tests.Methods:With the contents of saikosaponin a and saikosaponin d as the indices,the L9(34) orthogonal table was used to study three factors including the amount of wheat bran,pot temperature before heating and processing time.The orthogonal design was applied to study the processing technology of Bupleurum chinense DC.fried with wheat bran.Results:The best processing method was as follows:100 g Bupleurum chinense DC.was mixed with 10 g wheat bran and fried at 290 ℃ for 80 seconds.Conclusion:The optimized processing technology is reasonable,reliable and highly reproducible,which provide reference for the processing of Bupleurum chinense DC.with wheat bran.
RESUMO
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processing conditions were as follows:Rhizoma coptis was soaked with 15% ginger juice, baked at 150℃ for 40 min, and withdrawn to be cool.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.
