Objective To optimize the drying process of Compound Banlangen Liyan Granules thick extract.Methods HPLC method was used to simultaneously determine the contents of six index components and characteristic map compared with the original solution in Compound Banlangen Liyan Granules thick extract and dry cream powder.Single factor and orthogonal test methods were used to optimize the drying process of the thick extract,which took the comprehensive score of the similarity of characteristic maps,the sum of the converted peak area ratios of 19 characteristic peaks and the average transfer rate of 6 components as indicators to investigate the effects of atmospheric drying, vacuum drying and spray drying on the quality of dry paste powder.Results The optimum process parameters of the three drying methods were atmospheric drying temperature 60 ℃;vacuum drying vacuum degree-0.085^-0.095 MPa, temperature 50 ℃;spray drying spray air flow 50 m^3/h, the intake air temperature 145 ℃, and the liquid feeding rate 30%. The comprehensive scores of the optimal parameters of the three drying methods were 96.20,100.00 and 100.07,respectively.Conclusion The drying process of the Compound Banlangen Liyan Granules thick extract can be vacuum drying or spray drying.The optimized drying process is stable and feasible, and the parameters are scientific and reasonable, providing a basis for the thick extract drying method of the traditional Chinese medicine preparation.
