RESUMO
The aim of the present study was to optimize the shaping technology of the traditional herbal formula Genhuang dispersible tablets, and also establish a method for content determination. The optimal formulation of Genhuang dispersible tablets was determined based on the results of single factor test and orthogonal design test. The disintegration was used as the main study indicator. The proportion of each adjuvant in the optimal formulation consisted of 40% MCC as bulking agent, 15% PVPP and 7% L-HPC as disintegrant, ethanol as adhesive, CSD as lubricant, preparing the dispersible tablets with wet granulation. The content of baicalin in Genhuang dispersible tablets was determined by RP-HPLC method, the C[18] column [150×4.6 mm, 10micro m] was used, the mobile phase was methanolwater- phosphoric acid [47: 53: 0.2] with the flow rate of 1mL/min, the detection wavelength was at 280 nm and the column temperature was 30 . The prepared dispersible tablets could be totally disintegrated within three minutes and in accordance with the standard of the Chinese pharmacopoeia. In conclusion, the formulation was suitable for Genhuang dispersible tablets, and the determination method was simple, sensitive and accurate. Therefore, the Genhuang dispersible tablets can be used for industrial production and effectively controlled
