Abstract:
Objective To establish the best technological condition of Guanzhoukang Oral Liquid. Method Based on the evaluation marker of extraction amount and gentiopicroside content in prescription, the factors influencing the effect of water decoction and alcohol reflux procedure were selected by orthogonal design. Results The best technological condition of Guanzhoukang Oral Liquid should be as follows:radix gentianae, radix isatidis and radix scutellariae contained in prescription were extracted by alcohol in which the concentration was 65%, 8 times of total amount of material herb, extracted 3 times, 1 h for each time. The left material herbs were extracted by water decoction in which amount was 12 times of total amount of material herb, soaked for half hour and decocted 3 times, 1 h for each time. Conclusion The result provides experimental basis for the preparation technology of Guanzhoukan Oral Liquid.
