Abstract:
Objective Ganglouyuchuang lotion was used to dress the wound for Anal fistula in Crohn's disease, control inflammation and promote wound healing.This paper studied the extraction techonology of ganglouyuchuang lotion.Methods Four factors of ganglouyuchuang lotion, including volume of water, extraction time, extraction times and liquid ratio, were studied by the orthogonal test, and three levels were selected for each factor.The content of sodium danshensu, the active component contained in Chinese herbal medicine, was regarded as evaluating indicator, and the content of Danshensu Sodium was determined by HPLC.The water extraction and alcohol precipitation technology of ganglouyuchuang lotion was optimized according to the results of measurement.Results The optimum extraction technology of ganglouyuchuang lotion was as follows: four herbs, including Salvia miltiorrhiza, Radix Astragali, Radix sanguisorbae and Senecio were added with8 times amount of water overnight and decocted 3 times with 2 h, 1.5 h, and 1.5 h respectively, and then the extraction was concentrated to the ratio of herbs and concentrate of 1∶1.5.The results showed that the contents of Danshensu Sodium from the three examples were 0.520, 0.498, and 0.521 mg/mL, and the RSD were 0.34%, 0.41%, and 0.29%.Conclusion The optimum extraction technology is feasible and applicable for the preparation of ganglouyuchuang lotion.
