Analgesic Effect of Different Extraction Process of Taohong Siwu Decoction and Its separating Prescription / 中药新药与临床药理

ABSTRACT

Objective To compare the analgesic effect of Semen Persicae (SP, Taoren), Flos Carthami (FC, Honghua), Siwu Decoction (SD) and Tao Hong Siwu Decoction (THSD) in dysmenorrhea model and the acetic-acid-induced pain model. Methods The dysmenorrhea model and the acetic-acid-induced pain model were established, and the pain threshold was compared in different mice models. Results On dysmenorrheal model, the analgesic effect of water extract supernatant and ethanol suspension of FC, SP polysaccharide, water extract supernatant and ethanol extract of SD, SD and THSD polysaccharide differed from that of blank control. On acetic-acid-induced pain model, the analgesic effect of water extract supernatant and ethanol suspension of FC, FC polysaccharide, ethanol extract of SP, SP polysaccharide, SP+ FC water extract, SP+ FC ethanol extract, SP+ FC polysaccharide, SD ethanol extract, SD polysaccharide, THSD water extract and ethanol extract, and THSD polysaccharide differed from that of blank control. Conclusion FC water extract and ethanol extract, SP ethanol extract, THSD polysaccharide, SD ethanol extract and SD polysaccharide have the best analgesic action, and then come with THSD water extract and ethanol extract, SP + FC ethanol extract, and SP + FC polysaccharide.
