Abstract:[Objective]To establish the HSCCC method for separating the gentianine from the alkaline ethanol extracts of gentiana.[Methods]Separation and purification of gentianine by TBE300B HSCCC technology,through the optimization of the solvent system,with n-hexane∶ethyl acetate∶methanol∶water(5∶5∶4∶6)as the solvent system,the upper as stationary phase and the next phase as mobile phase,the rotational speed of the instrument was 850 r/min,the flow rate was 1.5 mL/min,the temperature was 25℃,the detection wavelength was 280 nm.[Results]The gentianine was obtained from the gentian alkaline ethanol extracts by D151 cation exchange resin combining with HSCCC,the content was above 98.8%.[Conclusion]The method is stable and has high results,it could be used to separate gentianine efficiently from alkaline ethanol extract of gentiana.

[目的]探讨神阙散对模型大鼠痛风性关节炎的治疗效果。[方法]分别建立大鼠高尿酸血症和痛风性关节炎模型,全自动生化分析测定大鼠的尿酸、肌酐、尿素氮,探讨神阙散对高尿酸血症的治疗作用;测定肿胀指数变化,同时取各组大鼠的骨组织进行石蜡包埋、苏木精-伊红(HE)染色进行病理学分析,评价神阙散对痛风性关节炎的治疗效果。[结果]两组实验组模型和对照均具有统计学差异,说明造模成功。对高尿酸血症,各给药组和模型对照组相比尿酸、肌酐、尿素氮均具有统计学意义,而神阙散中、高剂量组差异较为显著。对痛风性关节炎,神阙散高剂量组在用药后2 h即开始对痛风性关节炎产生药理作用,对模型大鼠关节炎肿胀指数具有显著降低作用,在用药后4~8 h治疗效果更加显著,其治疗效果与痛风定和秋水仙碱相当。病理结果显示,神阙散低、中、高剂量组均能改善模型大鼠痛风性关节炎的病理结果,且低、中、高剂量组呈现明显的量效关系。中剂量组与痛风定和秋水仙碱疗效相当,高剂量组改善作用优于痛风定和秋水仙碱。[结论]神阙散治疗痛风性关节炎疗效确切。
