甘草制吴茱萸炮制研究

目的:通过正交设计建立甘草制吴茱萸的炮制工艺,并进行质量标准研究、毒理研究和药效学研究。方法:以吴茱萸胺、吴茱萸次碱为指标进行炮制工艺的优化,以RP-HPLC测定吴茱萸胺和吴茱萸次碱的含量,并进行吴茱萸生品和甘草制品小鼠的急性毒性实验和药效学试验。结果:甘草制吴茱萸的炮制工艺,甘草汁用量以6倍于药材的甘草溶液进行闷润,以低于230℃炒制至干。毒性及药效研究:吴茱萸生品和甘草制品以40(g饮片).(kg体重)^-1,b.w给小鼠一次性灌胃给药后观察7 d,各给药组的动物均未见明显异常;给小鼠灌胃给予0.6 g生药.kg^-1(临床等效剂量)的吴茱萸饮片产品(生品、甘草制品)后,均可明显升高小鼠热板痛阈值;明显减少由冰醋酸诱导的小鼠腹膜刺激性扭体反应次数,对小鼠扭体反应次数,对小鼠扭体反应的潜伏期也有一定延长作用。结论:生品吴茱萸和甘草制吴茱萸的毒性较低,甘草制吴茱萸具有镇痛作用。

Study of liquorice processing fructus

OBJECTIVE: To establish the processing method of fructus evodiae and its standard for quality control, toxicity aspects and pharmacodynamics were carried out at the same time. METHOD: In the studies of processing techniques, the optimized technical parameters were determined by the contents of evodiamine and evodine. And the acute toxicity and pharmacodynamics were studied by rats. RESULT: The process was that the liquorice-processed fructus evodiae was wetted by liquorice decoction by sixth of raw fructus evodiae (V/W) and fried below 230 degrees C. The method of detecting the contents of evodiamine and evodine was that Alltima ODS C18 (4.6 mm x 250 mm, 5 microm); mobile phase acetonitrile-water-tetrahydrofuran-phosphoric acid (51:48: 1: 0.05); column temperature 25 degrees C; mobile rate 0.8 mL x min(-1); wave length 225 nm. The toxicity experimentation show that rats didnt show any notable changes after affused the raw material and the processed fructus evodiae's decotion 40 g x kg(-1) b. w. at one time seven days constantly. The analgesic effect was observed after 0.6 g (material) x kg(-1) (weight) b. w. CONCLUSION: The toxicity of the raw material and the processed one were low and the liquorice-processed fructus evodia analgesic effect was good.
