一、提取方法取苦参1000g,切细。用温水浸泡3～4h。共煎三次,每次煎1h,共得煎液1500ml。滤过,浓缩。加95%乙醇使含醇量达70%。冰箱内静置24h。倾取上清液,减压回收乙醇,得总提取物100ml,备用。酸枣仁1000g,同苦参提取法。复方苦参1ml相当于苦参和酸枣仁原生药各5g;酸枣仁1ml相当于原生药10g。复方苦参成人用量为2ml。本品临用前用蒸馏水稀释5倍供动物实验用。二、实验方法与结果1.对异戊巴比妥纳阈下催眠剂量的协同作用:取小鼠30只,随机分为三组,给药组按10g/kg剂量腹腔注射。结果表明,无论酸枣仁组还是复方苦参组,对异戊巴比妥 First, the extraction method Take matrine 1000g, shredded. Soak in warm water for 3~4h. A total of three fried, each fried 1h, a total of 1500ml decoction. Filter and concentrate. Plus 95% ethanol to 70% alcohol content. Keep in the refrigerator for 24h. The supernatant was decanted, and the ethanol was recovered under reduced pressure to obtain 100 ml of the total extract. Suanzaoren 1000g, with Sophora extract method. Compound Sophora flavescens 1ml is equivalent to 5g each of the raw materials of Sophora flavescens and Suanzaoren, and 1ml of Suanzaoren is equivalent to 10g of the original drug. The amount of adult compound Sophora flavescens is 2ml. This product is diluted 5 times with distilled water before use for animal experiments. II. Experimental methods and results 1. Synergistic effects of hypotonic hypnotic doses of isoproxol: Thirty mice were randomly divided into three groups and the administration group was given an intraperitoneal injection of 10 g/kg. The results showed that whether Suanzaoren group or compound Sophora flavescens group, for isoprenaline
