复方土牛膝合剂浸膏质量标准研究

目的：研究复方土牛膝合剂浸膏质量标准，以控制其质量。方法：对复方土牛膝合剂浸膏君药、臣药进行化学鉴别、薄层鉴别和荧光鉴别、相对密度检查、总固体物质量测定、干燥失重检查和水中不溶物检查等。结果：君药土牛膝的化学试剂鉴别显墨绿色，君药土牛膝的薄层鉴别中，供试品在与对照药材色谱相应的位置显3个相同的蓝色斑点。臣药板蓝根的荧光鉴别显黄色荧光。复方土牛膝合剂浸膏的相对密度应不低于1．18718g／mL，含总固体不超过39．43％（g／g），干燥减失重量不超过60．07％（g／g），水中不溶物不超过3.20％（g／g）。结论：此检查操作可行，可用来控制复方土牛膝合剂浸膏质量。

STUDY ON THE QUALITY STANDARDS FOR THE EXTRACTUM OF COMPOUND TWOTOOTH ACHYRANTHES ROOT MIXTURE

OBJECTION: To control the quality for the extractum of Compound Twotooth Achyranthes Root mixture by studying on the quality standards. METHODS: Study on chemical identification, thin - layer chromatography (TLC), fluorescent identification, relative density, the weight of total solid substance, the loss weight of dryness, the weight of indissolvable substance in water etc. RESULTS: The chemical identification of the extractum of Compound Twotooth Achyanthes Root mixture shows black - green and the extractum of Compound Twotooth Achyranthes Root mixture shows three same blue spots with reference shows yellow fluorescence. The relative density is not less than 1.18718g/ml, and the weight of total solid substance is not more than 39.43% (g/g), and the loss weight of dryness is not more than 60.07% (g/g), and the weight of indissolvable substance in water is not more than 3.20%% (g/g). CONCLUSION: The operation can be used to control the quality of the extractum of Compound Twotooth Achyranthes Root mixture.
