TITLE:
摘要: 目的:基于三黄泻心汤(简称“泻心汤”)考察黄芩-大黄-黄连不同剂量配伍对黄芩苷和汉黄芩苷溶出的影响,为研究中药复方药味剂量组成配伍的化学机制提供参考。方法:以高效液相色谱法测定黄芩苷、汉黄芩苷含量。固定黄芩剂量(3 g)不变,以大黄和黄连的不同剂量为因素,黄芩苷和汉黄芩苷的溶出率为响应值,设计二因素五水平星点试验,采用响应面法优化黄芩-大黄-黄连最佳剂量配伍,并与经典剂量泻心汤(黄芩3 g、大黄6 g、黄连3 g)比较其中黄芩苷和汉黄芩苷溶出率的变化。结果:黄芩、大黄、黄连的剂量分别为3、1.76、0.17 g时提取液中黄芩苷和汉黄芩苷的总溶出率最高,验证试验中黄芩苷和汉黄芩苷的总溶出率平均为21.89%(RSD=0.46%,n=3),与预测值22.54%的相对误差为2.88%;与经典剂量泻心汤比较,最优配伍剂量黄芩-大黄-黄连提取液中黄芩苷和汉黄芩苷总溶出率提高了47.21%。结论:基于泻心汤的黄芩-大黄-黄连不同剂量配伍对黄芩苷和汉黄芩苷溶出有一定影响,当黄芩、大黄、黄连的剂量分别为3、1.76、0.17 g时其溶出率高于经典剂量。
ABSTRACT: OBJECTIVE: To investigate the effects of different dose compatibility of Scutellaria baicalensis-Rheum palmatum- Coptis chinensis based on Sanhuang Xiexin decoction (shorted for Xiexin decoction) on dissolution rate of baicalin and baicalein, and to provide reference for studying chemical mechanism of TCM compound dose composition compatibility. METHODS: HPLC method was used to determine the contents of baicalin and baicalein. By fixing the dose of S. baicalensis (3 g), using the dose of R. palmatum and C. chinensis as factors, dissolution rate of baicalin and baicalein as response value, two-factor and five-level central composite test was designed. The optimal dose compatibility of S. baicalensis-R. Palmatum-C. chinensis was optimized by response surface method, and compared with the dissolution rate of baicalin and baicalein in classic dose Xiexin decoction (S. baicalensis 3 g, R. Palmatum 6 g, C. chinensis 3 g). RESULTS: When the doses of S. baicalensis, R. palmatum, C. chinensis were 3, 1.76, 0.17 g, total dissolution rate of baicalin and baicalein was the highest in extract. The average total dissolution rate of baicalin and baicalein in validation test was 21.89% (RSD=0.46%, n=3), and the relative error was 2.88% with the predicted value of 22.54%. Compared with the classical dose of Xiexin decoction, the total dissolution rate of baicalin and baicalein in the optimum dose of S. baicalensis-R. Palmatum-C. chinensis in extract was increased by 47.21%. CONCLUSIONS: The different dose compatibility of S. baicalensis-R. Palmatum-C. chinensis based on Xiexin decoction influence the dissolution of baicalin and baicalein to certain extent. When the doses of S. baicalensis, R. palmatum, C. chinensis are 3, 1.76, 0.17 g, dissolution rate of baicalin and baicalein are higher than that of classic dose.
