酸碱对药大黄与附子在大黄附子汤中配伍的化学研究

目的：考察酸碱对药大黄与附子在大黄附子汤中配伍后酸、碱性成分的变化情况。方法：采用高效液相色谱法对大黄、附子单味药提取液、大黄附子对药提取液及全方提取液中蒽醌类成分和乌头生物碱类成分的提取量进行了测定。结果：对大黄而言，蒽醌类成分的提取量随着单药、对药及全方的配伍变化，水煎滤过、水煎离心逐渐减低，乙醇回流蒽醌类成分的提取总量逐渐升高。水煎煮单药与对药、对药与全方之间的变化趋势均明显。对附子而言，水煎煮只检测到单酯型乌头生物碱，乙醇提取既可检测到单酯型乌头生物碱，又可检测到双酯型乌头生物碱；乌头生物碱的提取量随着单药、对药及全方的配伍变化，水煎滤过、水煎离心逐渐减低，乙醇回流变化不明显；水煎煮单药与对药、对药与全方之间的变化趋势均明显。结论：大黄、附子单煎和乙醇回流、大黄、附子对药煎煮或和乙醇回流、大黄附子汤全方煎煮和乙醇回流，酸、碱性成分的提取量发生有规律的变化。

Compatability chemistry of acid-alkaline pair medicine of Dahuang and Fuzi in Dahuang Fuzi decoction

Objective: To determine the change pattern of alkaline and acid components of Dahuang and Fuzi in different combinatuions. Method: The contents of anthraquinones and aconite alkaloids were determined by HPLC in samples of Dahuang extracts, Fuzi extracts, Dahuang and Fuzi pair medicines extracts, and extracts of whole recipe. Result: As for dahuang, the contents of anthraquinones were decreased with changes of combination: higher in decoctions of Dahuang alone, then in decoctions of pair medicines, and the least in decoctions of whole recipe. As for Fuzi, monoester aconite alkaloids could be detected in water extracts, and both biester and monoester aconite alkaloids could be detected in ethanol extracts. The contents of aconite alkaloids were decreased with changes of combinations: from fuzi alone to pair medicines, and whole recipe. The change pattern was more apparent when extracted in water decoction. Conclusion: The contents of alkaline and acid components were changed with different extract methods and different combinations.
