摘要
目的:考察酸碱对药附子与甘草在四逆汤中配伍后酸、碱性成分的变化情况。方法:采用高效液相色谱法对附子、甘草单味药提取液、附子甘草对药提取液及全方提取液中乌头生物碱类成分和甘草酸提取量进行了测定。结果: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;随着单药、对药及全方的配伍变化,水煎煮、水煎后离心生物碱提取量逐渐减低,乙醇回流生物碱提取总量变化不明显。对甘草而言,随着单药、对药及全方的配伍变化,水煎煮、水煎后离心,乙醇回流甘草酸提取量均逐渐降低。结论:附子、甘草单煎和乙醇回流、附子、甘草对药煎煮和乙醇回流、四逆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。
Objective： To determine the change pattem of alkaline and acid components of Fuzi and gancao amoung different combinations in Sini Decotion. Method： The contents of aconite alkaloids and glycyrrhizic acid were determined by HPLC in samples of Fuzi extracts, gancao extracts, Fuzi and gancao pair medicines extracts, and extracts of whole recipe. Result： As for Fuzi, monoester aconite alkaloids could be detected in water extracts, and both biester and monoester aconite alkaloids could be detected in eth- anol extracts. The contents of aconite alkaloids were decreased with changes of combinations ： from Fuzi alone to pair medicines, and to whole recipe. The change pattern was more apparent when extracted in water decoction. As for Gancao, the glycyrrhizic acid was lowered from single medicine to pair medicines, and to whole recipe. Conclusion： The contents of alkaline and acid components were changed with different extract methods and different combinations of Fuzi and Gancao.
