中药膏药是一种古老传统剂型。按传统工艺,需经长时间高温加热(320℃)。作者应用薄层层析、气相、红外等方法对某一传统膏药成分作了分析。结果表明,药材与油经高温加热后,有效成分破坏很多。建议对药膏炼制工艺进行改进。
Traditional Chinese medicine plaster is an ancient traditional dosage form. According to the traditional process, high temperature heating (320°C) is required for a long time. The author used thin-layer chromatography, gas phase, infrared and other methods to analyze the composition of a traditional plaster. The results showed that after the medicinal materials and oil were heated at high temperatures, the active ingredients were destroyed. It is recommended that the ointment refining process be improved.
