| 摘 要： | 目的:考察赭石炮制前后与药理作用相关的11种元素的含量变化,以探讨赭石的炮制机理。方法:用电感耦合等离子体发射光谱法(ICP)测定生、煅赭石水煎液中11种元素的含量并进行比较。结果:赭石炮制后As元素的含量大大降低,其它10种被测元素的含量均有不同程度的增加。结论:赭石经煅淬后,11种相关元素的煎出量变化很大。实验结果为探讨赭石炮制机理提供了一定的依据。

| Abstract: | Objective:To investigate the changes of eleven elements in curde and calcined ochre,approaching the process mechanism of ochre.Methods: The crude and calcined ochre were extracted in water decocting.Subsequently,the content of eleven elements was determined by inductively coupled plasma emission spectrometry(ICP)and compared.Results:After being calcined,the content of As in ochre decreased sharply,while the content of the other ten elements investigated all increased at different degrees.Conclusion: After being calcined,the content of eleven elements in ochre changed largely.This paper could provide basis for the process mechanism. |
