电感耦合等离子体原子发射光谱法同时测定镰形棘豆及其炭品中的微量元素

Simultaneous Determination of Trace Elements in Herb and Carbonic Herb of Oxytropis Falcata by ICP-AES

目的:考察镰形棘豆及其炭品微量元素的含量。方法:用电感耦合等离子体发射光谱法(ICP-AES)测定镰形棘豆及其炭品水煎液中砷、锌、铅、钴、镉、铁、锰、铬、镁、铜、钙11种元素的含量并进行比较。结果:镰形棘豆制炭后钙元素的含量显著增加,而其他10种被测元素的含量均有不同程度的减少。结论:镰形棘豆经炒炭后,11种相关元素的煎出量变化很大。对研究其药效物质基础、药理、毒理以及质量控制具有重要的参考意义。

Objective ： To investigate trace elements in herb and carbonic herb of Oxytropis falcata. Methods ： Oxytropis falcata herb and its carbonic herb were extracted in water decocting. Subsequently, the content of eleven elements was determined and compared by Inductively Coupled Plasma Atomic Emission Spectrometry （ICP- AES）. Results：After being processed, the content of calcium in Oxytropis falcata carbonic herb increased, while those of other ten elements investigated all decreased in different degrees. Conclusion ： After being processed, the content of eleven elements in Oxytropis falcata changed markedly.
