摘要
目的:测定大黄,郁李仁,枳实,杏仁4种具清热润肠功效中草药微量元素锰铜的含量。方法:硝酸和高氯酸(4+1)混酸分解样品,火焰原子吸收光谱法测定。结果:4种中草药中大黄含锰量高于郁李仁、枳实、杏仁。但郁李仁、枳实、杏仁铜含量均高于大黄。回收率在92.7%～106.3%之间,RSD<5.1%。结论:4种典型的清热润肠中草药中Mn、Cu含量存在差异,可为进一步探讨上述微量元素与药效的关系提供参考数据。
Objective： Determination of rhubarb, Yu Li Ren, bitter orange, almond 4 with Runchang heat effect of manganese content of trace elements in Chinese herbs. Methods： the nitric acid and perchloric acid （4＋1） mixed acid sample digestion, flame atomic absorption spectrometry. Results： in 4 kinds of Chinese herbal medicine rhubarb manganese content higher than Yu Li Ren, citrus, almonds. But Yu Li Ren, bitter orange, almond copper content higher than that of rhubarb. The recovery was 92.7 %-106.3 %, RSD〈5.1%. Conclusions： the 4 kinds of typical heat Runchang herbal medicine in Mn, Cu content existence difference, for further study of the trace elements and efficacy of the relationship to provide reference data.
