摘要
[目的]探讨酸枣仁中金属元素与药物药效关系。[方法]以酸枣仁为试材,对样品进行硝化处理,采用火焰原子吸收分光光度计分别测定各标准系列工作液,绘制标准曲线,采用火焰原子分光光度法测定样品溶液中Cr、Cu、Zn、Mn、Ni的含量,将样品稀释10倍后测定K、Ca、Na、Mg、Fe的含量,加10%的La(NO,)3抗干扰以测定K、Na、Ca、Mg的含量。[结果]酸枣仁中含有丰富的金属元素,Mg、Cr、Mn、Ni、Cu、Zn元素含量高于其他中草药。采用火焰原子吸收分光光度法测定酸枣仁的金属元素具有准确度高、操作方便、稳定性好、重现性好的特点,回收率为97.33%～103.15%,能满足中药微量元素检测的需要,可用于同一样品分析多种元素。[结论]该研究为进一步开发和利用中药酸枣仁提供科学依据。
[Objective] The study aimed to discuss the relationship between metal elements in spine date seeds and drug efficacy. [Method] With spine date seeds as the tested materials, they were made for nitrification treatment. The working fluid of each standard series was measured by flame atomic absorption spectrophotometer and the standard curve was drawn. The contents of Cr,Cu,Zn,Mn,Ni of sample solution were determined by flame atomic absorption spectrophotometry, the contents of K, Ca, Na, Mg, Fe were determined with samples solution diluted by 10 times ,and the contents of K,Na, Ca, Mg were determined by adding 10% of La（ NO3 ）3 for anti-interference. [ Result ] Metal elements were rich in spine date seeds,and the contents of Mg, Cr, Mn,Ni,Cu,Zn were higher than that of other Chinese herbal medicines. Using flame atomic absorption spectrophotometry to determine metal elements in spine date seeds had features of high accuracy,convenient operation,good stability and reproducibility and the recovery rate was 97.33% - 103.15% ,which could meet the needs of detection of trace elements in traditional Chinese medicines and could be used to analyze the multi-element in the same sample. [ Conclusion] The study provided a scientific basis for the further development and use of spine date seeds.
