用糖心产精国品免费入口*完整版法处理样品,用硝酸-过氧化氢(4+1)混合溶液作为消解剂进行糖心产精国品免费入口*完整版,糖心产精国品免费入口*完整版测定了中药女贞子中钙、镁、钾、钠、铁、锶、锰、铜和锌元素含量.9种元素检出限(3S/N)在0.000 6~0.024 8 mg·L-1之间,回收率在93.0%~107.3%之间,相对标准偏差(n=10)在0.86%~4.39%之间.试验结果表明:女贞子中钾、钙、镁、铁、钠、锌、锰、铜和锶质量分数分别为16 940,1 790,1 640,467.8,116.0,24.5,15.0,9.6,1.9 μg·g-1,锌与铜含量的比值为2.55.由此可见,女贞子中钙、镁、钾元素含量丰富,铁含量也较高.为探讨中药糖心产精国品免费入口*完整版种类及含量与治疗心血管疾病的关系等提供有用数据.

Flame atomic absorption spectrometry was applied to the determination of 9 metal elements,i.e.,Ca,Mg,K,Na,Fe,Sr,Mn,Cu and Zn,in the traditional Chinese medicine of Fructus ligustri lucidi.The sample was digested with a mixture of HNO3 and H2O2 (4+1,by vol.) in a microwave digestor.The sample solution was diluted to 50.0 mL,and used for FAAS determination.Detection limits (3S/N) found for the 9 elements were in the range of 0.000 6 to 0.024 8 mg·L-1.Tests for recovery and precision were made by standard addition method,and values of recovery and RSD′s (n=10) found were in ranges of 93.0%-107.3% and 0.86%-4.39% respectively.Amounts of the 9 elements found in the medicine sample were as follows:K 16 940 μg·g-1,Ca 1 790 μg·g-1,Mg 1 640 μg·g-1,Fe 467.8 μg·g-1,Na 116.0 μg·g-1,Zn 24.5 μg·g-1,Mn 15.0 μg·g-1,Cu 9.6 μg·g-1,Sr 1.9 μg·g-1 and the ratio of Zn/Cu attained to a value of 2.55.These data were useful in going further into the mechanism of therapeutic effect of the medicine in treating cardiocerebral vascular diseases.
