| 英文摘要 | 摘要 利用空气-乙炔火焰原子吸收光谱法测定了不同采收时间( 5 月、6 月、7 月、8 月和9 月) 的野生与栽培宽叶羌活药材中微量元素Ca, M g, Fe, Mn, Cu 和Zn 的含量, 应用SPSS16.0 分析软件对结果进行统计分析。结果发现: 羌活药材含有丰富的微量元素, 栽培与野生宽叶羌活药材中微量元素的含量均以Ca元素的含量最高, Cu元素含量最低, 各微量元素的含量从高到低依次是Ca> Mg> Fe> Mn> Zn> Cu。栽培和野生羌活药材六种微量元素含量的季节动态具有明显的规律性。且野生宽叶羌活药材多数微量元素的含量高于人工栽培的含量, 为野生羌活药材的人工引种栽培提供了参考。 Abstract The contents of six trace elements Ca, Mg , Fe, M n, Cu and Zn in the medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii vegetated in different months were determined by flame atomicabsorption spect rometry ( FAAS) with air acetylene flame, and the feature of trace elements contents and their seasonal dynamics were analyzed using SPSS16.0 analysis software. The recovery rate obtained by standard addition method ranged between 96.33% and 105.25%, and the relative standard deviation was 0.84% ~ 2.98%. This showed that the method had good precision and definition. The study indicated that there are abundant microelements in medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii. The contents of Ca are both highest in the medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii, and the contents of Cu element are lowest; the contents order is Ca> Mg> Fe> Mn> Zn> Cu; the seasonal dynamics of Ca, Mg , Fe, Mn, Cu and Zn had obvious regularity in the medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii. It is concluded that the amount of six elements in wild Rhizoma et Radix Notopterygii are more than the cultivated; the data can provide reference for a rtificial cultivation of wild herbs. |
