| 摘要: |
| 高压密封消化罐消解法将晒干的广西巴豆的根、茎、叶、种子壳及种子进行消解,ICP-AES同时测定其中K、Cu、Fe、Zn、Ca、Mg、Mn、Al、Sr、Na元素的含量,该方法的加标回收率在90.2%～114%之间,RSD<5.57%,测定结果符合分析要求。结果显示,Mn、Mg、Ca在巴豆叶中含量最高,种子中则富含Zn、Cu、K、Na,在种子壳中Sr的含量最高,根中含量最高的是Al,而K、Cu、Fe、Zn、Ca、Mg、Mn、Al、Sr、Na十种元素在茎中分布均匀。 |

| Abstract: |
| The roots,stems,leaves,shells and seeds of Croton tiglium from Guangxi were digestion by high pressure digestion jar,The microelements in different parts of C.tiglium were determined by ICP-AES. The recovery rates of the methed were 90.2%-114%,the relative standard deviations were less than 5.57%,the results were satisfying. The results showed that the leaves of croton tiglium had move Mn,Mg,Ca,the seeds had more Zn,Cu,K,Na,the content of Sr,Al in the shells,roots were most respectively. Ten elements( K,Cu,Fe,Zn,Ca,Mg,Mn,Al,Sr,Na)could be found in every parts of croton tiglium. |
