| 摘 要： | 采用HNO3-HF-HClO4系统湿法消解后,用ICP-AES法对中草药叶上花中16种微量元素进行了测定,含量从大到小的顺序为：Ca〉K〉Mg〉P〉Si〉Fe〉Na〉Al〉Mn〉Zn〉B〉Cr〉Pb〉Se〉Cu（其中Co未检测出）。该中草药接骨活性很可能与其中Ca、P、Fe、Mn、Zn、Se、Cu等元素有关。测定所用方法16种元素的线性相关系数在0.999 089～1.000 000之间,具有较高的准确度,并可多元素同时测定。

| Abstract: | Sixteen trace elements in chinese herbal medicine Helwingia himalaica were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES) after wet digestion with HNO3-HF-HClO4 digesting system.Their contents are as follows: Ca>K>Mg>P>Si>Fe>Na>Al>Mn>Zn>B>Cr>Pb>Se>Cu>Co.The fracture healing activity of this medicine may be related to its trace elements such as Ca,P,Fe,Mn,Zn,Se,and Cu.This simultaneous determination method for many elements possesses the higher accuracy,which the linear correl... |
