| 摘 要： | 采用微波消解-电感耦合等离子体-发射光谱法(ICP-OES)测定了中药材马蔺不同部位中Ca,Mg,Fe,Zn,Cu等21种元素的含量。结果表明,各元素线性关系良好,相关系数r≥0.9980;加标回收率在96.4%—103.1%之间,RSD<4.70%。马蔺的根、种子和叶中含量最多的3种元素的排序均为Ca>Mg>Fe。不同部位相较而言,元素Cr,Zn,Cu,Tl,Sb和Cd在种子中含量最多;Ca,Mg,Sr,Ni,Mo,Li和Pb在叶中含量最多;Fe,Mn,V和Ti则在根中含量最高,Co元素只在根中检出。实验结果可为马蔺中所含元素与其药效之间的关系提供一定的科学依据。 |

| Abstract: | The contents of 21 elements in different parts of a traditional Chinese herbal medicine Iris lactea Pall.var.chinensis(Fisch.) Koidz were determined by inductively coupled plasma optical emission spectrometry(ICP-OES) with microwave digestion.The linear relationship of various elements were good(r≥0.9980),and the recoveries were in the range of 96.4%—103.1% with RSD less than 4.70%.The contents orders of the most 3 elements in root,seed and leaves of Iris lactea Pall.var.chinensis(Fisch.) Koidz were all Ca>Mg>Fe.Contrarily speaking from different part,the contents of elements including Cr,Zn,Cu,Tl,Sb and Cd in seed were most,but that of Ca,Mg,Sr,Ni,Mo,Li and Pb in the leaves were most,then the contents of Fe,Mn,V and Ti in the root were most,and Co was only detected in the root.The results can provide the centain scientific basis for investigation of the relationship between all elements in Iris lactea Pall.var.chinensis(Fisch.) Koidz and their pesticide effects. |
