| 摘 要： | 采用空气-乙炔火焰原子吸收光谱法对唐吉特铁线莲中的Ca、Zn、Mn、Cu、Fe、Mg、Co7种微量元素进行了含量测定.该方法的加标回收率在98.73％-102.27％之间,相对标准偏差在1.12％-2.10％之间,具有较高的准确度和精确度.唐古特铁线莲中微量元素的含量顺序为Mg＞Ca＞Fe＞Mn＞Zn＞Cu＞Co,且这7种元素与海拔没有线性关系.Mg、Ca、Fe、Mn和Zn含量较为丰富,其平均值分别为273.64、242.85、96.29、4.51、2.68mg/100g.这些研究结果为进一步探讨唐古特铁线莲的药理毒理和药效提供了科学依据. |

| Abstract: | Determination and analysis of trace elements （Ca,Zn,Mn,Cu,Fe,Mg and Co） in Clematis tangutica （Maxim.） Korsh were studied by atomic absorption spectrometry. Recovery and RSD of this method were 98. 73%--102.27% and 1.12%--2.10% respectively,and the method was rapid,reliable and precise. The order of the content in C. tangutica is Mg〉Ca〉Fe〉Mn〉Zn〉Cu〉Co. There was not a relation between altitude and content. The plant C. tangutica was rich in Mg,Ca, Fe,Mn and Zn,and the mean contents of Mg,Ca,Fe,Mn and Zn were 273.64,242. 85,96.29,4.51 and 2.68mg/100g respectively. The results provided theoretical and scientific basis for the research of the effect of C. tangutica herbal medicine. |
