The correlation of trace metallic elements in Huidouba and cure diabetes mellitus was established according to results of determination of metal elements in Huidouba by flame atomic absorption spectrometry (FAAS).Huidouba,old tea and dirt of con-necting Huidouba were collected as samples .The samples were extracted with water through boiling and was filtered with gauze ,then the supernatant liquid was digested by nitric acid and perchloric acid and was dissolved in dilute nitric acid and was centrifugated , the centrifugate was used as analytical solution for FAAS .Zinc(Zn),chromium(Cr),selenium(Se),magnesium(Mg),manganese (Mn),cobalt(Co),copper(Cu),nickel(Ni),cadmium(Cd)were determined by FAAS.The results showed that the contents of Cu,Ni,Cd were low in the Huidouba ,however,their values in blood and hair of diabetic patients were higher as compared to nondia -betic patients.In contrast,Zn,Cr,Se,Mg,Mn,Co were high in Huidouba ,their contents in blood and hair of diabetic patients were lower than nondiabetic patients ’s.The levels of essential trace metallic elements ,Zn,Cr,Se,Mg,Mn,Co,Cu,Ni,Cd in Huidouba samples are very beneficial to diabetes mellitus .Huidouba may play a major role in allaying or curing diabetes mellitus .%用火焰原子吸收法测定灰兜巴中微量金属元素的含量，探讨灰兜巴中微量金属元素与治疗糖尿病的相关性。采集灰兜巴以及灰兜巴连接的老茶叶和土壤试样，水煮提取、纱布过滤、静止后取其上层液，用HNO3-HClO4消解，再用稀HNO3溶解，定容，离心，取其上清液，用火焰原子吸收光谱法测定Zn、Cr、Se、Mg、Mn、Co、Cu、Ni和Cd 9种元素的含量。结果表明糖尿病人常偏高的Cu、Ni和Cd元素在灰兜巴中含量相对较低，而糖尿病人常偏低的Zn、Cr、Se、Mg、Mn和Co元素在灰兜巴中的含量相对较高。灰兜巴中Zn、Cr、Se、Mg、Mn、Co、Cu、Ni和Cd等重要微量金属元素的含量很适合糖尿病人，灰兜巴中的微量元素在缓解、治疗糖尿病方面可能发挥了重要作用。
