The study on determination of trace elements and transference characteristics in the botanic chinese medicinal herb of reducing blood sugar and health food

目的 :对植物性降血糖中药及保健食品中微量元素的含量及溶出特性进行研究 ;方法 :电感耦合等离子体质谱法 (ICP -MS) ;结果 :不同的降血糖中药和保健食品的消解液及冲泡液中锰、铁、锌、钙的含量都很高 ,铜、镍、硒次之 ;其中BCBT茶中镍的溶出率最高达 6 0 2 % ,铜、锌次之 ,分别为 38 7%、35 1%。

objective: studying the determination of trace elements and transference characteristics in the botanic chinese medicinal herb of reducing blood sugar and health food; methods: Inductively Coupled Plasma Mass Spectrometry(ICP-MS); results: in different chinese medicinal herbs of reducing blood sugar and health food ,the contents of Mn?Fe?Zn?Ca are very high, followed by Cu?Ni?Se and the extractive content of Ni in BCBT tea is the highest :60 2% ,Cu Zn is second: 38 7%?35 1%.
