Abstract
Microwave digestion and soaking were used to extract the samples of traditional Chinese herbal medicine (Huai chrysanthemum,wolfberry,Siraitia grosvenorii and American ginseng).The contents of Ca,Fe,Zn,Cu and Mn in the four traditional Chinese herbal medicines and their extracts were determined by flame atomic absorption spectrometry.The recovery experiments of Ca,Fe and Zn were carried out to verify the accuracy of the determination method.The results showed that the contents of five microelements in four kinds of traditional Chinese herbal medicine samples were different.The contents were as follows:Ca > Fe > Zn > Mn > Cu in chrysanthemum; Ca > Fe > Zn > Cu > Mn in wolfberry,Siraitia grosvenorii and American ginseng; the contents of five micro elements in Huai chrysanthemum were higher than those in the other three kinds of traditional Chinese herbal medicine,and the content of Ca element was as high as 3.097 5 mg/g.And there was no direct relationship between the leaching rate of microelements and the mass concentration of microelements in the four traditional Chinese herbal medicines sample.The recoveries of Ca,Fe and Zn were between 81% and 97%,showing that the accuracy of the determination method was high.
