中文摘要	eight trace elements such as ca, cu, fe, mn, zn, k, mg and na in twelve kinds of flower medicines were determined by flame-atomic absorption spectrometry with air-acetylene flame. the flower medicines include pueraria lobata ohwi., gomphrena globosa l., chrysanthemum morifolium ramat., prunus persica (l.) batsch., canna indica l., pyrus bretschneideri rehd p. spp, rosa chinensis jacq., celosia cristata l., sophora japonica l., saussurea medusa maxim., iris lactea var. chinensis (fisch.) koidz. and gentiana straminea maxim.. all of the flowers were commonly used in tibetan medicines. three kinds of the flowers were bought in the market and the others were picked in qinghai province. these flower medicines were selected, dried and powdered, 4.000 g was weighed accurately with analytical balance, and five portions were used for each kind of sample. the content of eight trace elements in these flower medicines was determined and the difference in the content was observed. the recovery rate obtained by the standard addition method was between 96.76% and 102.93%, and the rsd was between 1.13% and 3.46%, so the accuracy of the method was better and the precision of the method was good. the results of the experiment indicated that the contents of the eight trace elements were rich in the twelve kinds of flower medicines, and the content of three trace elements including k, mg, na were more than other trace elements in the twelve flower medicines. there were considerable differences in the content of the eight trace elements in different flower medicines and there were more trace elements in saussure medusa maxim., iris lactea var. chinensis (fisch.) koidz., canna indica l. and celosia cristata l. and less trace elements in sophora japonica l. and gentiana straminea maxim.. the data of the experiment could provide an accurate and credible evidence for the reasonable medicinal use and deeper exploitation of these flower medicines.
