Abstract：The optimum conditions，such as the ratio of fuel gas to combustion-supporting gas，burnerheight，lamp current and band pass，for the determination of trace elements such as calcium，magnesium，cobalt and potassium in flowers were studied by flame atomic absorption spectrophotometry(AAS)． The eｘperimental results showed that Beers law was obeyed in the range of 0-50 μg·mL-1 for Ca，0-80 μg·mL-1for Mg，0-4 μg·mL-1 for Co，and 0-120 μg·mL-1 for K． The correlation coefficients were in the range of 0.99７ 5-0.999 5 under the seleced conditions． Applied to the determination in rose & Chinese rose the method proved to be simple，rapid and selective with satisfactory recovery of 9７％-104％ and relative standard devition of 1.2％-2.3％.
