We have established a method for determination of the trace elements within Rosa roxburghii and Rosa sterilis Fruits in this study. The contents of 15 elements (Al

Zn) were determined by ICP-OES with microwave digestion. The linear ranges of the elements were ranged from 0~10 mg/L with a correlation coefficient more than 0.999 1. The detective limits of the instrument were ranged from 0.000 1~0.006 1 mg/L
precision experiments showed RSD ranged from 0.3%~2.7% and the recoveries of the elements were in the range of 93.3%~107.7%. Such method was used to test the national standard substance Astragalus membranaceus (GBW 10028)
and the result was consistent with the certificate value. Therefore
this method can be used for quickly and accurately measuring trace elements within Rosa roxburghii and Rosa sterilis Fruits.
