Abstract：The effects of different digestives for the fritillaria and atractylodes were compared. Many trace elements in the planted and wild fritillaria and atractylodes were determined by ICP-MS. The results show that the RSD and recovery are better if the planted and wild fritillaria and atractylodes were digested with HNO3-H2O2. Among the many elements determined from the fritillaria and atractylodes, Cu, Zn, Fe, Mg and Mn are the dominant chemicals. The content of Fe was higher in the wild fritillaria and atractylodes than that in the planted fritillaria and atractylodes, while the contents of heavy metal Pb and Cd were lower in the wild fritillaria and atractylodes than those in the planted fritillaria and atractylodes. The wild fritillaria and atractylodes contain Co，which was not determined in the planted fritillaria and atractylodes. The experimental results showed that the detection limits were lower than 0.086 ng·g-1 with low RSD（n=7, 4.85%）for most metal chemicals determined, and the standard recoveries (n=7) ranged from 96.8 to 103.4%.
