The sample of Seabuckthorn vitamin P powder was digested with microwave, and contents of Fe, Se, Zn, K, Na, Ca, Mg, Cu, Mn, Pb, As, Hg, and Cd in the sample were determined by ICP-MS. The polyatomic ion effect was eliminated with dynamic reaction cell technique. This method is simple, quick, precise, and sensitive. Recoveries ratio were in the range of 96.2%-101.8%, and the RSD was less than 3%.
