A microwave-assisted digestion method for pretreatment of biomaterial,Fructus Lycii,has been studied in this paper.The influence factors and test condition affecting digestion results were discussed,and the factors included the sort of mixed acid,the volume of mixed acid,the power of microwave oven and microwave digestion program.The contents of nine elements in Fructus Lycii were determined by ICP-AES.The digestion results were proved to be reliable by adding standard recovery experiment to the process.It was showed that microwave technique for digestion of biomaterial was simple and safe to operate,quickly accessible and safe for operators.
