Abstract: For the qualitative and quantitative analysis of contraband drugs for curing obesity -amfe- pramone, a quick and simple method by GC/MS was developed. The method can be applied in forensic and sanitary identification of amfepramone. There is a linear relationship within the ranges of 0.2-1ug. The regress equation: Y=-0.37+2.36X; r=0.993 S=0.088. The recovery is 87.3%.
