| Abstract: | A method for the simultaneous determination of 20 polycyclic aromatic hydrocarbons （PAHs） in black ginseng by GC -MS was developed. The sample was firstly mixed with millipore water and extracted by dichloromethane solution, and then purified by silica gel column. Subsequently, 20 PAHs were quantitative by external standard method. 20 PAHs were separated well by each other, the values of recoveriers and the relative standard deviation （RSD） were in the range of 92. 0% ~ 103.0% and 1.86% ~4. 62%, respectively, and the detection lomits were 10 μg/kg. The results showed that the method was simple, faster, good repeatability, and can satisfy the determination requirements of PAHs residues in black ginseng. |
