Abstract
This study was performed to investigate the contamination levels of heavy metals (such as lead, cadmium, arsenic and mercury) and aflatoxin (such as $B_1$, $B_2$, $G_1$ and $G_2$) in commercial herbs for food and medicine. The concentrations of the heavy metals were measured by the ICP-MS and a mercury analyzer. The aflatoxins were analyzed by a HPLC-florescence coupled with photochemical derivatization. The detection ranges of the lead, cadmium, arsenic and mercury were found to be 0.006~4.088 mg/kg, 0.002~2.150 mg/kg, ND~0.610 mg/kg and ND~0.0139 mg/kg respectively. Among the total samples, the 3 samples (2.6%) were not suitable for the specification of cadmium by the MFDS (Ministry of Food and Drug Safety). The 13 samples of the total 117 samples were aflatoxin positive (11.1%). The amount of aflatoxin $G_1$ was $0.7834{\mu}g/kg$ in the Puerariae Radix and aflatoxin $G_2$ were $0.3517{\mu}g/kg$, $0.4881{\mu}g/kg$ in two samples of the Glycyrrhizae Radix et Rhizoma, respectively. The aflatoxins $B_2$ and $G_1$ were simultaneously detected in the 10 Angelicae Gigantis Radix. The detection ranges of aflatoxins $B_2$ and $G_1$ were $0.2324{\sim}1.0358{\mu}g/kg$ and $0.7552{\sim}1.6545{\mu}g/kg$ respectively in Angelicae Gigantis Radix. The results of the current study suggest that continuous monitoring is needed for the proactive management of commercial herbs for food and medicine safety.
