Abstract

The increase in the consumption of herb medicines have made their use a public health problem due to the potential fungal contamination and the risk of the presence of my cot ox ins. 360 samples of herb medicines were evaluated for the aflatoxin contamination. The natural occurrence of aflatoxins in these samples were determined using immunoaffinity column clean up and high performance liquid chromatography (HPLC) with post-column derivatization. For samples analyzed, mean levels (incidence) of AFB1, AFB2, AFG1 and AFG2 in positive samples were $1.4\;{\mu}g/kg$(46.4%), $0.4\;{\mu}g/kg$(25.4%), $1.1\;{\mu}g/kg$(37.8%) and $0.9\;{\mu}g/kg$(24.3%), respectively. Recoveries of the full analytical procedure were 71.7~99.7% for AFB1, 88.1~99.2% for AFB2, 82.8~95.5% for AFG1 and 77.9~90.0% for AFG2. The excess cancer risk estimated using the cancer potency of aflatoxin B1 (7 $(mg/kg/day)^{-1}$ for $HBsAg^-$ and 230 $(mg/kg/day)^{-1}$ for $HBsAg^+$) were $1.30{\times}10^{-5}{\sim}1.22{\times}10^{-7}$ for hepatits B surface antigen negative ($HBsAg^-$) and $3.31{\times}10^{-4}{\sim}3.12{\times}10^{-6}$ for hepatits B surface antigen positive ($HBsAg^+$) respectively. In conclusion, although the contamination levels of samples used in the study were low, further actions are also required to undertake a program of herbal surveys in order to access mycotoxin contamination overall so that the safety of public will be protected.

서울시내에서 2010년 중 유통된 한약규격품 19종 (360건)을 구입하여 면역친화성칼럼과 유도화장치가 부착된 액체크로마토그래프를 이용하여 아플라톡신의 함량을 분석 하였다. 그 결과 전체 시료 360건 중 아플라톡선 B1은 168건 (46.4%), 아플라톡신 B2는 92건 (25.4%), 아플라톡신 G1은 137건 (37.8%) 그리고 아플라톡신 G2는 88건 (24.3%) 검출되었고, 검출량은 아플라톡신 B1 $1.4{\pm}1.8\;{\mu}g/kg$, 아플라톡신 B2는 $0.4{\pm}1.1\;{\mu}g/kg$, 아플라톡신 G1은 $1.1{\pm}5.0\;{\mu}g/kg$ 그리고 아플라톡신 G2는 $0.9{\pm}3.4\;{\mu}g/kg$이었으며, 백자인과 빈랑자를 제외한 모든 시료에서 아플라톡선 B1 허용 기준 ($10\;{\mu}g/kg$ 이하)에 적합하였다. 위해성 평가 결과 전체 시료의 초과발암위해도는 B형 간염 비보균자의 경우는 $1.30{\times}10^{-5}{\sim}1.22{\times}10^{-7}$이었고, B형 간염보균자의 경우는 $3.31{\times}10^{-4}{\sim}3.12{\times}10^{-6}$의 범위이었다. 본 연구의 대부분 시료에서 아플라톡신의 오염량은 적은 것으로 평가되었으나, 다른 종류의 곰팡이독소와 다른 경로에 의한 아플라톡신의 섭취를 감안하여, 향후 아플라톡신을 비롯한 포괄적인 곰팡이독소에 관한 연구가 진행되어야 될 것으로 생각된다.
