Our paper shows the results of 302 samples of herb medicines about fungal contamination at Yakyeang markets in Seoul. The sample medicines were treated VICAM pretreatment and analysed by post column derivatisation procedure( PHRED-HPLC) with a fluorescence detector. Aflatoxin B1 was founded from 50.3% of samples, aflatoxin B2 was 39.7%, aflatoxin G1 was 21.2% and aflatoxin G2 was 23.5%. The detected ranges of aflatoxin B1, B2, G1 and G2 were from 0.1 to 57.2 ㎍/㎏, 0.1 to 42.6 ㎍/㎏, 0.1 to 23.5 ㎍/㎏ and 0.1 to 9.5 ㎍/㎏ respectively. Among total samples, 26 samples contained aflatoxin B1 violated the regulation (less than 10 ug/㎏) for aflatoxin B1 of KFDA. From the result, we could presumed that more than a half of samples were contaminated by aflatoxins. Therefore, it seems to be necessary that the new safety giudeline will be established aflatoxin B2, G1 and G2 from herb medicines as aflatoxin B1.
