Fungi associated with Glycyrrhiza uralensis and their capability of mycotoxin production
甘草药材上的污染真菌类群及其产毒素特性

Mouldiness of medicinal herbs occurred commonly during storage. Fungi associated with mouldy materials of Glycyrrhiza uralensis and their capability of mycotoxin production were investigated. Medicinal materials of G. uralensis were collected from herbal markets. Seven fungal species belonging to Penicillium, Aspergillus, Fusarium and Mucor were isolated. Among them, Penicillium polonicum, Aspergillus parasiticus and P. crustosum were dominant. Mycotoxin production was detected by HPLC-MS technique. Aspergillus parasiticus produced aflatoxins (AFG2, AFG1, AFB2, AFB1) and ochrotoxin A (OTA), while Penicillium polonicum mainly produced ochrotoxin A (OTA).
