Assessment of toxigenic fungi on Argentinean medicinal herbs.

This work was performed to determine the incidence of toxigenic fungi and their mycotoxins on 152 dried medicinal and aromatic herbs, belonging to 56 species, which are used as raw material for drugs. International methodologies for fungal enumeration and identification were applied as well as TLC and HPLC techniques for toxins detection. The 52% out of 152 samples were contaminated with species from Aspergillus genus, 27% belonging to the Flavi section and 25% to the Circumdati section.
