Isolation and identification of toxigenic and non-toxigenic fungi in samples of medicinal plants from the market
ABSTRACT:The consumption of preparations of medicinal plants has been increasing during the last decades in occidental societies. The presence of toxigenic fungi in a plant product may represent a potential risk of contamination, because of aflatoxins and ochratoxins. In this study, 12 samples of me...

| description | ABSTRACT:The consumption of preparations of medicinal plants has been increasing during the last decades in occidental societies. The presence of toxigenic fungi in a plant product may represent a potential risk of contamination, because of aflatoxins and ochratoxins. In this study, 12 samples of medicinal plants were analyzed in relation to the level of fungal contamination, and the presence of producers of ochratoxin A and aflatoxins was assessed by visualization of fungi using a cromatovisor in coconut milk. Most of the species found belong to the genus Cladosporium, Fusarium, Aspergillus and Penicillium. Species producing ochratoxin A were present in 2 samples (16.7%), Melissa and Hibiscus. Species producing aflatoxin were found in samples of Jacaranda decurrens (8.33%). This study suggests that herbs, if stored improperly, can provide the growth of fungi and should be examined before consumption. |
