Inhibitory effect of various aqueous medicinal plant extracts on citrinin production and fungal biomass by Penicillium notatum

Citrinin is a nephrotoxic mycotoxin produced by several species of the genus and Monascus. Citrinin is generally formed after harvest and occurs mainly in stored grains. efficacy of different concentrations of aqueous leaf extracts of Rhazya stricta Decne and Cleome amblyocarpa two fungal strains Penicillium notatum and Aspergillus niger and fungal biomass by the isolates was suppressed, depending on the concentration of the plant extract added to culture media at the time of spore i grown for 15 days in culture media containing 5 oleander, R. stricta Decne and C. amblyocarpa Penicillium notatum and 13.4 to 90.3% in stricta Decne was more efficient than other tested plant extracts in inhibiting the citrinin production ranging from 22.4 to 91.8% in P. notatum
