Pseudotutin previously isolated from Coriaria japonica A. GRAY was revealed to be a molecular compound consisting of equimolar tutin (2) and a new related sesquiterpene lactone, corianin (3). Corianin was also isolated together with coriamyrtin (1), tutin (2) and coriatin (4), from Loranthus parasiticus MERR., a parasitic plant that grows on the twigs of Coriaria sinica MAXIM. The structure of ...

Aflatoxins (AFs) belong to a closely related group of secondary fungal metabolites. These mycotoxins are severely toxic metabolites produced mainly by Aspergillus flavus and A. parasiticus, and exposure to them can cause cancer in humans and livestock [1]. Based on epidemiological evidence, AFs have been classified as human liver carcinogens by the World Health Organization and by the U.S. Envi...

2-Mercaptoethanol inhibits growth of Aspergillus parasiticus NRRL 3240 and aflatoxin formation by the fungus. When added to the resuspended medium, 2-mercaptoethanol inhibited [1-14C]acetate incorporation into both aflatoxins and neutral lipids, thereby showing that it acts at an early stage of aflatoxin biosynthesis. The inhibition is probably due to its chelating action on zinc, which is esse...

Background: In Benin Republic, the conservation of fermented fishes for a long time is difficult due to the contamination of fungi, which lead to its rapid degradation. This experiment was conducted to evaluate the effect of Cymbopogon citratus Essential Oil (EO) against Aspergillus species isolated from fermented fish samples. Methods: Gas chromatography-mass spectrometry was used to determin...

The effects of two Iranian medicinal plants including Zataria multiflora and Geranium pelargoniumwere evaluated on growth-inhibiting of some toxigenic fungi such as Aspergillus flavus, A. parasiticus, A.ochraceus and Fusarium verticillioides. In this study, standard Z. multiflora and G. pelargonium essentialoils (EOs) were diluted in 0.01% dimethyl sulfoxide. Different dilutions of Z. multiflor...

Background and Purpose: Mycotoxins are secondary fungal metabolites with a very high diversity that are produced by some species of Aspergillus which frequently leads to contaminate food and agricultural products. Recently, elimination of aflatoxin contamination in food and feed has been considered by scientists worldwide. Although, the antibacterial and antifungal effects of vitamins as natura...
