An in Vitro Antifungal and Antiaflatoxigenic Properties of Commiphora myrrha and Prunus mahaleb

Aflatoxins and especially aflatoxin B, are the devastating contaminant of food feed products with hazardous effects to mankind his domestic animals. These investigations were set evaluate effect various levels Commiphora myrrha resin (1.0, 1.25, 2.25, 3.25 g/100 ml) Prunus mahaleb seed extract (0.75, 1.5, 2.5, 3.5 on growth secretion by two aflatoxigenic strains Aspergillus flavus A. parasiticus. The plant extracts significantly (p<0.05) decreased secretion, inhibited fungal growth. Resin C. displayed 51.9-95.7% reduction in total flavus, 46.9-92% for parasiticus, Seed P. up 53.7-95.8% 40-94.7%, respectively. inhibition B (B1 B2) myrrh ranged between 51.7-93.5, 50-93.6% (A. flavus) 39.5-89.7%, 37.9-93% parasiticus). mycelial dry weight parasiticus ws 46.1-58.7%, 28.9-51.3% (Myrrh resin), 45-56.9%, 33.3-55.9% (Mahaleb extract). Nonetheless, did not detoxify B1. Therefore, it apparent that affected biosynthesis pathway aflatoxins. Thus, they can be recommended as effective natural biopreservative against contamination products.
