Monitoring of anti-aflatoxgenic activity of medicinal plants againstAspergillus flavusto protect stored layer hens feed

摘要

Medicinal plantsFicus religiosa, Citrus paradisi, Vitis vinifera, Ficus benghalensis, Gardenia radicans, Ziziphus Jujuba, Morus alba, Punica granatum, andPsidium guajavawere evaluated for their anti-aflatoxigenic activities. The layer hens feed contaminated withA. flavuswas treated with plant leaves at different concentrations and feed was stored at 28 degrees C and 16% moisture level for 6 months and subjected to aflatoxins B1 and B2 (AFB1, AFB2) monitoring.P. granatumandM. albashowed 100% inhibition. Both types of AFs were not detected up to 180 days.Z. Jujuba, V. viniferaandF. benghalensiscontrolled AFB2 completely; however, at the end of 180 days, a small amount of AFB1 was observed.P. guajava, C. paradise, G. radicansandF. religiosaalso controlled AFB1 and AFB2, but at higher concentration. In comparison to the European Commission and FAO standards for AFB1, at the end of the storage period, the AFs detected were within permissible limits. In view of considerable antifungal activities, the AFs produced byA. flavuscan be controlled byP. granatum and M. albaplants to protect feed from fungal attack and AFs production during storage.
