Abstract

The aim of this study is to evaluate the inhibition of Aspergillus flavus and Aspergillus parasiticus isolated from peanut and their aflatoxin production exposed to the essential oils extracted from fresh leaves of Ocimum canum. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oil were determined. The essential oil was found to be strongly fungicidal and inhibitory to aflatoxin production. Through GC/MS analysis, an amount of 30 components were identified, representing almost 95.2% of the oil. Essential oil of O. canum was characterized by major components such as terpinene-4-ol (41.18%), linalol (14.7%) and -terpinène (6.9%). This plant offers novel approach to the management of storage fungi
