Abstract
The study deals with antifungal, antiaflatoxigenic and antioxidant activity of Citrus maxima and Citrus sinensis essential oils (EOs) and their phytochemical composition. The EOs were obtained by hydrodistillation and their chemical profile was determined through GC and GC–MS analysis. Both the EOs and their 1:1 combination showed broad fungitoxic spectrum against different food contaminating moulds. The EOs and their combination completely inhibited aflatoxin B1 (AFB1) production at 500ppm, whereas, dl-limonene, the major component of EOs showed better antiaflatoxigenic efficacy even at 250ppm. Both the oils exhibited antioxidant activity as DPPH free radical scavenger in dose dependent manner. The IC50 for radical scavenging efficacy of C. maxima and C. sinensis oils were to be 8.84 and 9.45μlml−1, respectively. The EOs were found non-mammalian toxic showing high LD50 for mice (oral, acute). The oils may be recommended as safe plant based antimicrobials as well as antioxidants for enhancement of shelf life of food commodities by checking their fungal infestation, aflatoxin production as well as lipid peroxidation.
