Mechanism of antioxidant and antifungal properties of Pimenta dioica(L.) leaf essential oil on Aspergillus flavus.

ABSTRACT: The study explores the antioxidant activity, volatile chemical profile and antifungal potential of Pimenta dioica leaf essential oil (EO) against toxin producing Aspergillus flavus. GC-MS analysis of EO revealed the presence of 41 compounds with eugenol (54%), as the major compound followed by myrcene (16.0%) and chavicol (12.5%). It exhibited the strong antioxidant activity with IC₅₀ value of 19.40 µg/ml and polyphenolic content of 526.9 mg g^-1 gallic acid equivalent. The aflatoxin producing IISRaf1strain from nutmeg (Myristica fragrans) was identified by 18S rRNA sequencing as Aspergillus flavus (MH345939). MIC of P. dioica leaf EO against A. flavus was found to be at 0.04%. The changes in hyphae growth and architecture afte
