This study reports on fungal deterioration of five herbal raw materials and the antifungal, anti-aflatoxigenic, and antioxidant efficacy of Jamrosa essential oil (EO) and its two major components. Herbal raw materials were found associated with 14 fungal species, including strains of aflatoxin-producing Aspergillus flavus. Jamrosa EO and its major components Z-citral and linalyl acetate were assessed against the highest aflatoxin B₁ (AFB₁) producing strain, A.?flavus LHPA₉. Jamrosa EO MIC for A.?flavus LHPA₉ and the concentration that suppressed aflatoxin B₁ production was 0.4?¦Ìl?ml^?1. This EO was found more efficacious than its major components individually as well as in combination. Z-citral inhibited AFB₁ completely at 1.0?¦Ìl?ml^?1 while linalyl acetate did so at 0.7?¦Ìl?ml^?1. The combination of both the compounds completely inhibited AFB₁ production at 0.8?¦Ìl?ml^?1. Free radical scavenging activities (IC₅₀) of EO, Z-citral, linalyl acetate, and a combination of both compounds were 86?¦Ìl?ml^?1, 94?¦Ìl?ml^?1, 217?¦Ìl?ml^?1, and 158?¦Ìl?ml^?1, respectively.
