Abstract

ABSTRACTThe antifungal and antifumonisin activities of Artabotrys odoratissimus essential oil (AOEO) were evaluated. The GC-MS analysis of AOEO confirmed the presence of 14 phytoconstituents, among which, 3-carene (44.91%), β-caryophyllene (19.17%), α-humulene (8.78%), α-copaene (6.59%) and caryophyllene oxide (5.55%) were recorded as major phytoconstituents. The AOEO showed promising antifungal activity against 15 field and storage fungi with percent mycelial growth inhibition, minimum inhibitory concentrations (MICs) and minimum fungicidal concentrations (MFCs) ranging between 11.45 and 42.53% at 1 µL mL–1, 0.078 and 1.25 µL mL–1 and 2.5 to >10.0 µL mL–1, respectively. The fumonisin B1 (FB1) and ergosterol productions were completely inhibited by AOEO at 8 µL mL–1. The results revealed that AOEO could be explored for management of mold and mycotoxin contaminations in food and animal feed.
