ABSTRACT
Ocimum basilicum L., commonly sweet basil, belongs to the Lamiaceae family and is characterized by an essential oil primarily composed of monoterpenes, sesquiterpenes, and phenylpropanoids. Viral infections can influence the levels of these compounds. The cucumber mosaic virus (CMV), which causes viral diseases in numerous significant crops globally, has been identified in the basil plant (Ocimum basilicum). Samples from infected basil plants, particularly the green shoot leaves, exhibited necrotic local lesions, smaller leaf size than usual, and yellow mottling accompanied by crinkling. The primary objective of this study was to examine the impact of CMV infection on the essential oil profile of common basil. Plants with two pairs of leaves above the cotyledons were inoculated with an unidentified virus obtained from a field plant displaying chlorotic yellow spots and foliar deformation. Essential oils from both healthy and infected plants were extracted through hydro distillation and subsequently analyzed using GC-MS. Notable alterations in the essential oil composition due to viral infection were recorded. The principal constituents identified were methyleugenol and p-cresol, 2,6-di-tert-butyl; however, the levels of methyleugenol were significantly reduced in the infected specimens.
