Abstract

Genus Becium of Lamiaceae family encounters numerous medicinally and economically valued aromatic plants. The hydrodistilled essential oil of Becium grandiflorum (Lam.) Pic.Serm. aerial part was analyzed using GC/MS. A total of 32 compounds amounting to 99.68% of the essential oil were identified. Oxygenated diterpenes constituted the largest share (43.45%) in the studied oil followed by sesquiterpenes hydrocarbons (34.24%). Pimara-7,15-dien-3-ol (20.58%), 3-α-hydroxymanool (14.07%), caryophyllene (8.17%), sandaracopimaradiene (7.98%), selina-3,7(11)-diene (5.61%), and germacrene D (4.95%) are the chief identified compounds in B. grandiflorum essential oil. The essential oil was assessed for its antiviral potential against herpes simplex virus 1 (HSV-1) at a non-cytotoxic concentration using cytopathic effect (CPE) inhibition assay on the Vero cell line. B. grandiflorum essential oil exhibited a pronounced in vitro cytotoxicity against Vero cells with 50 % cytotoxic concentration (CC50) of 7.75 ± 0.84 µg/mL and weak anti-HSV-1 potency with percent inhibition of 21.36 ± 2.13 at a maximum non-toxic concentration of 1 µg/mL.
