Reinvestigation of Essential Oil of Rabdosia melissoides: Chemical Composition, Antioxidant, Anti-inflammatory, Analgesic, Antipyretic, Antifungal and Antibacterial Activities

Abstract

The essential oil of Rabdosia melissoides (Lamiaceae) was analyzed by GC and GC-MS and compared to earlier studies. The analysis led to identification of 56 components representing 100.00% of the total oil represented by carvacrol (31.1%), p-cymene (14.2%), menthol (10.4%), β-bisabolene (8.7%), 4-vinylguaiacol (8.2%), thymol menyl ether (5.2%), thymol acetate (3%), γ-terpinene (2.9%), α-humulene (1.9%), menthone (1.4%) and pluegone (1.1%) as major constituents. The essential oil was examined for its possible antioxidant, anti-inflammatory, analgesic antipyretic, antifungal and antibacterial activities.
