Abstract
Skimmia anquetilia is a plant species native to the Western Himalaya region that has tremendous potential for phytochemical activities. This study aimed to identify bioactive compounds and assess the antibacterial activity of S. anquetilia. To determine the major bioactive chemicals in the methanol leaf extract of S. anquetilia, we used a gas chromatography-mass spectrometer (GC-MS). The presence of 35 distinct phytoconstituents was discovered using GC-MS, which could contribute to the therapeutic capabilities of this plant species. The most predominant compound was 2R-acetoxymethyl-1,3,3-trimethyl-4t-(3-methyl-2-buten-1-yl)-1t-cyclohexanol (23.9%). Further, the leaf extract was evaluated for antibacterial activity against Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, and Staphylococcus aureus. The extract showed the highest zone of inhibition against E. coli (19 mm) followed by P. aeruginosa (18 mm) and K. Pneumoniae (17 mm) at 160 mg mL-1. The minimum inhibitory concentration (MIC) of methanol extract against the strain of P. aeruginosa (2 mg mL-1) demonstrated significant antibacterial activity. The findings of the present study highlight the potential of S. anquetilia for the development of herbal medicines for the treatment of various pathogenic infections.
