GC-MS analysis and antibacterial activity of Amherstia nobilis. W leaf extract

Abstract

Amherstia nobilis W is a plant of Burman origin also known as pride of Burma. It is the only plant found in the genus Amherstia. The present study carried out to analyse the unknown chemical compounds of the plant by GC-MS analysis of ethanolic leaf extract and the antibacterial effect of 70% ethanolic extract. GC-MS analysis revealed the presence of 27 chemical compounds. Some of the major compounds found are PHENOL, 2, 4-BIS (1, 1-Dimethylethyl), Eicosane, Tetradecanoic acid, 3-Heptadecanol, Neophytadiene, Phytol, acetate. Antibacterial activity was carried out using disc diffusion method in Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeroginosa, Escherichia coli. Leaf extractshowed maximum zone of inhibition against Staphylococcus aureus and Pseudomonas aeroginosa.
