Extraction and antibacterial activity of nahar (Mesua ferrea) seed kernels’ oil

There is a growing need to explore more sustainable and alternative sources of oil as a result of the increasing demands for oils both for human consumption and other industrial applications. The aims of this work were thus; to determine the effect extraction temperature, time and solvent type on oi...
