Abstract:
Now a day utilization of plants’ extract as alternative medicine becomes a common practice all over the world
merit many scientists to examine the antimicrobial activity of several medicinal plants. Maesa lanceolata is one
of such ethnomedicinal plant traditionally utilized as a cure for the treatment of pain against various diseases.
Besides, there is plenty of research done on the determination of which potential constituents of this plant are
responsible for such treatment. In this study, an attempt has been made to extract oil from Maesa lanceolata seed
using n-hexane solvent, evaluate its physio-chemical properties, and antimicrobial activity on a selected strain of
bacterial and fungal. The maximum oil yield of 35.3% was obtained at the optimum parametric values;
extraction temperature of 70 ◦C, extraction time of 6 h, solute to solvent ratio of 0.06 g/ml, and particle size of
0.25 mm. The chemical compositions and functional group of the extracted oils were determined using Gas
Chromatography mass spectroscopy and Fourier Transform Infrared Spectroscopy analysis. The result shows that
the abundant fatty acid was monounsaturated oleic acid C18:1 (53.49%) and poly-unsaturated linoleic acid
C18:2 (31.48%). The qualitative analysis test of the extracted m. lanceolata seed oil shows the presence of
different phytochemical constituents which are microbial resistant and having an antimicrobial activity like
flavonoids, alkaloids, tannins, saponin, Terpenoids, and phenols.
