Abstract: This present study deals with the quantitative and qualitative phytochemical
screening, the antimicrobial properties and thin layer chromatography of Lavandula
angustifolia leaves extracts. These were achieved using the cold maceration method of
extraction involving hexane, water (aqueous) and ethanol, to ensure that a wide polarity
range of components are extracted. Alkaloid, phenol, flavonoids, tannins, terpenes,
glycosides and steroids were observed present in the leaves extract of this plant. Quantitative
analysis was also conducted to determine the percentage composition of some of the
secondary metabolites, and the antimicrobial sensitivity test was carried out using the well
diffusion method to determine the susceptibility of the plant. It was interesting to note that
the hexane extract of L. angustifolia have great potential of been used as a phytomedicine
especially against the deadly salmonella typhi associated diseases e.g fever, malaria and
typhoid at a better extent than the commercially available erythromycin drug which was used
as control. This plant extracts were also discovered to be very active against pathogenic
bacteria like Escherichia coli and Pseudomonas aeruginosa at great and encouraging
degrees.
