Antibacterial and Antifungal Activities of the Medicinal Plant Veronica biloba

Plants are naturally God gifted for the synthesis of medicinal
compound and provide a great help in a new discovery in the
area of chemical diversity because of the unknown availability
either as a standardized extract or as a pure compound.
The medicinal plant Veronica biloba extracts obtained through
Soxhlet and maceration methods were subjected to preliminary
antimicrobial screening against pathogenic microorganisms.
Fractionation was performed using liquid- liquid extracts such
as ethyl acetate, water, dichloromethane, and hexane extract of
plant, and the fractions were tested for antifungal
activity and antibacterial activity using well- diffusion method
at sample concentration of 10–30 μL. The result indicated
that all extracts exhibited antimicrobial activity against all
test pathogens. The ethyl acetate extract showed greater activity
than other corresponding extracts. Among various extracts,
only the ethyl acetate extract show potential against bacterial
(gram negative and gram positive) and fungus test strain greater
than standard Nystatin test control. Thus, the extract of Veronica
biloba could be used to treat microbial (fungus and bacterial
strain) infection.
