Abstract :
Ocimum basilicum leaves is a plant that contains essential oils and
phenolic compounds that have the potential to be developed as antibacterial. The
most important content in basil is the essential oil found in the leaves and the parts
that grow above the ground. This study aims to determine the antibacterial activity
of the ethyl acetate fraction of basil leaves against Pseudomonas aeruginosa and
Staphylococcus aureus.
Ocimum basilicum leaves fraction is the result of fractionation of ethanol
extract of basil leaves obtained by suspension using water and then fractionated
using liquid-search fractionation (FCC) method. The ethyl acetate fraction
obtained was then tested for antibacterial activity with concentrations of 25%,
50% and 100% using the disc diffusion method. In this study, a positive control of
5µl ciprofloxacin and a negative control of 10% DMSO was used.
The results showed that the ethyl acetate fraction could inhibit the
growth of Pseudomonas aeruginosa and Staphylococcus aureus bacteria, but it
was significantly different from the positive control of ciprofloxacin. The ethyl
acetate fraction of Ocimum basilicum leaves which gave the greatest inhibition
zone against Pseudomonas aeruginosa was at a concentration of 100% with an
average inhibition zone diameter of 18.9 mm and the greatest inhibition zone
against Staphylococcus aureus was at a concentration of 100% with an average
diameter of the inhibition zone of 14.13 mm.
