Abstract
This study included the qualitative chemical tests of some basic ingredients in
Ocimum basilicum leaves. The results showed that the leaves contain glycosides,
alkaloids, tannins, resins, saponins, comarins, flavonoides and phenols. The
inhibition activity of O. basilicum leaves extracts were studied on some pathogenic
microorganisms like Staphylococcus aureus, Salmonella typhi, Escherichia coli,
Vibrio cholerae, Aeromonas hydrophila, Serratia marcescens, Klebsiella pneumonia
and Candida albicans. The results showed that the inhibition activity of the extracts
of O. basilicum leaves varied with different extraction solvents and
microorganisms. The organic phase of petroleum ether showed the best effect of
inhibition activity on the growth of S. marcescens and A. hydrophila which was 21
and 25 mm respectively. While the aqueous phase of chloroform extract had the
best effect on S. aureus and A. hydrophila which reached to 19 and 22 mm
respectively.
