Abstract:
The study investigated the effects of extracts of chloroform, methanol and ethanol of Allium sativum on the growth of species of
Aspergillus fumigatus, Penicillium and Rhizopus stolonifer isolated from guinea corn
. Between the minimum inhibitory concentration ranges of 20 mg / mL to 40 mg / mL the fungi were susceptible. The chloroform extract showed more inhibitory effect compared to ethanol and methanol extracts. An assay of the antifungal properties of these extracts indicated that the most resistant of all the test fungi appeared to be
Aspergillus fumigatus while the most susceptible species were Penicillium. The investigation on the antifungal effect of
Allium sativum on the growth of fungi isolated from Guinea corn demonstrated that
Allium sativum has proven to be an effective antifungal agent against species
of Aspergillus fumigatus Rhizopus stolonifer, and
Penicillium. The results therefore suggests that extracts of
Allium sativum may be an important preservative for Guinea corn. Phytochemical screening of extracts of
Allium sativum also showed that the extracts contained saponins, tannins flavonoids, and anthraquinones.
