Phytochemical screening, bioautography and antibacterial evaluation of the methanolic extract of Glycine Max (Soybean)

Abstract

Glycine max belongs to the family Fabaceae. It is called Soybean.

Phytochemical analysis of Glycine max has revealed that numerous compounds

in plants traditionally used for medicinal purposes have many therapeutical

properties. The result of the phytochemical studies revealed the presence of

Saponins, Tannins, Alkaloids, Steroids and numerous other chemicals.

Saponins, Tannins and alkaloids are chemicals that are known to have anti

bacterial properties. The concentrations of the plant used were 25 mg/ml, 50

mg/ml and 100mg/ml respectively. At these concentrations, the extract

inhibited the growth of Escherichia Coli, Pseudomonas Aeruginosa and V.

Harveyi and produced percentage inhibition ranging between 67.6% to 82.8%.

The anti-bacterial activity demostrated by the plant extract may due to the

presence of the phytochemicals present in the plant.
