Wild Sage(Lantana camara)Flower and Leave: Bactericidal Efficacy on Bacterial Growth

AUTHORS: Umoren, O. D.

ABSTRACT:Plants contains myriad amount of chemical with medicinal properties. This study aim at evaluating the antibacterial efficacy of wide sage leave and flower extracted with ethanol on some bacterial growth. Flower and leave of Wide sage collected from the vicinity of Abeokuta were washed, sun-dried, grinded and extracted with 200mlof 95% ethanol solution. Extract was treated against four bacterial strains (Proteus vulgaris, Pseudomonas aeruginosa, Staphylococcus aureusand Lactobacillus sp.). Flower extract shows inhibition zone diameter of 8.00±1.00 mm lower to that of leave extract with theinhibition zone diameter of 10.00±1.08mm against the growth ofPseudomonas aeruginosa.Flower extract also shows inhibition zone diameter of 7.75±0.75 mm which is significantly lower to that of leave extract withinhibition zone diameter of 17.75±0.85mm against the growth ofStaphylococcus aureus. The study however, indicated that ethanolextracted leave of wide sage is significantly active against staphylococcus aureus andand moderately active onPseudomonas aeruginosa which are causal agents of urogenital, skin and health related infections.
