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

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 200 ml of 95% ethanol solution. Extract was treated against four bacterial strains (Proteus vulgaris, Pseudomonas aeruginosa, Staphylococcus aureus and Lactobacillus sp.). Flower extract shows inhibition zone diameter of 8.00±1.00 mm lower to that of leave extract with the inhibition zone diameter of 10.00±1.08 mm against the growth of Pseudomonas aeruginosa. Flower extract also shows inhibition zone diameter of 7.75±0.75 mm which is significantly lower to that of leave extract with inhibition zone diameter of 17.75±0.85 mm against the growth of Staphylococcus aureus. The study however, indicated that ethanol extracted leave of wide sage is significantly active against staphylococcus aureus and and moderately active on Pseudomonas aeruginosa which are causal agents of urogenital, skin and health related infections.
