Phytochemical Screening and Antibacterial Activity of Aqueous and Methanolic Leaf Extracts of Two Medicinal Plants against Bovine Mastitis Bacterial Pathogens

Spathodea campanulata P. Beauv is extensively used in Indian traditional and folklore medicines to cure various human ailments. Tridax procumbens Linn is a tropically distributed medicinal plant. Antimicrobial activity of aqueous and methanol extracts of two plants were investigated by agar disc and well-diffusion method against bovine mastitis bacterial pathogens. The plant extracts showed inhibitory activity against the tested organisms. Phytochemical screening of the plant revealed the presence of tannins, flavonoids, saponins and alkaloids. The study scientifically validates the use of plant in traditional and ethnoveterinary medicine.
