EFFECT OF SOME MEDICINAL HERBAL EXTRACTS ON CLINICALLY IMPORTANT BACTERIAL PATHOGENSAbstract
Medicinal plant products when compared with synthetic antibiotics minimize the infections at a major part. Phytochemical screening of medicinal plants showed positive results for most of the phytochemical constituents namely tannins, saponins, flavonoids, carbohydrates, alkaloids, anthraquinones, protein and aminoacids, mixed oils and fats etc., This study provided a good medicinal plant based treatment strategy and will create social awareness among the clinically infected patients. Five important bacterial spp., identified from them namely P. aeruginosa, K. pneumoniae, E. coli, S. aureus and B. subtilis. Antibacterial activity of the plant extracts showed different inhibition spectrum against the isolated bacterial pathogens. Among them leaf methanolic extract of Azadirachta indica showed good antibacterial activity.
