Abstract
Cordia dichotoma Forst.f. bark, identified as botanical source of Shlesmataka in Ayurvedic pharmacopoeias. Present study was carried out with an objective to investigate the antibacterial and antifungal potentials of Cordia dichotoma bark. Antibacterial activity of methanol and butanol extracts of the bark was carried out against two gram negative bacteria (Escherichia coli, and Pseudomonas aeruginosa) and two Gram positive bacteria (St. pyogenes and Staphylococcus aureus). The antifungal activity of the extracts was carried out against three common pathogenic fungi (Aspergillus niger, A.clavatus, and Candida albicans). Zone of inhibition of extracts was compared with that of different standards like Amplicilline, Ciprofloxacin, Norfloxacin and Chloramphenicol for antibacterial activity and Nystain and Greseofulvin for antifungal activity. The extracts showed remarkable inhibition of zone of bacterial growth and fungal growth and the results obtained were comparable with that of standards drugs against the organisms tested. The activity of extracts increased linearly with increase in concentration of extract (mg/ml). The results showed the antibacterial and antifungal activity against the organisms tested.
