Aim of the studyThe leaves and root of Toddalia asiatica (L.) Lam. (Rutaceae) are widely used as a folk medicine in India. Hexane, chloroform, ethyl acetate, methanol and water extracts of Toddalia asiatica leaves and isolated compound Flindersine were tested against bacteria and fungi.Materials and methodsAntibacterial and antifungal activities were tested against bacteria and fungi using disc-diffusion method and minimum inhibitory concentrations (MICs). The compound was confirmed using X-ray crystallography technique.ResultsAntibacterial and antifungal activities were observed in ethyl acetate extract. One active principle Flindersine (2,6-dihydro-2,2-dimethyl-5H-pyrano [3,2-c] quinoline-5-one-9cl) was isolated from the ethyl acetate extract. The MIC values of the compound against bacteria Bacillus subtilis (31.25 μg/ml), Staphylococcus aureus (62.5 μg/ml), Staphylococcus epidermidis (62.5 μg/ml), Enterococcus faecalis (31.25 μg/ml), Pseudomonas aeruginosa (250 μg/ml), Acinetobacter baumannii (125 μg/ml) and fungi Trichophyton rubrum 57 (62.5 μg/ml), Trichophyton mentagrophytes (62.5 μg/ml), Trichophyton simii (62.5 μg/ml), Epidermophyton floccosum (62.5 μg/ml), Magnaporthe grisea (250 μg/ml) and Candida albicans (250 μg/ml) were determined.ConclusionsEthyl acetate extract showed promising antibacterial and antifungal activity and isolated compound Flindersine showed moderate activity against bacteria and fungi.
