Abstract:
Physalis minima is an important medicinal plant of Indian System of Medicine. This plant is reported for its diuretic, laxative and antiinflammatory activities. However, the plant is not well scrutinized for its antimicrobial potential. The major chemical constituents reported from the plant are phenolics and alkaloids, which suggest that the plant may turn out to be a potent antiinfective agent. The aim of the study was to find out the antibacterial potential of mature berries of P. minima using streak plate, well diffusion, determination of minimum inhibitory concentration and bioautographic methods against a battery of Gram positive and Gram negative bacterial strains. Results of the study showed that methanol and chloroform extracts of P. minima exhibited potent inhibitory activity against all the bacterial strains tested. Minimum inhibitory concentration found out was 100 μg in both the extracts. Bioautography assay showed polar compounds present in the crude extract are responsible for the antimicrobial action.
