Antimicrobial activity of ethanolic extract of the leaf,
stem, seed and fruit of an Indian medicinal plant,
Bryonopsis laciniosa, used traditionally as potent
medication in healing several ailments such as adenopathy,
ague, asthma, bronchitis, cholera, colic, consumption,
convulsion, cough, fertility and phthisis, was tested
against different pathogenic microorganisms by agar well
diffusion method. Leaf and stem extracts of B. Laciniosa
exhibited antimicrobial activity against different Gram
positive and Gram negative bacteria. The extents of the
growth inhibition of bacteria were measured for each extract
and Staphylococcus aureus,
Micrococcus luteus and Bacillus cerues
exhibited significant growth inhibition zone. Minimum
inhibitory concentrations (MIC) exhibited by stem extract
against the tested organisms ranged between 0.156 and 5
mg/ml; and for leaf extracts it varied between 0.625 and 10
mg/ml. Antimicrobial activities of the crude plant extracts
were comparable to those of the standard antibiotics. This
study concluded that B. Laciniosa used as a
traditional medicinal plant has antimicrobial activity
against pathogenic microorganisms.
