Various organic and aqueous extracts of aerial part of Boenninghausenia albiflora(Rutaceae) obtained by infusion and maceration were screened for their antimicrobial activity against eight animal and plant pathogenic bacteria (Bacillus subtilis, Staphylococcus aureus, Erwinia chrysanthemi, Escherichia coli, Proteus vulgaris, Xanthomonas phaseoli, Agrobacterium tumefaciens and Xanthomonas campestris) using disc diffusion method. Out of total 32 tests performed, 27 tests showed positive antibacterial activity at 1000 mg/ml concentration, whereas 15 instances exhibited zone of inhibition ³ 10 mm at same concentration. The activity shown by some of the extracts was found higher than ampicillin (10 mcg) and erythromycin (15 mcg), standard antibiotic used.
Key words: Boenninghausenia albiflora, Rutaceae, antibacterial, ampicillin, erythromycin.
