Among the above solvents, the methanol and chloroform and aqueous extracts
of leaves, seeds, bark and heart wood showed strong antibacterial activity. The inhibition
zone for heart wood extracts against K. pneumoniae was (30.333 ± 0.330) mm in methanol,
chloroform (28.166 ± 0.730) mm and aqueous extract (28.166 ± 0.170) mm; for B. subtilis,
that was (27.333 ± 0.440) mm in methanol, (27.166 ± 0.170) mm in chloroform, (26.166 ±
0.440) mm in aqueous extract and least in petroleum ether (12.660 ± 0.170) mm. The leaf
extracts in methanol showed maximum antibacterial activity against S. ebony as seen by the
inhibition zone (16.000 ± 0.290) mm and K. pneumoniae (13.000 ± 0.290) mm. The maximum
antibacterial response of the seed extract against K. pneumoniae was observed in chloroform
solvent (14.000 ± 0.580) mm followed by aqueous extract (13.833 ± 0.600) mm. No response
was observed in petroleum ether and methanol.
