Objective: To evaluate and compare the maximum antimicrobial activity by screening different
parts of Caesalpinia sappan L. extracted in different solvents against Salmonella ebony (MTCC
3384) (S. ebony), Klebsiella pneumoniae (MTCC 432) (K. pneumoniae), Escherichia coli (MTCC
443) (E. coli) and Bacillus subtilis (MTCC 10619) (B. subtilis).
Methods: Dried plant parts were extracted with petroleum ether, methanol, chloroform and
water by Soxhlet extraction method. The extracts were tested against S. ebony, K. pneumoniae, E.
coli and B. subtilis by using the agar well diffusion method.
Results: Among the above solvents, the methanol and chloro...
