Aqueous extracts of plant parts of C. sappan showed significant
antimicrobial activity, which was similarly reported earlier in bark
extracts only[23]. Furthermore, petroleum ether extract from leaves
of C. sappan had been reported to have the minimum antimicrobial
activity against tested pathogenic bacteria used for assay. However,
there were no any antimicrobial assay reports on seed extracts of
C. sappan, and in case of leaves, bark and heart wood few reported
in aqueous extracts has been observed[23-26], but none in organic
solvents such as petroleum ether, methanol and chloroform.
