The methanolic extract of Commelina communis (aerial part) showed antibacterial activity against a cariogenic bacterium, Streptococcus mutans OMZ 176. The active principles were identified to be $\beta$-carboline alkaloids, 1-carbomethoxy-$\beta$-carboline, norharman and harman, which were bactericidal in the minimal inhibitory concentration (MIC) of $100\;\mu{g/ml}$ against the strain.

The alkaloidal constituents of Commelina communis(Commelinaceae) were investigated. From the ether soluble alkaloidal fraction, three ${\beta}-carboline$ type alkaloids were isolated by chromatographic purification process. Their chemical structures were identified as $1-carbomethoxy-{\beta}-carboline$, norharman and harman from the physicochemical data, which were newly isolated from this plant.
