Present study assayed the toxicity effect of ethanolic leaf and seed extract of Cassia alata and found promising activity. From the probit transformation of resulting mortality data we got LC₅₀values of 4.31 ppm (μg mL^-1) for seed and 5.29 ppm for leaf extract. Seed extract explored potent cytotoxicity similar to the standard gallic acid (LC₅₀ = 4.53 ppm). From the antibacterial and MIC data it was evident that seed extract gave least activity against the tested bacteria whereas leaf extract deserved promising antibacterial activity.
