The current study evaluated the antioxidant, antibacterial, and enzyme inhibitory activity of extracts obtained from the seeds of C. absus L. (Leguminosae) to determine a mechanism for the traditional use of the seeds. Crude ethanolic extract of C.absus seeds was prepared by maceration method and n-butanol, choloroform, n-hexane and water fractions were prepared from crude ethanol extract. The antibacterial activity of samples was determined by agar well diffusion and broth micro dilution assay. The antioxidant activity of the crude extract and fractions was evaluated for free radical scavenging activity by DPPH assay. The enzyme inhibition activity of crude extract and fractions was determined against urease, carbonic anhydrase and xanthine oxidase. The n-hexane and n-butanol fractions showed promising activity against gram-positive bacteria when compared with ceftriaxone as a standard. Moreover, the crude ethanol extract and water fraction displayed the most potent activity in urease inhibition assay. The results showed that crude extract and all the fractions have urease inhibition. In the case of carbonic anhydrase, only the crude eth...
