Abstract

The aim of this study was to assess and compare the antioxidant potential and total phenolic content of ethanolic and aqueous extracts of the fruits of Prosopis cineraria and Capparis decidua. Free radical scavenging activity of the extracts in the concentration range 0.5–40.0 mg/cm3 was determined by DPPH (2.2-diphenyl-1-picrylhydrazyl) assay using BHT as a standard. IC50 values for the ethanolic and aq. extracts of P. cineraria (7.026 ± 0.088 mg/cm3 and 4.097 ± 0.033 mg/cm3) were found to be significantly (p ≤ 0.05) lower than the corresponding extracts of C. decidua (47.538 ± 0.040 mg/cm3 and 14.066 ± 0.039 mg/cm3). Total phenolic content for the aq. extract of P. cineraria (3.512 ± 0.013 mg GAE/g) was significantly (p ≤ 0.05) higher than aq. extract of C.decidua (2.142 ± 0.032 mg GAE/g), whereas the ethanolic extracts of the two plants did not show any significant difference in their phenolic content. The FRAP value for the aq. extract of P. cineraria (17.951 ± 0.026 mg Fe(II) eqv/g) and C. decidua (21.343 ± 0.009 mg Fe(II) eqv/g) was significantly (p ≤ 0.05) higher than their corresponding ethanolic extracts (2.742 ± 0.023 and 2.313 ± 0.020 mg Fe (II) eqv/g). The reducing capacity by ferrozine assay for the ethanolic and aq. extracts of P. cineraria (4.767 ± 0.4877 and 10.370 ± 0.005 mg AE/g) were significantly (p ≤ 0.05) higher as compared to the ethanolic and aqueous extracts of C. decidua (0.160 ± 0.136 and 1.537 ± 0.046 mg AE/g).
