Phytochemical Analysis, In Vitro Free Radical Scavenging, and LDL Protective Effects of Different Solvent Fractions of Calotropis procera (R.) Br. Root Bark Extract

Figure 3

(a–f) In vitro antioxidant activity of CPRME and its solvent fractions. All tests were performed in triplicates (n = 3). The statistical significance of antioxidant activity was analyzed for the highest concentration of extract/fractions/standard used in the respective tests. , , , # when compared with HF (the lowest antioxidant activity). ns: not significant. CPRME: Calotropis procera root bark methanol extract; HF: hexane fraction; DMF: dichloromethane fraction; EAF: ethyl acetate fraction; MF: methanol fraction; AF: aqueous fraction; ASA: ascorbic acid; EDTA: ethylenediaminetetraacetic acid.
