In vitro antioxidant activity of C. spinosa extracts and Quercetin as determined by the DPPH and FRAP assays.
| Extract | DPPH (IC 50 value; mg/ml) | FRAP (EC1 value; mg/ml) |
|---|---|---|
| Hydro-alcoholic | 0.034891 ± 0.0017 | 1.655187 ± 0.1219 |
| Ethyl acetate | 0.277039 ± 0.0122a,b | 15.90301 ± 1.082a,b |
| Chloroformic | 0.0392 ± 0.0011 | 3.908373 ± 0.3171a |
| Quercetin | 0.01158 ± 0.00107 | 0.4903 ± 0.05911 |
Values are presented as mean ± S.E.M for 3 replications.
a
Significantly different compared to Quercetin (p < 0.05).
b
Significantly different compared to hydro-alcoholic fraction (p < 0.05).
