It was 168 ± 2 mg GAE/g dw for SPP, and 101 ± 1 mg GAE/g for SPT ( Table 1). pinnata extracts show high levels of polyphenols in both S. The total phenolic content (TPC) determined for S. pinnata leaves are active even on ABTS radical cation and show good antioxidant capacity. The TEAC values were 0.61 ± 0.01 and 0.310 ± 0.004 μmol Trolox/g for the two extracts of SPP and SPT, respectively ( Table 1). + radical assays were presented as Trolox equivalent antioxidant capacity (TEAC) using Trolox as reference standard.pinnata leaves of both sites have good antioxidant capacity even if lower than pure ascorbic acid (IC50 = 2.5 ± 0.2 ARA = 0.40 ± 0.02). These results of scavenging activities indicate that S. To show values directly dependent on antioxidant activity, antiradical activity (ARA) was calculated as 1/IC50. The DPPH radical have a low value of IC50 ( Table 1). + and DPPH in a concentration-dependent manner.pinnata extracts were capable of scavenging ABTS
