Table 2.
Total phenol content and antioxidant power of the formulations. FRAP and CUPRAC values are expressed as Fe2+ mmol/l, DPPH• and ABTS•+ values are expressed as Trolox equivalent antioxidant capacity (TEAC, mmol/L), total phenol content measured by Folin-Ciocalteu’s assay is expressed as gallic acid equivalent (GAE). Mean values ± standard deviations have been reported. Means in each column not sharing a superscript letter are significantly different (p ≤ 0.05).
