FRAP measured the ability of antioxidants to reduce the ferrictripyridyltriazine
(Fe3+-TPTZ) complex to the blue-colour complex
of ferrous-tripyridyltriazine (Fe2+-TPTZ) in acidic conditionsP. emblica L. had the highest FRAP value
(652 ± 260 lmolTE/g), followed by S. pinnata (L.f.) Kurz (424 ±
39 lmolTE/g) and A. velutinosum Blume (118 ± 81 lmolTE/g)
