A simple metal nanoparticles (MNPs) based colorimetric assay for the antioxidant capacity of Saffron polyphenolics is proposed. The proposed method has been compared with the commonly used classical assays (FC and ABTS); a significant similar response trend was found with the ABTS. Additionally, it was also found that the proposed approach was polyphenols selective versus other endogenous antioxidants as safranal and crocin.

Abstract
A simple metal nanoparticles (MNPs) based colorimetric assay for the antioxidant capacity of Saffron polyphenolics is proposed. The proposed method has been compared with the commonly used classical assays (FC and ABTS); a significant similar response trend was found with the ABTS. Additionally, it was also found that the proposed approach was polyphenols selective versus other endogenous antioxidants as safranal and crocin.File in questo prodotto:
