The hydrophilic and lipophilic contribution to total antioxidant activity

Antioxidants extraction from Pinhão ( Araucaria angustifolia (Bertol.) Kuntze) coats and application to zein films

“…The ABTS assay was based on the method of Arnao, Cano, and Acosta (2001), as adapted by Thaipong, Boonprakob, Crosby, Cisneros-Zevallos, and Hawkins Byrne (2006). First, a stock solution was prepared from equal volumes of aqueous solutions of 7.4 mM ABTS and 2.6 mM sodium persulfate.…”

Optimization of microwave-assisted extraction of hydrophilic and lipophilic antioxidants from a surplus tomato crop by response surface methodology

“…To the best of our knowledge only few articles have addressed the H and L intermediate components activity (Arnao et al, 2001;Prieto et al, 2013;Prior et al, 2003).…”

Assessment of effect of hydroalcoholic and decoction methods on extraction of antioxidants from selected Indian medicinal plants

“…There is no single, widely acceptable assay method for evaluating antioxidant capacity applicable to different compounds and different plant extracts, but the most commonly used methods for measuring antioxidant activity are those that involve the generation of free radical species which are then neutralized by antioxidant compounds [24] . However, it is essential to use more than one method to evaluate antioxidant capacity of plant materials because of the complex nature of phytochemicals [25,26] .…”
