Determination of antioxidant property and their lipophilic and hydrophilic phenolic contents in cereal grains

Improvement in nutritional attributes of rice using superheated steam processing

“…2C) tests was used in this study to provide a more reliable assessment of the antioxidant activity of rice samples. In this study, ABTS and FRAP values are concordant, although not necessarily identical, which is in agreement with the observation of Deng et al (2012). There is no absolute one to one relationship between antioxidant activity and phenolic content, but overall ABTS and FRAP values rise and fall in parallel with the corresponding phenolic content.…”

Total phenolic contents and antioxidant capacities of 51 edible and wild flowers

“…Therefore, natural antioxidants have become important to protect food and also enhance the body's antioxidant defense system. Vegetables, fruits, cereals, medicinal plants and microalgae were widely evaluated to find natural antioxidants (Chandrasekara & Shahidi, 2010, 2011a, 2011bDeng et al, 2012;Eberhardt, Lee, & Liu, 2000;Fu et al, 2011;Li, Wang, Li, Li, & Wang, 2009b;Li, Wong, Cheng, & Chen, 2008;Li et al, 2007Li et al, , 2009aStangeland, Remberg, & Lye, 2009). In addition, some flowers have been eaten since the 16th century in European.…”

Antioxidant capacities and total phenolic contents of 56 vegetables

“…Natural antioxidants present in fruits and vegetables, such as vitamins and phenolic compounds, are considered to be responsible for these chemopreventive effects (Ruxton, Gardner, & Walker, 2006;Saura-Calixto & Goñ i, 2006). Due to these attractive advantages of natural antioxidants, increasing attention has been paid to screen out preferably natural sources of antioxidants (Chandrasekara & Shahidi, 2010, 2011aDeng et al, 2012;Li, Wong, Cheng, and Chen, 2008;Li et al, 2007;Stangeland, Remberg, & Lye, 2009). Especially, phenolic compounds are one of the most important natural antioxidants because of their important bioactivities (Chandrasekara, & Shahidi, 2011b;Fresco, Borges, Diniz, & Marques, 2006;Scalbert, Johnson, & Saltmarsh, 2005).…”
