Effects of Cultivar on Phenolic Content and Antioxidant Activity of Naked Oat in China
To evaluate the effects of naked oat cultivars on their phenolic contents and antioxidant activities, the oat seeds from 21 different cultivars in China were collected, and their major nutritional components, compositions of polyphenols, and antioxidant activities were measured. As the results, oat...
