Effects of drying on total polyphenols content and antioxidant properties of <scp><i>Carica papaya</i></scp> leaves

Hot air and shade drying are not conducive with repect to preserving the antioxidants as a result of possible thermal degradation at elevated temperatures and oxidations under prolonged drying condition. © 2020 Society of Chemical Industry.
