Biflavonoids from Brazilian pine Araucaria angustifolia as potentials protective agents against DNA damage and lipoperoxidation

Biflavonoids from Araucaria angustifolia were able to protect against DNA damage and lipoperoxidation promoved by reactive species (RNOS). The 1O 2 quenching rate constant using the time-resolved near infrared luminescence technique was also determined. A biflavonoid fraction (BFF) obtained from Ara...
