Antioxidant and skin protection effect of morin upon UVA exposure > REFERENCE LIBRARY

Abstract

Background

Morin is a family of phenolic compounds and is a bioflavonoid ingredient in fruits and vegetables. Morin exhibits various biological activities, including antioxidant cell protection and antimutagenic and anti-inflammatory effects; these activities safely minimize free radical-mediated damage biologically. However, the photoaging mitigation effect of morin on skin cells remains unknown. To investigate the effect of the morin on cell senescence mitigated against photoaging, cell viability, antioxidation, and anti-inflammation experiments were conducted. As a natural result of oxygen consumption, reactive oxygen species (ROS) in the form of harmful superoxides and hydroxyl radicals are generated through an oxidation reaction involving heavy metal cations such as iron. This adversely affects DNA, lipids, and proteins; therefore, organisms have a self-protective mechanism against oxidative stress via enzymes such as catalase (CAT) and superoxide dismutase (SOD), molecules such as glutathione, and proteins such as thioredoxin. Therefore, in this study, the antioxidative and skin protection functions of morin were examined to investigate the possibility of cosmetics.
