Abstract
The influence of the flavonoid compounds quercetin and rutin on the photo-oxidation of chloroplast membranes was investigated. Both substances retarded pigment loss and inhibited lipid peroxidation, measured as ethane release. The inhibition of photo-oxidation was independent of the mechanism of initiation. Quercetin and rutin were also found to be able to scavenge singlet oxygen and were degraded in the process. It is proposed that flavonoid inhibition of pigment photobleaching and lipid peroxidation is due to general antioxidative properties of the compounds.
