| Abstract: | Taking the rose flower residue as material , The ultrasonic wave and aqueous twophase system coextraction of total flavones from rose flower residue was studied in the thesis. Scavenging effects of rose flower residue on active oxygen species · O2- generated by riboflavine photosensitization and · OH generated by Fenton reaction were investigated by the means of spectrophotometry. The inhibition effects of rose flower residue on the lecithin lipid peroxidation were observed by thiobarbit uric acid spectrophotometry. The results showed that rose flower residue could scavenge active oxygen efficiently. It could also significantly inhibitlipid peroxidation. |
