In ethanol, it can improve the light fastness of pigment preparations, prevent the gradual disappearance or change of aroma, and combine with vitamin E to improve its antioxidant capacity. The inhibition of lipid peroxidation of rutin is related to its enhancement of SOD activity and oxygen radical scavenging. Xia Weimu et al. found that rutin has a strong scavenging effect on O2-, and the removal efficiency of Chemicalbook can reach more than 96%. As a chelating agent of Fe2+, rutin can inhibit the Fenton reaction and the chain reaction of lipid peroxidation and has obvious anti-lipid peroxidation effect.
