Abstract Quercetin and quercetin derivatives are strong flavonoid antioxidants. Electrochemical oxidation of quercetin in the presence of 1,2,3,4-di-O-diisopropylidene-α- d -galactopyranose in acetonitrile has been studied using controlled-potential electrolysis, cyclic voltammetry and spectroscopy (UV–vis and LCMS). The results indicate that quercetin undergoes electrooxidation forming 2-(3,4-dihydroxybenzoyl)-2,4,6-trihydroxy-3(2H) benzofuranone and monoglycoconjugate of benzofuranone, subsequently.

在吡喃半乳糖存在下槲皮素的电化学研究：在槲皮素醌/醌甲基化物的电合成糖合物中的潜在应用

摘要 槲皮素和槲皮素衍生物是强类黄酮类抗氧化剂。已经使用控制电位电解、循环伏安法和光谱法（UV-vis 和 LCMS）研究了在乙腈中存在 1,2,3,4-二-O-二异亚丙基-α-d-吡喃半乳糖的情况下槲皮素的电化学氧化。结果表明槲皮素经历电氧化，随后形成 2-(3,4-二羟基苯甲酰基)-2,4,6-三羟基-3(2H) 苯并呋喃酮和单糖缀合物。
