另外几种断链抗氧化剂α-生育酚、芦丁和虾青素在葵花籽油、亚油酸甲酯O/W乳状液和磷脂脂质体中对槲皮素的抗氧化作用有不同程度的影响。在三种脂类体系中，槲皮素的抗氧化性优于或相当于α-生育酚。α-生育酚在乳剂中对槲皮素有较强的协同作用，在脂质体中的协同作用较弱，在净油中有明显的拮抗作用。虾青素在纯油或脂质体中没有任何作用，但在乳剂中有一些影响，并不影响作为抗氧化剂的槲皮素。芦丁只在与槲皮苷有明显协同作用的脂质体中作为抗氧化剂有效。根据脂质底物的结构组织，对槲皮素与其他抗氧化剂的相互作用进行了分类。(C)2006爱思唯尔有限公司。保留所有权利。
Antioxidative effect of quercetin was affected differently in neat sunflower oil, in methyl linoleate o/w emulsion and in phospholipid liposomes by the other chain-breaking antioxidants, alpha-tocopherol, rutin and astaxanthin. Quercetin was better than or comparable to alpha-tocopherol as an antioxidant in the three lipid systems. The presence of alpha-tocopherol showed a strong synergistic effect for quercetin in the emulsion, less in the liposomes and a clear antagonistic effect in the neat oil. Astaxanthin, without any effect alone in neat oil or in the liposomes, but with some effect in the emulsion, did not affect quercetin as an antioxidant. Rutin was only effective as an antioxidant in the liposomes where rutin showed clear synergism with quercetin. The interaction of quercetin with the other antioxidants is classified according to the structural organisation of the lipid substrate. (c) 2006 Elsevier Ltd. All rights reserved.
