Ten phenylpropanoic acid esters were isolated from an ethanolic extract of Korean propolis. Their structures were elucidated by spectroscopic methods including NMR and ESI-MS. Caffeic acid esters with catechol moiety exhibited significant ABTS and DPPH radical scavenging activity and protective effect against DNA damage by a Fenton reaction.
从韩国蜂胶的乙醇提取物中分离出10种苯丙酸酯。通过包括核磁共振（NMR）和电喷雾电离质谱（ESI-MS）在内的光谱方法阐明了它们的结构。含有儿茶酚部分的咖啡酸酯表现出显著的2,2'-联氮-双-3-乙基苯并噻唑啉-6-磺酸（ABTS）和1,1-二苯基-2-三硝基苯肼（DPPH）自由基清除活性以及对芬顿反应引起的DNA损伤的保护作用。
