摘要
利用HPLC-ABTS+.在线法对细叶杜香叶中的抗氧化活性成分进行筛选和分析鉴定,结果表明:在细叶杜香甲醇提取物的乙酸乙酯萃取组分中筛选到2种抗氧化活性成分,经质谱和核磁共振波谱分析鉴定为染料木苷和槲皮素。
In this study, antioxidant compounds from Ledum palustre L. leaves were screened and identified by using an online high-performance liquid chromatography （HPLC）-ABTS^＋· screening system. Two antioxidant compounds from the ethyl acetate fraction in methanol extract were obtained. By mass spectroscopy （MS） and nuclear magnetic resonance （NMR） spectroscopy, both compounds were identified as genistin and quercetin, respectively.
