中文摘要: 目的:研究昆布药材中聚合酚类成分。方法:利用硅胶柱层析、Sephadex LH-20色谱柱等对药材中聚合酚类成分进行分离纯化,根据理化性质和波普数据分析鉴定化合物结构。结果:从昆布药材中共分离得到7个聚合酚类化合物,分别鉴定为间苯三酚(1)、昆布醇(2)、Fucodiphloroethol G(3)、Phlorofucofuroeckol A(4)、1-(3′,5′-dihydro-xyphenoxy)-7-(2″,4″,6-trihydro-xyphenoxy)-2,4,9-trihydroxydibenzo-1,4-dioxin(5)、Dieckol(6)和6,6′-bieckol(7)。结论:化合物5、7均为首次从昆布药材中分离得到,本研究为昆布药材质量评价奠定了一定基础。
英文摘要: OBJECTIVE: To study on the phlorotannins in Ecklonia kurome. METHODS: Silica gel column chromatography and Sephadex LH-20 column chromatography were conducted for isolation and identification of phlorotannins, and the compound structures were analyzed and identified based on physicochemical properties and spectral data. RESULTS: Totally 7 phlorotannins were isolated from E. kurome, namely Phloroglucinol (1),Eckol (2), Fucodiphloroethol G(3), Phlorofucofuroeckol A (4), 1-(3′ ,5′ -dihydro-xyphenoxy)-7-(2″ ,4″ ,6-trihydro-xyphenoxy)-2,4,9-trihydroxydibenzo-1,4-dioxin (5),Dieckol (6) and 6,6′ -bieckol (7).  CONCLUSIONS: Compound 5 and 7 are isolated from E. kurome for the first time, and the study has laid a foundation for its quality evaluation.
