Abstract:
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.
