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.
