Objective: To study the chemical constituents of Hippophae rhamnoides L. Seabuckthorn as an edible and medicinal resources to provide experimental basis. Methods: A variety of chromatographic methods for separation and purification, spectral analysis combined with literature to determine the structure of the compound. Results: Eleven compounds were isolated from 95% ethanol extract of seabuckthorn seed, which were: kaempferol-3-O-rutinoside, catechin, epicatechin, Catechin (4), epigallocatechin (5), 6,9-dihydroxy-4,7-megastigmadien-3-one (6), kaempferol (7), quercetin (8) (9), (- sitosterol (10), and pilosula glucoside (11) .CONCLUSION: Compounds 1 ~ 6 were isolated from this plant for the first time.
