Objective To study the polyphenols from the leaves of Olea europaea. Methods The polyphenols from ethyl acetate fraction were separated and purified by silica chromatographic method and identified by spectroscopic analysis. Results In combination with the data from literatures, the structure of 15 polyphenols had been elucidated on the basis of various spectroscopic methods, including tyrosol (1), hydroxytyrosol (2), hydroxytyrosol acetate (3), 1H-2-benzopyran-6,7-diol (4), 3,4-dihydroxyl-benzoic acid (5), 3-methoxyl-4-hydroxyl benzoic acid (6), isorhamnetin (7), eriodictyol (8), taxifolin (9), quercetin (10), luteolin (11), ligstroside (12), oleuropein (13), apigenin-7-O-glucoside (14), and luteolin-7-O-glucoside (15). Conclusion Compounds 4-9 are isolated from this plant for the first time.
