Chemical constituents from the fruit of Zizyphus jujuba Mill. var. spinosa

Twenty-one compounds, including ten triterpenoids (1-10), two sterols (11 and 12), six flavonoids (13-18), and three cerebrosides (19-21) were isolated from the fruit of Zizyphus jujuba Mill. var. spinosa (Bunge) Hu ex. H. F. Chou. The structures were elucidated by spectroscopic methods and by comparison of their reported spectral data. These compounds have shown the relationship between this plant and other species from the Rhamnaceae family.
