Abstract: To search for new and bioactive minor components from traditional Chinese medicines, a new compound, named jujuphenoside (1), was isolated from the seeds of Ziziphus jujuba var. spinosa (Bunge) Hu. The structure of jujuphenoside was elucidated by spectral and chemical methods, particularly two-dimensional nuclear magnetic resonance analysis. Together with the new compound, 22 known compounds were also isolated and identified from the seeds of Z. jujuba var. spinosa, among which, epiceanothic acid (2) was first obtained from natural resources, whereas compounds 7–16 were first obtained from this plant.

Key words: chemical constituent, jujuphenoside, phenyl glycoside, Rhammaceae, Ziziphus jujuba var. spinosa (Bunge) Hu.
