The structure of jujuphenoside was elucidated by spectral and chemical methods, particularly twodimensional 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.展开更多
