RESUMO

<p><b>AIM</b>To study the chemical constituents of the seeds of Ziziphus jujuba Mill var. spinosa (Bunge) Hu ex. H.F. Chou.</p><p><b>METHODS</b>To separate the constituents by using various kinds of chromatography methods and identify their structures on the basis of spectral analysis.</p><p><b>RESULTS</b>Seven compounds were isolated. Their structures were established as jujuboside E (1), jujuboside B (2), jujuboside A (3), betulic acid (4), stearic acid (5), sucrose (6) and inosine (7).</p><p><b>CONCLUSION</b>Compound 1 is a new compound named jujuboside E. Compounds 5, 6, 7 were isolated for the first time from this plant.</p>
