| Abstract: | Aim To study the chemical constituents of the seeds of Ziziphus jujuba Mill var. spinosa (Bunge) Hu ex. H.F. Chou. Methods To separate the constituents by using various kinds of chromatography methods and identify their structures on the basis of spectral analysis. Results 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). Conclusion Compound 1 is a new compound named jujuboside E. Compounds 5, 6, 7 were isolated for the first time from this plant. |
