To study the chemical constituents of the seeds of Ziziphus jujuba Mill var. spinosa (Bunge) Hu ex. H.F. Chou.
To separate the constituents by using various kinds of chromatography methods and identify their structures on the basis of spectral analysis.
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).
Compound 1 is a new compound named jujuboside E. Compounds 5, 6, 7 were isolated for the first time from this plant.
研究酸枣仁的化学成分。
采用多种色谱方法分离成分，并根据光谱分析鉴定其结构。
分离得到7个化合物。其结构分别鉴定为酸枣仁皂苷E（1）、酸枣仁皂苷B（2）、酸枣仁皂苷A（3）、桦木酸（4）、硬脂酸（5）、蔗糖（6）和肌苷（7）。
化合物1为新化合物，命名为酸枣仁皂苷E。化合物5、6、7为首次从该植物中分离得到。
