To study the chemical compositions of Eucommia ulmoides.
The compounds were isolated and purified from Eucommia ulmoides by silica gel column chromatography, Sephadex LH-20, MPLC packed with MCI gel and semi-preparative HPLC. The structures of these compounds were established on the basis of spectral analyses (1H-NMR, 13C-NMR and MS).
Thirteen compounds were obtained,and their structures were identified as betulin (1), syringin (2), pervoside A (3), glucosyringic acid (4), vanillic acid-beta-glucoside (5), geniposide acid (6), aucubin (7), geniposide (8), pinoresinol-4,4'-di-O-beta-D-glucopyranoside (9), syringaresinol di-O-beta-D-glucopyranoside (10), medioresinol di-O-beta-D-glucopyranoside (11), sucrose (12), and ethyl beta-glucopyranoside (13) on the basis of physical characteristics and spectral data.
Compounds 3 - 5, 12 and 13 are isolated from this plant for the first itme.
研究杜仲的化学成分。
通过硅胶柱色谱、葡聚糖凝胶LH - 20、MCI凝胶填充的中压液相色谱和半制备高效液相色谱从杜仲中分离纯化化合物。这些化合物的结构基于光谱分析（1H - NMR、13C - NMR和MS）确定。
获得了13个化合物，根据物理特征和光谱数据，它们的结构被鉴定为桦木醇（1）、紫丁香苷（2）、杜仲苷A（3）、葡萄糖基紫丁香酸（4）、香草酸 - β - 葡萄糖苷（5）、京尼平苷酸（6）、桃叶珊瑚苷（7）、京尼平苷（8）、松脂醇 - 4,4'- 二 - O - β - D - 吡喃葡萄糖苷（9）、丁香树脂醇二 - O - β - D - 吡喃葡萄糖苷（10）、中肌醇二 - O - β - D - 吡喃葡萄糖苷（11）、蔗糖（12）和β - 吡喃葡萄糖苷乙酯（13）。
化合物3 - 5、12和13首次从该植物中分离得到。
