| 摘要: |
| 目的 从北青龙衣醇提取物中分离胡桃苷B并建立了含量测定的方法。方法 利用大孔树脂柱色谱、硅胶柱色谱和反相硅胶柱色谱进行分离纯化，得到胡桃苷B，通过高效液相色谱仪建立了含量测定的方法。结果 经核磁共振谱鉴定胡桃苷B为(4S)-4,5-二羟基-α-四氢萘酮-4-O-β-D-吡喃葡糖苷，高效液相色谱洗脱条件为乙腈-水-磷酸（10∶90∶0.2）。结论 该方法简便可行、重复性好，胡桃苷B可作为北青龙衣的指标成分建立质量控制的方法。 |

| Abstract: |
| OBJECTIVE To isolate juglanoside B and establish its content determination method from the fresh rejuvenated fruits of J. mandshurica. METHODS Juglanoside B was isolated by macro-porous resin chromatography, silica gel chromatography and reverse phase silica gel chromatography. The method of its content determination was established by HPLC. RESULTS Juglanoside B was identified as (4S)-4,5-dihydroxy-a-tetralone 4-O-b-D-glucopyranoside on the basis of NMR analysis. Elution condition by HPLC was MeCN-H2O-H3PO4 (10∶90∶0.2). CONCLUSION The method is simple and has good repeatability. Juglanoside B can be used as indexical component to establish the method of quality control. |
