| 摘要 | 分析比较了野葛〔Pueraria lobata ( Willd. ) Ohwi〕的藤 (葛藤 )和根 (葛根 )的主要异黄酮类活性成分。从葛藤中首次分离得到 3个化合物 ,经化学方法和光谱鉴定 ,证实为大豆甙元 ( A)、大豆甙 ( B)和葛根素 ( C)。 采用双波长薄层扫描法测定葛藤与葛根中上述 3种异黄酮化合物的含量 ,葛藤中大豆甙元、大豆甙和葛根素的含量分别为 0. 195% , 3. 933% 和 2. 481% ; 葛根中则分别为0. 059% , 0. 714% 和 4. 315% 。 研究结果为葛藤新药源的开发利用提供了科学依据。 |
| Abstract | A comparison study was carried out on the isoflavones in the stem and root of Pueraria lobata (Willd. ) Ohwi. Three compounds were isolated from the stem and identified as daidzein, daidzin and puerarin by chemical and spectrum methods. By means of thin layer chromatographic double-wave scanning, the contents of the isoflavones in stem were daidzein 0. 195% , daidzin 3. 933% and puerarin 2. 481% and in the root respectively 0. 059% , 0. 714% and 4. 315% . This result provides the scientific basis for the development and utilization of the Pueraria stem resource. |
