葛藤与葛根中异黄酮类成分的比较

分析比较了野葛〔Ｐｕｅｒａｒｉａｌｏｂａｔａ（Ｗｉｌｄ．）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

Comparison of isoflavones in stem and root of Pueraria lobata (Willd.) Ohwi

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.
