柴胡皂甙含量的动态变化研究

采用高压液相色谱法和分光光度法测定了不同发育期的栽培和野生南、北柴胡中柴胡皂甙a、d和总皂甙的含量,结果北柴胡含量均高于南柴胡;两种柴胡的栽培品含量高于或接近于其野生品;均以营养期含量为最高。

A Study on Dynamic Variation of Saikosaponin Contents

In this paper both the cultivated and wild Bupleurum chinense and B. scorzonerifolium from northeast China of different growing periods and ages were analyzed for the contents of saikosaponins a and d by HPLC and total saikosaponins by spectrophotometry. The results indicated that the saikosaponin content of B. chinense was higher than that of B. scorzonerifolium, and that the saikosaponin contents of the cultivated species were higher than or almost equal to those of the wild ones. It was also found that both the cultivated and wild B. chinense and B. scorzonerifolium featured the highest contents of saikosaponins in the nutrition-growing period.
