Abstract

Objective:To set up a feasible method of quantitative study about the contents of costunolide in Radix Aucklandiae and Shibaweijiangxiang pills by RP-HPLC.Methods:The conditions were Kromasil column (4.6 mm ×150 mm,5 μm),methanol-water(65:35)as the mobile phase,flow rate was 1.0 mL·min~(-1),wavelength was set at 225 nm.Results:The linear relationship for determination of eostunolide was good in the range of 8-40 μg· mL~(-1),and the recovery rate of costunolide was 99.0%.Conclusion:The method is reliable for the study about the contents of eostunolide in Radix Aucklandiae and Shibaweijiangxiang pills.The method is rapid,simple and accu- rate.
