ABSTRACT
AIM : To set up a method of determinting the contents of four iridoid glycosides in different preparations of Lamiophlomis rotata ( Benth.) kudo.METHODS : The quantitative analysis was carded out on a column of Waters Symmetry by HPLC using a mobile phase of CH_3OH-H_2O under a flow rate of 1.0 mL/min.235 nm was selected as the detective wavelength.RESULTS: The linear ranges were 0.236-1.18 μg for sesamoside,0.440-2.20 μg for shanzhiside methyl ester,0.094-0.470 μg for 7,8-dehydropenste moside、0.750-3.75 μg for 8-O-ace-tylshanzhiside methyl ester.The recoveries of them were all between 96% and 104% ( RSD < 5% ).CONCLUSION: The method is accurate,stable,reliable,and can be used as a quantitative standard for determining the contents of iridoid glycosides in different Duyiwei preparations.
