Abstract:
Objective: To establish an HPLC method for the determination of gastrodin, prim-O-glucosylcimifugin, 5-O-methylvisammioside, imperatorin and isoimperatorin in Yuzhen powder.Methods: A Phenomenex Gemini C18 column(250 mm×4.6 mm, 5μm) was used and the column temperature was 25℃.The flow rate was 1.0 ml·min-1 and the mobile phase consisted of methanol-water with gradient elution.The detection wavelength was 230 nm and the sample size was 5 μl.Results: The linear range of gastrodin was 2.68-214.0 μg·ml-1(r=0.999 9), and the average recovery was 100.2%(RSD=0.9%, n=6);the linear range of prim-O-glucosylcimifugin was 5.22-418.0 μg·ml-1(r=0.999 7), and the average recovery was 99.9%(RSD=0.9%, n=6);the linear range of 5-O-methylvisammioside was 4.57-365.8 μg·ml-1(r=0.999 5), and the average recovery was 99.7%(RSD=1.0%, n=6);the linear range of imperatorin was 5.22-417.2 μg·ml-1(r=0.999 6), and the average recovery was 99.0%(RSD=0.9%, n=6);the linear range of isoimperatorin was 5.29-423.2 μg·ml-1(r=0.999 8), and the average recovery was 100.2%(RSD=0.8%, n=6).Conclusion: The method is simple and accurate, and the contents of the five ingredients can be determined simultaneously.The method can be used for the quality control of Yuzhen powder.
