| Abstract: | Objective To establish an HPLC method for determination of the content and related substances of tetra- acetylated puerarin （TAP）. Methods Agilent XDB- C18 chromatographic column（250 mm ×4. 6 mm,5 μm）was used and the mobile phase consisted of acetonitrile-water（45：55） with a flow rate of 1.2 mL/min. The UV detection wavelength was set at 250 nm. The column temperature was controlled at 30℃. Results The calibration curve was linear within the range of 0. 103 8- 0. 934 2μg, Y= 12 871X-24. 554, r = 0. 999 9 （ n = 7）. The detective limit was 6.65 ng/mL（ S/N = 3）. The mean recoveries was 99.94% （ RSD = 1.32% , n = 9）. The content of related substances of TAP was in the range of 1.02% -1.28%. Conclusion The method is simple,accurate and is applicable for the quality control of TAP. |
