ABSTRACT
Object To establish an HPLC method for the determination of dehydroxypresenegenin for the quality control of Polygalae tenuifolia Willd. Methods Dehydroxypresenegenin was separated by ODS column (125 mm ? 4 mm, 5 ?m) with a mobile phase of methanol 0 05% phosphoric acid (74∶26) and detected at a wavelength of 210 nm. Results The calibration curve was linear in the range of 0 585~11 7 ?g,with a correlation coefficient of 0 999 99 . The average recovery was 99 21% (n=5), and RSD=0 25% (n=5). Conclusion The method is simple and accurate, with good repeatability and can be used for the quality control of Polygalae tenuifolia Willd and compound preparations of Radix Polygalae.
