Object To establish an HPLC method for the determination of dehydroxypresenegenin for the quality control of Polygalae tenuifolia Willd. Methods Dehydroxy presenegenin was separated by ODS column (125 mm× 4 mm, 5μm) 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 0.585~11.7μg, 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.
