Objective To establish a method for the detection of chrysin and galangin in propolis health care foods by reversed-phase high pressure liquid chromatography (RP-HPLC). Methods Chrysin and galangin in samples were reflux extracted with methanol in water bath, separated by C18 reversed phase column, and detected at wavelength of 268 nm. Results The recovery of chrysin was 95.6%~100.8% with the relative standard deviations of 1.1%~2.0%, and the recovery of galangin was 95.2%~100.5% with the relative standard deviations of 1.6%~2.8%. Conclusion The method is simple, rapid, accurate and reliable, which could be used for the detection of chrysin and galangin in propolis health care foods.
