Objective To establish an pre -column derivation HPLC method for the determination of hyodeoxycholic acid in Qingkai Xiaoyan Tablets. Methods After With 0.1 % 18-crown ether-6-acetonitrile as the catalyst, thed-erivation of hyodeoxycholic acid was induced by 0.6 % 1-(2-bromoacetyl)-p-nitophenylacetonitrile. After derivation, the sample was separated at 35 ℃ on a Waters Symmetry~(R) 5C_(18) (250 mm × 4.6 mm, 5 μm) eluted with acetonitrile and water (60 : 40). The detection wavelength was 254 nm, and the velocity of flow was 1.0 mL·min~(-1). Results The compound was resolved and the negative sample showed no interference, and the linear relationship of hyodeoxycholic acid was excellent. Conclusion The method was simple, rapid, precise and with good reproducibility. This method can be uses to detect the content of hyodeoxycholic acid in Qingkai Xiaoyan Tablets.
