The effective rapid measurement method to detect the Troxerutin active ingredient in injection Troxerutin was established based on High-Performance Liquid Chromatog. (HPLC).The method could be used in Laboratory Center of the pharmaceutical production enterprises.The optimum conditions were as follows: Zorbax Eclipse XDB-C18 (250×4.6 mm, 5μm) Column (P/N 993967-902/5063-6600) packing column was used at room temperature, and phosphate buffer:acetonitrile = 80:20 was applied as mobile phase in flow rate of 1 mL/min, and 252 nm detection wavelength were chosen by experimentIt provided a new, convenient, rapid, accurate and reliable method for the detection of Troxerutin active ingredient in injection Troxerutin.The method could be used on quality control of troxerutin in the drug manufacturer.
