Abstract:Objective To establish the HPLC method to determine the content of luteolin-7-0-glucoside in Yinhuang Capsules.Methods The column: PhenomenexC18 column(250nm×4.6mm,5μm). The mobile phase: acetonitrile-0.5% acetic aqueous; The flow rate :1.0ml·min-1, and the detecting wavelength: 315nm. The column temperature:30℃. Result The linear ranges were 0.20-1.23μg for luteolin-7-0-glucoside. (r= 0.9996).The average recoveries were 98.56% and RSD 1.22%.Conclusion The method was simple, accurate .The quality of luteolin-7-0-glucoside in Yinhuang Capsules can be controlled by the method
Keywords:luteolin-7-0-glucoside  Yinhuang Capsules  HPLC  determination
