| 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 |
