Abstract
Objective To purify the total flavones from Resina Draconis using D101 resin, and set up a method of simultaneously determining the contents of loureirin A and B in the extract. Methods Fractions in 70% and 95% ethanol were collected. Mixture of acetonitrile and l% acetic acid (34.5:65.5) was used as the mobile phase and ODS column was used as stationary phase to determine loureirin A and B. The detecting wave length was 280 nm. Results In the established HPLC method, the linear range of loureirin A was 11.00-275.00 g/ml, and that of loureirin B was 20.00-500.00 g/ml. Linear equation of loureirin A was Y=35 844C+44 725(r=0.999 9) and that of loureirin B was Y=28 533C-41 085, r=0.999 9.The accuracy, precision and stability of this method were satisfactory. Conclusion The proposed method was suitable for preparation of total flavones and determination of its active components from Resina Draconis.
