【Abstract】 Objective: To establish an HPLC method for determination of galangin in propolis.Methods: HPLC method was established.Diamonsil C18 column was used,CH3OH-4%H3PO4 solution(65∶35) as mobile phase,at the flow rate of 1.0 ml/min and the UV detection wavelength at 256 nm.Results: The linear of galangin was 0.00412~0.02472 mg/ml(r2=0.9998).The content of galangin was the highest in the propolis from Shandong(11.7 mg/g). The content of galangin was higher in the propolis from Neimeng and Henan,respecti... 更多还原
