A sensitive and specific high performance liquid chromatography (HPLC)method is developed to determine three anthraquinones,Rhein,Emodin and Chrysophanol,in Polygonum Multiflorum.The three compounds are obtained by ultrasonic extraction,separated on Phenomenex C18 (250 mm×4.6 mm,5μm)with a mixture of methanol -0.4% HAC (volume ration 80:20)as mobile phase at flow rate 0.8 mL/min.The UV detective wavelength is 254 nm,and the column temperature is set at 35 ℃. Result:The calibration curves for Rhein,Emodin and Chrysophanol are linear between 0.0001~12.50μg/mL (r=0.99996),0.0002~25.00 μg/mL (r=0.99999)and 0.00018~22.50 μg/mL (r=0. 99993),respectively.The limits of detection (LOD)are 0.073 ng/mL,0.0282 ng/mL and 0.0871 ng/mL,respectively.The recoveries of the three compounds range are between 88.39%~107.2%.The re-sults indicate that the proposed method is simple,rapid,accurate,sensitive,and low cost,thus it pro-vides an effective scientific means for assaying anthraquinones in Polygonum Multifloru.
