The contents of luteolin,quercetin and kaempferol in Eupatorium Odoratum Linn were determined with RP-HPLC/PAD method.The chromatographic conditions were chromatographic column HiQ sil C18W,detection wavelength 254 nm for quercetin, 360 nm for luteolin and kaempferol,temperature 30℃,mobile phase CH3OH-H2O-H3PO4(50:49.8:0.2,volume ratio), 1 mL/min flow rate,10 μL injection volume.Analysis sample was prepared by ultrasonic extraction from Eupatorium Odoratum Linn with the following conditions:85% ethanol solution as solvent,ratio of liquid to solid 10:1(mL/g),extraction time 1 h.The results showed good linearity(R2>0.999 0) for the three flavonoids over a range of 0.01×10-3~0.10×10-3 g/mL,and the average recovery yields were 99.601 7%,99.032 6%,and 99.450 8%,respectively.The relative standard deviation(RSD) was less than 2%.The method is simple and efficient for the determination of luteolin,quercetin and kaempferol from Eupatorium odortum Linn with high accuracy.
