【Abstract】 OBJECTIVE:To establish a method for simultaneous determination of rutin,isoquercitrin,kaempferol-3-Orutinoside,daunorubicin,quercetin and kaempferol in the roots of Tetrastigma hemsleyanum. METHODS:HPLC method was adopted. The determination was performed on Alliance SilGreen C18 column with mobile phase consisted of 0.2% phosphoric acid solution-acetonitrile solution(gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was 360 nm and the column temperature was at 35 ℃. The sample size was 15 μL. RESULTS:The linear range of rutin,isoquercitrin,kaempferol-3-O-rutinoside,daunorubicin,quercetin and kaempferol were 21.77-217.77,12.37-123.75,13.23-132.31,4.63-46.30,5.75-57.50,3.36-33.66 μg/mL(all r=0.999 9),respectively. limit of detection of them were 0.217 8,0.123 8,0.066 2,0.046 3,0.191 7,0.112 3 μg/mL,respectively. limit of quantitation of them were 0.435 6,0.247 5,0.165 4,0.154 3,0.575 0,0.421 2 μg/mL,respectively. RSDs of precision(n=6),stability(24 h,n=7) and reproducibility tests(n=6) were lower than 3.20%. The average recoveries of them were 96.23%,86.88%,97.51%,97.67%,97.50%,87.46%,RSDs were 1.85%,1.90%,1.84%,1.87%,1.25%,2.01%(n=9),respectively. CONCLUSIONS:The method is fast and simple,and could be applied for simultaneous determination of rutin,isoquercitrin,kaempferol-3-O-rutinoside,daunorubicin,quercetin and kaempferol in the roots of T. hemsleyanum.更多还原
