RP-HPLC同时测定不同根龄虎杖根中虎杖苷和白藜芦醇
摘要
目的:建立反相高效液相色谱法同时测定不同根龄虎杖根中虎杖苷和白藜芦醇含量。方法:采用Kromasil C18(4.6 mm×250 mm
Objective:To develop a reserved-phase HPLC method for the content determination of polygonin and resveratrol in different age root of Polygonum cuspidatum.Method: The analysis was carried out with Kromasil C18(4.6 mm×250 mm
5 μm) column and the mobile phase consisted of acetonitrile-1.0% phosphoric acid aqueous solution(50∶50) at a flow rate of 0.8 mL·min-1.The detection wavelength was 319 nm and the column temperature was set at 30 ℃.Result: The calibration curves were linear within the range of 0.716-7.160 μg(r=0.999 6) for polygonin and 0.740-7.400 μg(r=0.999 8) for resveratrol.The average recoveries were 99.7% for erbascoside and 98.5% for resveratrol.Conclusion: The method is simple
accurate
reproducible and precise
and applicable for the determination of polygonin and resveratrol in different age root of Polygonum cuspidatum.
