Title: Studies on Quality Control of Polygonum viviparum L.
Abstract: Objective:To establish the effective methods for the quality control of Rhizoma Polygom vivipari.Meth- ods:Gallic acid was identified by TLC.The contents of gallic acid were determined by HPLC,carried on a column of Hypersil C_(18)(250 mm×4.6 mm,5μm)with a mobile phase of methanol-water-phosphoric acid (5:95:0.5),the detection wavelength was at 271 nm,with flow rat at 1.0 mL·min~(-1),the temperature of the column was 30℃.Re- sults: The TLC methods were simple wish strong specificity and good reproducibility.The contents of gallic acid were dertermined by HPLC,with accuracy of the average recoveries of 98.17%(RSD=1%,n=5).Conclusion:These methods can be used for quality control of Rhizaoma Polygom vivipari effectively.
