Objective To develop a vanillin -H2SO4 colorimetry method for the determination of total saponins in Radix Platycodonis samples,in order to provide a scientific basis for the quality control of Radix Platycodonis.Methods With Platycodin D as standard,the total saponins in Radix platycodonis was extracted with soxhlet extractor and purified with macroporous resin column chromatography,its content was determined by vanillin -H2SO4 colorimetry method.Results The calibration curve of total saponins in Radix Platycodonis samples for this method was A=0.003 4C+0.006 4,r=0.999 7.The average recovery and RSD were 96.97% and 1.51%,respectively.The content range of total saponins in Radix platycodonis from different origins was from 1.07% to 3.76%.Conclusion This determination method is practical,reproducible and can be used for evaluating the quality of Radix Platycodonis samples.
