ABSTRACT
Objective To establish the preparation techniques for preparing the reference substance of platycodin-D.Methods Raw material of platycodi radix was extracted with 70 %MeOH.The concentrated extract passed through D101 macroporous resin column,then the 40 %alcohol eluate was separated by silica gel column chromatography with chloroform-methanol gradient elution.The fractions contained platycodin-D were collected and purified by HPLC.Results HPLC analysis and normalization of peak areas showed the purity of the platycodin-D was 98.8 %.Conclusions The preparation techniques are simple and high yield,can be used for preparing the reference substance of platycodin-D.
