The TLC of them were concordance.They presented the same color fluorescence in the corresponding position at the ultraviolet light(365nm). After the vanillic aldehyde sulphuric acid ethanol solution developed, violet color spots presented at the same place. Reference substance of Polysaccharide presented violet color ,but in the corresponding position the crude and the prepared didn't show the spots . It proves that the chemical constituents of Polygala Root may not have changed after stir-baked with honey.
