Free sugars in the leaf, stem and root of Hydrastis canadensis L. were extracted by boiling with 80% aqueous ethanol and characterized by paper chromatography, gas chromatography and various chemical methods.
Alkaline silver nitrate positive substances were detected by paper chromatography; eleven kinds in the leaf, ten kinds in the stem and nine kinds in the root. D-Galactose and a ribitol-like substance seemed to be characteristic components of this plant. In addition, sucrose, D-fructose, D-glucose and inositol were identified.
The ratios of D-glucose: D-fructose: inositol D-galactose: ribitol-like substance in the monosaccharide fraction of the leaf, stem and root were 1:0.78:1.02:0.07:0.01, 1:0.10:0.01:0.02:0.001, 1:1. 39:0.29:0.00:0.02, respectively.
