Objective: To study the water-soluble chemical constituents in root of Achyranthes bidentata. Method: The chemical constituents were isolated by silica gel column chromatography and the structures were elucidated by the NMR spectra and physico-chemical properties. Result: Seven compounds were obtained and identified as n-butyl-beta-D-fuctopyranoside ( I ), oleanoic acid ( II ), 3-0-(beta-D-glucopyranosyl), oleanoic acid 28-0-beta-D-glucopyranoside ( III ), allantoin ( IV ), 20-hydroxy ecdysone ( V ), glutamic acid ( VI ), 3-0-(beta-D-glucopyranosyl), oleanoic acid 28-0- beta-D-glucopyranosyl ester ( VII ). Conclusion: Compounds III - VII were obtained from this plant for the first time.
