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-fructopyranoside (I), oleanoic acid (II), 3-O-[beta-D-glucopyranosyl], oleanoic acid 28-O-beta-D-glucopyranoside (III), allantoin (IV), 20-hydroxy ecdysone (V), glutamic acid (VI), 3-O-[beta-D-glucopyranosyl], oleanoic acid 28-O-beta-D-glucopyranosyl ester (VII).
Conclusion:
Compounds III-VII were obtained from this plant for the first time.
