Abstract:
AIMTo study the water-soluble constituents of Echinacea purpurea.
METHODSThe compounds were isolated by chromatography method and their structures were identified on the basis of spectral analyses.
RESULTSFive compounds were identified as 2-(4-hydroxylphenyl)-ethyl-O-alpha-L-rhamnopy-ranoasyl-(1-->6)-beta-D- glucopyranoside, named echipuroside A 1); (6S, 9R)-6-hydroxy-3-one-alpha-inonol-9-O-beta-D-glucopyranoside 2), ampelopsisionoside 3); phenylmethyl-6-O-beta-D-xylopyranosyl(1-->6)-beta-D-glucopyranoside 4) and phyenylmethyl-beta-D-glucopyranoside 5).
CONCLUSIONCompound 1 is a new compound, the others were isolated from this plant for the first time.
