Abstract
OBJECTIVE
To study the water-soluble chemical constituents of Taraxacum mongolicum.
METHODS
The chemical constituents were isolated and purified by means of several chromatographic techniques and their structures were elucidated by spectroscopic methods.
RESULTS
Nine compounds were isolated and identified as trans-p-coumaryl alcohol(1), trans-p-coumaryl aldehyde(2),p- hydroxybenzoate (3) , p-hydroxyphenyl-propionic acid (4) , 4-hydroxy-2, 6-dimethoxyphenol-1 -O-β-D-glucopyranoside (5) , protocate- chuic aldehyde(6) ,rutin(7) ,quercetin(8) ,kaempferal-3-O-α-L-rhamnopyranosyl-( 1-6) -β-D-glucopyranoside(9).
CONCLUSIONS
Com pounds 1-6 are isolated from this plant for the first time.
