[Isolation and identification of two flavonoids from Taraxacum mongolicum Hand.-Mazz].
OBJECTIVE
To study the chemical constituents of Taraxacum mongolicum.


METHODS
Compounds were separated by column chromatography on silica gel and polyamide, and their structures were determined by spectral analysis and chemical evidence.


RESULTS
Two flavonoid compounds were separated and elucidated as isoquercitrin and hyperin.


CONCLUSIONS
These two compounds were isolated from the plant for the first time.
