[Studies on flavonoids of Anaphalis sinica].
OBJECTIVE
To investigate the chemical constituents of Anaphalis sinica.


METHODS
Various chromatographic techniques were employed for the isolation and purification of the constituents. The structures were elucidated by chemical and spectral analysis.


RESULTS
Six flavonoid compounds were isolated and identified as kaempferol, tiliroside, quercetin, quercetin -3-O-beta-D-glucosides, scutellarin, 5,7-dihydroxy-8-methoxyflavone and one pyrone were isolated and identified as helipyrone.


CONCLUSIONS
All of these compounds was isolated from the plant for the first time.
