[Studies on the flavonoids from whole herbs of Seriphidium terrae-albae].
OBJECTIVE
To investigate the chemical constituents of whole herbs of Seriphidium terrae-albae.


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


RESULTS
Seven flavonoid compounds were isolated and identified as apigenin, eupatilin, chrysoeriol, quercetin-3, 3'-dimethyl ether, quercetagetin-3, 6-dimethyl ether, quercetagetin-3, 6-dimethyl ether-7-O-beta-D-pyranoglucoside and quercetagetin-3, 6-dimethyl ether-4'-O-beta-D-pyranoglucoside, respectively.


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