[Study on chemical constituents of Herba Cirsii].
OBJECTIVE
To study the chemical constituents from the aerial part of Herba Cirsii.


METHODS
Compounds were isolated by various chromatographic techniques and identified by spectral data.


RESULTS
Eight compounds were obtained. Their structures were characterized as (7R,8S)-dehydroconiferyl alcohol-8,5'-dehydroconiferyl aldehyde-9-O-beta-D-glucopyranoside(I),(7S,8R)-dihydro-dehydrodiconiferyl alcohol-9-O-beta-D-glucopyranoside(II), Isokaempferide-7-O-beta-D-glucopyranoside(III), Quercetin-3-O-beta-D-gluco-pyranoside (IV), Pectolinarin (V), Rutin(VI), Sucrose(VII), beta-sitosterol(VIII).


CONCLUSIONS
Among these compounds, compounds I-IV are isolated from Herba Cirsii for the first time, Compounds first time. I and II as lignan compounds from this genus, are reported for the first time.
