[Studies on chemical constituents of Acroptilon repens].
OBJECTIVE
To investigate the chemical constituents of Acroptilon repens.


METHODS
The ethanol extract of A. repens was isolated and purified by means of chromatography. These compounds were identified by their spectral data.


RESULTS
11 compounds were isolated and identified as 2alpha, 9beta-dihydroxy-dehydrocostus lactone (1) , cynaropicrin (2) , apigenin (3) , stigmasterol (4) , 4' -hydroxywogonin (5) , ethyl caffeate (6) , p-methoxy-cinnamic acid (7) , luteolin (8) , daucosterol (9) , apigenin-7-O-beta-D-glucoside (10) , syringin (11).


CONCLUSIONS
Compounds 5-11 were isolated from A. repens for the first time. Compound 1 is new compounds.
