Objective:
To investigate the chemical constituents of Acroptilon repens.
Method:
The ethanol extract of A. repens was isolated and purified by means of chromatography. These compounds were identified by their spectral data.
Result:
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).
Conclusion:
Compounds 5-11 were isolated from A. repens for the first time. Compound 1 is new compounds.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
