[Studies on the chemical constituents in herbs of Hemistepta lyrata].
OBJECTIVE
To investigate the chemical constituents of Hemistepta lyrata.


METHODS
The constituents of the EtOAc-soluble portions of the 95% ethanol extract were isolated and purified by means of chromatography. Compounds were identified by their physical characteristics and spectral features.


RESULTS
Five compounds were isolated and identified as caffeic acid (1), tracheloside (2), uracil (3), 8-carboxymethyl-p-hydroxycinnamic acid (4), and 3-O-p-coumaroylquinic acid (5).


CONCLUSIONS
Compounds 1-5 were isolated from this genus for the first time.
