[Studies on the chemistry of two new compounds of Hemistepta lyrata].
OBJECTIVE
To study the chemical constituents of Hemistepta lyrata.


METHODS
To separate compounds with various chromatography technology and to elucidate their structures by chemical and spectral analysis.


RESULTS
Two compounds were isolated from Hemistepta lyrata and their structures were determined as hemiceramide (I), hemisterpene ether (II).


CONCLUSIONS
Compounds I and II are new compounds.
