[Studies on the chemical constituents of Portulaca oleracea].
OBJECTIVE
To study the chemical constituents of Portulaca oleracea.


METHODS
The constituents were isolated by column chromatography and identified on the basis of physicochemical and spectral data.


RESULTS
Five compounds were isolated from 70% ethanol extract of this plant and their structures were elucidated as cyclo (Phe-Ile) (1), cycle (Tyr-Ala) (2), adenine (3), friedelin (4) and isoselachoceric acid (5).


CONCLUSIONS
Compounds 1-5 are isolated from Portulaca oleracea for the first time.
