PMID 20218290

Abstract

To study the chemical constituents of Portulaca oleracea. The constituents were isolated by column chromatography and identified on the basis of physicochemical and spectral data. 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). Compounds 1-5 are isolated from Portulaca oleracea for the first time.
