Investigation of the active constituents of portulaca oleraceae L. [portulacaceae] growing in Jordan

The phytochemical analysis of the fresh aerial parts of Portulaca oleracea [Portulacaceae], growing in Jordan, using conventional chromatographic procedures resulted in the isolation of beta-sitosterol, beta-sitosterol-glucoside, N,N'- dicyclohexylurea, and allantoin. The last three compounds were isolated for the first time from this plant. The structure elucidation of these compounds was attained by the use of spectral data [UV, IR, MS, 1H-, 13C- and 2D-NMR], X-ray crystallography and by comparison with authentic samples
