In this paper, 11 monomer compounds were isolated and identified from the ethyl acetate and n-butyl alcohol fractions of ethanol extract from Mesembryanthemum crystallinum L with a variety of column chromatography and spectroscopic techniques. There were two propyl compounds: cis-p-hydroxycinnamic acid (4), ferulic acid (3), two alkaloid compounds: nicotinic acid (6), ethane-1,2-diyl Dinicotinate(7), five glycosides: 2-ethoxy-5-(hydroxymethyl)-tetrahydrofuran-3,4-diol(5), 3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl(E)-3-(4-hydroxy-3-methoxy-phenyl) acrylate(8), (E)-2-(hydroxymethyl)-6-(4-(3-hydroxyprop-1-en-1-yl)-2-methoxyphenoxy) tetrahydro-2H-pyran-3,4,5-triol(9), 6-((1R,2S)-2-hydroxy-4-((S,E)-3-hydroxybut-1-en-1-yl)-3,5,5-trimethylcyclohex-3-en-1-yl)oxy)-5-(hydroxymethyl) tetrahydro-2H-pyran-2,3,4-triol(10),(E)-4-hydroxy-3,5,5-trimethyl-4-(3-((3,4,5-trihydroxy-6-(hydroxymethyl)t) etrahydro-2H-pyran-2-yl)oxy) but-1-en-1-yl) cyclohex-2-en-1-one(11),one phenylpropanone: ryeganolide (2),one steroidal compound: β-sitosterol (1). The study would enrich the research on the chemical constituents in M. crystallinum L. and provide a theoretical basis for the better development of the functional components of M. crystallinum L.

Key words: Mesembryanthemum crystallinum, ethanol extract, chemical compositions, isolation and identification
