To investigate the chemical constituents of the roots of Mirabilis jalapa. Componds were extracted by petroleum ether and then purified by silica gel column chromatography. Their structures were characterized by NMR. Three chemical compounds were respectively b-sitosterol (I), isopropyl(4-(hydroxymethyl)phenyl) carbamate(II), (E)-methyl 2-(3-methoxypropyl)hexadec-14-enoate (III). Conclusion isopropyl (4-(hydroxymethyl) phenyl) carbamate(II) was first reported in this plant.
