Three non-alkaloidal constituents, (-)-loliolide as an iridoid, friedelin as a triterpenoid, and ${\beta}-sitosterol$ as a steroid, were isolated by fractional extraction and silica gel column chromatography from the herb of Commelina communis L. (Commelinaceae). The structures of the native components were elucidated on the basis of physical and spectral (UV, IR, PMR, CMR, and mass spectra) data.
