Studies on the Iridoid, Triterpenoid and Steroid Components of Commeline communis

닭의장풀의 Iridoid, Triterpenoid 및 Steroid 성분에 관한 연구(II)

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.
