Özet

Macrophyllosaponin E, a novel cycloartane-type triterpene, has been isolated from the roots of Astragalus oleifolius. The structure elucidation of the compound was achieved by a combination of one- and two-dimensional NMR techniques [H-1-H-1-correlation spectroscopy (COSY), H-1-C-13-heteronuclear multiple guantum correlation spectroscopy (HMQC), and H-1-C-13-heteronuclear multiple-bond correlation spectroscopy (HMBC)] and high resolution electrospray ionization Fourier transformation mass spectrometry (HR-ESI-FT-MS).
