The complete 1H and 13C assignment of two closely related isomeric triterpenoid derivatives (methyl 2a,3b-di-Oacetylolean-12-en-28-oate and methyl 2a,3a-di-O-acetylurs-12-en-28-oate) is described. In addition to 1D NMR methods, 2D shift-correlated NMR techniques (COSY, NOESY, HMBC and HMQC) were use

The rare alkaloid casimiroedine and its peracetylated derivative both show complex 1 H and 13 C spectra with almost all signals doubled owing to slow rotation about the amide bond. Nevertheless, it is possible, using 2D NMR methods, to assign fully the 1 H and 13 C spectra of the major and minor con
The complete assignment of the proton and carbon NMR spectra for ikarisoside A and epimedoside C from the aerial parts of Epimedium koreanum were achieved using the concerted application of one-and two-dimensional NMR techniques including COSY and HMBC spectroscopy. The parameters previously reporte
