| Abstract: | The concerted application of a variety of one-and two-dimensional NMR techniques to the structural elucidation of the three natural products:latifoliasida Ⅰ,Ⅱ,Ⅲ isolatated from Ilex Latifolia, in C-5D-5N solution are reported. Especially the techniques of 2D NMR(TOCSY,HMQC, and HMBC), let us solve the problem such as the anomeric configuration, linkages between sugar and sugar, between the aglycone and sugar. These spectra provide valuable information for assigning the 13C NMR resonance of this class of compounds. |
