The isolation and structure elucidation Of five new oligo-nicotinated sesquiterpene polyesters with a dihydroagarofuran core from Maytenus ilicifolia, named cangorins F, G,H,1 and J [1-5], is described. The strurtures of these compounds, which possessed nicotinyl,benroyl, and areryl groups as esterifying moieties, were elucidaied by $^IH- and ^{13}C$ 수식 이미지-nmrspectroscopic studies, inrlusive of hereronuclear correlation, long-range correlation, and nOespectra, along with mass and cd spectral dara, and the X-ray crystallographic analysis of 1.
