【摘要】 自番荔枝(AnnonasquamosaL)种子中分离到3个番荔枝内酯(1～3)。化合物1和2分别是已知化合物bullatacin和annoninⅠ,化合物3系新的间双四氢呋喃环型番荔枝内酯,命名为番荔枝塔亭丙(squamostatinC),经IR、MS、1HNMR及13CNMR谱分析,其结构推定如(3)式。更多还原

【Abstract】 From the seeds of Annona squamosa L., three compounds were obtained, in which compounds 1 and 2 are known compounds, i.e. bullatacin and annonin I, respectively. Compound 3 is a new non-adjacent bis-tetrahydrofuranyl annonaceous acetogenin, named squamostatin C . Based on the analysis of IR,MS, 1H NMR and 13 C NMR spectra, the structure of compound 3 was elucidated as (3).更多还原
