摘　　要：银莲花素,C_(10)H_(8)O_(4),是无色透明晶体,属正交晶系,空间群D_(2h)^(15)-P2_(1)/b2_(1)/c2_(1)/a,晶胞参数:a=11.063(4),b=11.633(4),c=13.873(4)A,Z=8。实验结果表明化合物中两不饱和γ-内酯是以螺环形式与环丁烷相连,与光谱结果一致。The crystal of anemonin,C_(10)H_(8)O_(4),which is colorless and transparent,belongs to orthogonal system with space group D_(2h)^(15)-P2_(1)/b2_(1)/c2_(1)/a,The unit cell parameters are a=11.063(4),6=11.633(4),c=13.873(4)A,Z=8.The diffractometry result shows that the two unsaturated γ-lactone rings are connected to cyclobatane at 1,2 positions in a spire arrangement.It is the same as the result of spectra determination.
