叶穗香茶菜甲素（PhyllostachysinA）与DMF包结物的化学计量式为C20H26O6·C3H7ON，用X衍射分析法测定其晶体结构。结晶呈无色透明块状，实验用晶体尺寸为0.6mm×0．6mm×0．8mm，属正交晶系，空间群为P212l2；，晶胞参数为a=10.895（3）、b=13.237（2）和c=15．373（3）A，晶胞体积为V=2217.0（3）A3，晶胞内分子数Z=4，计算晶体密度Dc=1．302gcm－3。应用直接法解析分子结构，以最小二乘法修正结构参数，最终可靠因子Rf=0．060，Rw=0．083。结果表明该结构是由叶稳香茶菜甲素与DMF分子以1：1比例通过氢键包结而形成的隧道型包结物。
The chemical formula of Phyllostachysin A and DMF inclusions was C20H26O6·C3H7ON, and the crystal structure was determined by X-ray diffraction analysis. The crystals are colorless and transparent blocks, and the experimental crystal size is 0.6mm×0.6mm×0.8mm, which is an orthorhombic system, the space group is P212l2; the unit cell parameters are a=10.895(3), b=13.237 (2) and c=15.373 (3) A, the cell volume was V=2217.0 (3) A3, and the number of intramolecular molecules Z=4, and the crystal density was calculated as Dc=1.302 gcm-3. The direct structure was used to analyze the molecular structure. The structural parameters were corrected by the least squares method. The final reliability factor was Rf=0.060 and Rw=0.083. The results show that the structure is a tunnel-type inclusion complex formed by hydrogen bond between phyllocardiolin and DMF molecules in a ratio of 1:1.
