Abstract

The title compound, C(19)H(18)O(7), also known as chrysoobtusin, was isolated from Cassia tora L. (Leguminosae). The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 4.27 (4)°. The structure is stabilized by intra- and inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, and by weak π-π stacking inter-actions along the b axis, with a centroid-centroid distance between related benzene rings of 3.800 (4) Å.

摘要

标题化合物C(19)H(18)O(7)，也被称为金决明素，是从决明（豆科）中分离得到的。蒽醌环系几乎是平面的，两个苯环之间的二面角为4.27 (4)°。该结构通过分子内和分子间的O-H⋯O和C-H⋯O氢键以及沿b轴的弱π-π堆积相互作用得以稳定，相关苯环之间的质心距离为3.800 (4) Å。
