Mikanin-3-O-suIfate (1), in the form of its potassium salt, together with mikanin (2) and alpinetin (3) were isolated from Mikania micrantha. The crystal structures of K(1)・CH_3OH, 2 and 3・H_2O were established by X-ray crystallography. The potassium ions in K(1)・CH_OH are bridged by O5, O7 and O8 to form a chain of facesharing KO_8 coordination polyhedra, from which the aglycon units are outstretched to form a polymeric molecular column. Adjacent molecular columns are linked by π-π stacking between parallel, intercalating aglycon units to form layers matching the (101) family of planes, which are further interconnected into a three-dimensional supramolecular assembly. Sulfation at 3-OH induced better co-planarity and conjugation of the rings.
