CRYSTALS OF THE TITLE COMPOUND (SYSTEMATIC NAME: 3β-hy-droxy-olean-12-en-28-oic acid ethanol monosolvate), C(30)H(48)O(3)·C(2)H(5)OH, were obtained from unsuccessful co-crystallization trials. The asymmetric unit contains two symmetry-independent oleanolic acid mol-ecules, as well as two ethanol solvent mol-ecules. Inter-molecular O-H⋯O hydrogen bonds stabilize the crystal packing. In the oleanolic acid mol-ecules, ring C has a slightly distorted envelope conformation, while rings A, B, D and E ...[more]
