The title compound, C28H27O10Cl-CH3OH-H2O, was isolated from Physalis minima. The rigid molecule consists of eight fused rings involving three lactones. The spiro-fused --lactone rings are in half-chair and envelope conformations. The spirofused --lactone rings are fused to a cyclohexene ring, which is in a half-chair conformation. The outermost cyclohexene ring and -lactone rings adopt half-chair and envelope conformations, respectively. Intra- and intermolecular O—H---O, C— H---Cl and C—H---O hydrogen bonds are observed.
