The asymmetric unit of the title compound, C(22)H(26)O(8), contains two crystallographically independent mol-ecules with closely comparable conformations (r.m.s. overlay = 0.54 Å for 30 non-H atoms). All six-membered rings display chair conformations, with a slight distortion for the lactone ring. The mol-ecules are connected by O-H⋯O hydrogen bonds into chains along [010], with the independent mol-ecules segregated into separate chains. The two mol-ecules in the asymmetric unit face each other in a head-to-tail fashion, with the furan ring of one mol-ecule turned towards the carboxylic acid terminal of the other mol-ecule.
