标题化合物（系统名1-羟基-1，2-二氢异丁酸3，4-内酯一水合物）C26 H32 O 8·H2O的酯基平面与呋喃平面的二面角为43.06（12）°和56.06（7）°，呋喃平面与酮基的二面角为58.50（9）°。 A/B、B/C和C/D环连接都是输注的。羟基和羰基与水分子之间的分子间O-H-O氢键产生三维结构。
In the title compound (systematic name 1-hydroxy-1,2-dihydroobacunoic acid 3,4-lactone monohydrate), C26H32O8·H2O, the dihedral angles between the planes of the ester groups and the furan plane are 43.06 (12) and 56.06 (7)°, while that between the furan plane and the keto group is 58.50 (9)°. The A/B, B/C and C/D ring junctions are all trans-fused. Intermolecular O—H⋯O hydrogen bonds between the hydroxy and carbonyl groups and the water molecule give rise to a three-dimensional structure.
