Sumario:The title compound [systematic name: 9-ethyl-13-hy­droxy-14-methyl-2-(3,4,5-trimeth­oxy-6-methyl­tetra­hydro-2H-pyran-2-yl­oxy)-3,3a,5b,6,9,10,11,12,13,14,16a,16b-dodeca­hydro-1H-as-indaceno[3,2-d][1]oxacyclo­dodecine-7,15(2H,5aH)-dione], C(33)H(50)O(9), was obtained by hydrolysis of Spinosyn A. The fused cyclo­pentene ring adopts a twisted conformation, while the fused cyclo­hexene and cyclo­pentane rings are in envelope conformations with the same C atom at the flaps. In the crystal, mol­ecules are linked by O—H⋯O and C—H⋯O hydrogen bonds into a layer parallel to the ab plane.
