description The title compound [systematic name: (3bS,5aS,7R,8R,10aR,10bS)-7-meth­oxy-10b-methyl-3b,4,5,6,7,8,9,10,10a,10b,11,12-dodeca­hydro-5a,8-methano-5aH-cyclo­hepta­l[5,6]naph­tho[2,1-b]furan-7-methanol], C(21)H(30)O(3), was isolated from the beans of Coffea robusta. The mol­ecule contains five fused rings including a furan ring. The two six-membered rings are in chair conformations, but the third six-membered ring and the five-membered aliphatic ring adopt envelope conformations. Inter­molecular O—H⋯O hydrogen bonding is present in the crystal structure.
