description The title compound, C(30)H(44)O(3) [systematic name: 6aR,6 bR,8aS,9aR,12aR,14bR)-4,4,6a,6;b,8a,14b-hexa­methyl-12-methyl­eneicosa­hydro-3H-phenanthro[1′,2′:6,7]indeno­[2,1-b]furan-3,11(2H)-dione], is a triterpene lactone, which was isolated from di­chloro­methane extract of Elaeodendron trichotomum (Turcz.) Lundell (celastraceae) stem bark. The compound has a lupane skeleton and consists of four fused six-membered rings and two five-membered rings. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds into a three-dimensional network. The configuration of ochraceolide A was proposed based on analogue compounds which belong to the lupane type.
