The title compound, C31H38O10 [systematic name: (R,4R,4aR,6aS,7R,8S,10R,11S)-methyl ,10-di-acet-oxy-4-(3-furyl)-4a,7,9,9- tetra-methyl-2,13-dioxo-1,4,4a,5,6,6a,7,8,9,10,11,12-dodeca-hydro-7, 11-methano-2H-cyclo-octa-[f]benzo-pyran-8-acetate], was isolated from the seeds of Swietenia macrophylla. The mol-ecule contains four six-membered rings connected together in the shape of a bowl; one of the inner rings adopts a twisted chair conformation owing to the carbon-carbon double bond. The furyl substitutent is connected to an outer ring, and it points away from the bowl cavity.
