The mol-ecule of O-acetyl-swietenolide, C(29)H(36)O(9), isolated from the seeds of Swietenia macrophylla, features 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 C=C double bond. The furyl substitutent is
The title compound, C(31)H(38)O(10) [systematic name: (αR,4R,4aR,6aS,7R,8S,10R,11S)-methyl α,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][2]benzo-pyran-8-acetate], was isolated from the seeds of Swietenia
To study the chemical constituents from the fruit of Swietenia macrophylla.
The chemical constituents were extracted and isolated by silica gel, Sephadex LH-20. The chemical structures of components were further elucidated by the physicochemical characters and MS,NMR spectral data.
