swietenolide/オオバマホガニー

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. 17 compounds were

Natural resources provide more efficient and safer alternatives in managing diabetes compare to the synthetic oral anti diabetes (OAD). The plants not only have hypoglycemic effect, but also prevent its complications; in which no synthetic drugs provide of both
