摘要
The title compound, C40H58O4.CH2Cl2, was isolated for the first time from Bruguiera cylindrica (Rhizophoraceae), and for the first time from natural product resources. The structure contains five fused six-membered rings, with two rings in chair, two in twist-boat and one in a slightly twisted boat conformation. The D and E rings are cis-fused. The feruloyl substituent group is axially attached to the skeleton. O - H ... O hydrogen bonds and C - H ... O interactions are observed in the structure. The absolute configuration was established on the basis of anomalous scattering effects of the solvent.
