【 摘 要 】

The chemical study of the barks of the stem and roots of Bombacopsis glabra (Bombacaceae) led to the isolation and identification of 5-hydroxy-3,7,4'-trimethoxyflavone (1), 5-hydroxy-3,6,7,4'-tetramethoxyflavone (2), the naphtoquinone isohemigossypolone (3), the ester triacontil p-coumarate (4) besides lupeol and a mixture of beta-sitosterol and stigmasterol. Their structures were elucidated by spectroscopic analysis, including IR, ¹H and 13C NMR and MS. All these compounds, except 3, were isolated for the first time in the family.
