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 P-sitosterol and stigmasterol. Their structures were elucidated by spectroscopic analysis. including IR, H-1 and C-13 NMR and MS. All these compounds, except 3. were isolated for the first time in the family.
