Resumo

CHEMICAL CONSTITUENTS OF Bombacopsis glabra (BOMBACACEAE).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), 5hydroxy-3,6,7,4'-tetramethoxyflavone (2), the naphtoquinone isohemigossypolone (3), the ester triacontil p-coumarate (4) besides lupeol and a mixture of β-sitosterol and stigmasterol.Their structures were elucidated by spectroscopic analysis, including IR, 1 H and 13 C NMR and MS.All these compounds, except 3, were isolated for the first time in the family.
