COMPOSIÇÃO QUÍMICA DAS CASCAS DAS RAÍZES E FLORES DEPoincianella pyramidalis (Fabaceae)
Chemical investigation of the MeOH extract of root barks of P. pyramidallis (Tul.) L. P. Queiroz resulted in the isolation of 3,3'-dimethylellagic acid and 3,3'-dimethylellagic acid-4'-O-β-D-xyloside. Lupeol, β-sitosterol/stigmasterol and the mixture of fatty acid methyl ester derivatives were also obtained. Chromatographic procedures of the MeOH extract of the flowers of this species led to obtain an unusual mixture of fatty alcohols, β-sitosterol/stigmasterol, α-amyrin, β-amyrin and methyl gallate. The structures of the isolates were established by spectral data analysis. This is the first occurrence of 3,3'-dimethylellagic acid, 3,3'-dimethylellagic acid-4'- O-β-D-xyloside and free fatty alcohols in the Fabaceae family.
