Members of this family are not only showy ornamentals but they possess significant economical and commercial reputation as well. In addition, various plant parts of several species are widely used as foods and traditional medicines in many parts of the world. OBJECTIVE Chemical analyses o...
Aquatidial, um novo bis-norsesquiterpenóide assimétrico, hipoteticamente derivado da isoemigossipolona, foi isolado da casca externa das raízes de Pachira aquatica (Bombacaceae), juntamente com os compostos conhecidos isoemigossipolona, p-cumarato de triacontila e lupeol. As estruturas do aquatidial e dos demais compostos foram determinadas por análises espectroscópicas (EM-FAB, IV, RMN 1D e 2D...
The phytochemical investigation of the roots of Bombax anceps (Bombacaceae) led to the isolation of one new dihydrobenzodioxine derivative, bombaxoin (1) along with ten known compounds. All structures of the isolated compounds were established by means of spectral analyses. Compound 2 showed the highest antioxidant activity (DPPH), while compound 8 showed the highest potential inhibitors activi...
The macroscopic characters of the whole plant, physical constant values, extractive values, preliminary phyto-chemical tests, fluorescence characters under ultra-violet light after treatment with different reagents of the powdered leaves form the tree of Adansonia digitata linn., [Bombacaceae] were studied to fix some pharmacognostical parameters. Preliminary phytochemical screening on the meth...
The occurrence of Cerambycidae (Lamiinae) was evaluated in trunk and branch samples of cardeiro (Scleronema micranthum), a forest species from the Central Amazon. Samples were exposed to biodegradation for 24 months on the forest soil, during which adults and larvae were collected and their attack was evaluated. From a total of 643 cerambycids collected, 606 were immatures and 37 were adults. T...
