![]() ![]() Both oils showed higher concentrations of monoterpenoids, but they showed different chemical compositions, whereas cis-ocimene (52%) and Ã-ocimene (19%) were major constituents of plant 1, while limonene (93%) is the major component of plant 2.Este trabalho descreve a investigaÃÃo fitoquÃmica dos extratos das raÃzes de Piper divaricatum (Piperaceae), bem como a composiÃÃo quÃmica volÃtil dos Ãleos essenciais das folhas da espÃcie diÃica Schinus terebinhtifolius Raddi (Anacardiaceae). Fourteen components of plant 1, representing an average of more than 81.0% of the chemical compositions of the oils, were identified and eight compounds of plant 2, representing more than 98,0% in average. The chemical composition of the essential oils from leaves of Schinus terebinthifolius, was analyzed by CG-MS and GC-FID. The structures of all isolated compounds were elucidated by spectroscopic methods, such as ME, IR and INMR, including 1D and 2D experimentals NMR spectroscopy and, comparison with published data for closely related compounds. divaricatum, using classic methods of chromatography on sÃlica gel, yelded an amide, (2E,4E)-pentadienamide, 5-(1,3-benzodioxol-5-yl)-N-(2-methylpropyl)- (piperlonguminine), and two benzoic acid derivatives, 3,4-dy-hidroxy- 5-(2âE,6âZ,10âE)-7â-(hydroxymethyl)-3â,11â,15â-trimethyl-hexadeca-2â,6â,10â,14â- tetraenyl), and the Ãcid 3,4-dyhydroxy-5-(2âE,6âE,10âE)-3â,7â,11â,15â- tetramethylhexadeca-2â,6â,10â,14â-tetraenyl) benzoic, this being reported for the first time in the literature.
