| dc.description.abstract | The compositions of the essential oils from the leaves of three domestic varieties of the guava tree Psidium guajava L. (Paluma, Século XXI and Pedro Sato) and of one wild variety were compared. Essential oils were extracted by steam distillation, the components were identified by gas chromatography coupled to mass spectrometry GC-MS, and the apparent concentrations were determined by gas chromatography with a flame ionization detector. The results demonstrated that the three essential oils contained many common substances with a prevalence of 1,8-cineole, whereas the essential oil of the Paluma variety contained 1,8-cineole (42.68%) as the major constituent, as well as α-terpineol (38.68%). The principal components of the essential oil of the Século XXI variety were 1,8-cineole (18.83%), trans-caryophyllene (12.08%), and selin-11-en-4-αol (20.98%), while those of the Pedro Sato variety and of the wild plant were 1,8-cineole (17.68%) and (12.83%), caryophyllene oxide (9.34%) and (9.09%), and selin-11-en-4-α-ol (21.46%) and (22.19%), respectively. | pt_BR |
| dc.description.resumo | Os óleos essenciais de folhas de goiabeira Psidium guajava L. de três diferentes cultivares (Paluma, Século XXI e Pedro Sato) e da planta silvestre foram analisados a fim de comparar os seus constituintes. O óleo essencial foi obtido por hidrodestilação em aparelho de Clevenger modificado. Para a caracterização e quantificação dos compostos presentes por CG-EM e CG respectivamente. Os resultados mostraram que os três óleos essenciais analisados apresentam inúmeras substâncias em comum com a predominância do 1,8-cineol. O óleo essencial da cultivar Paluma se difere dos demais devido a alta concentração de 1,8-cineol (42,68%) e do α-terpineol (38,68%). No óleo essencial da cultivar Século XXI observase a presença do 1,8 cineol (18,83%), trans-carifileno (12,08%) e o selin-11-en-4-α-ol (20,98%) como majoritários, enquanto que a cultivar Pedro Sato e a planta silvestre apresentaram com o 1,8 cineol com (17,68%) e (12,83%), oxido de cariofileno (9,34%) e (9,09%) e o selin-11-en-4-α-ol com (21,46%) e (22,19%), respectivamente. | pt_BR |
