Description
Summary:Qualitative and quantitative analyses of the volatile constituents from resin of Protium heptaphyllum (Aubl.) Marchand subsp. ulei (Swat) Daly (PHU), and Protium heptaphyllum (Aubl.) Marchand subsp. heptaphyllum (PHH), Burseraceae were performed using GC-MS and GC-FID. The resins were collected around the city of Cruzeiro do Sul, state of Acre, Brazil. Essential oils from the two subspecies were extracted by hydrodistillation with a yield of 8.6% (PHU) and 11.3% (PHH); the main components were terpinolene (42.31%) and p-cymene (39.93%) for subspecies ulei (PHU) and heptaphyllum (PHH), respectively.<br>As análises qualitativa e quantitativa dos óleos essenciais obtidos das resinas das espécies Protium heptaphyllum (Aubl.) Marchand subespécie ulei (Swat) Daly (PHU) e Protium heptaphyllum (Aubl.) Marchand subespécie heptaphyllum (PHH), Burseraceae, foram realizadas utilizando cromatografia em fase gasosa acoplado a um espectrômetro de massa (CG-EM) e cromatografia a gás com detector de chama (CG-DIC). As resinas foram coletadas no Município de Cruzeiro do Sul, Acre, Brasil. O óleo essencial das oleoresinas foi extraído por hidrodestilação fornecendo rendimento 8,6% para PHU e 11,3% para PHH. Os monoterpenos terpinoleno (42.31%) e p-cimeno (39.93%) foram os constituintes principais para PHU e PHH, respectivamente.
