Resumo

THE VOLATILE CONSTITUENTS OF PROPOLIS FROM PIAUI.The essential oils of five samples obtained in different regions of the state of Piaui were analyzed by GC-MS.Ninety-one volatile constituents were tentatively identified and eight were positively identified.The principal components obtained from each sample were: 1,8-cineole, exo-fenchol, terpin-4-ol and fenchone (Teresina), α-pinene, caryophyllene oxide, β-pinene and α-copaene (Pio IX), (E)-caryophyllene, α-copaene, α-pinene, caryophyllene oxide and δ-cadinene (Campo Maior), (E)-caryophyllene, α-gurjunene and β-selinene (Pedro II) and (E)-caryophyllene, α-gurjunene, δcadinene and α-copaene (Lagoa de Sao Francisco).The five samples presented differences in the chemical composition of volatile fractions.The studies pointed out the need of characterizing propolis from Piaui by geographic regions and by seasons (drought and rainy periods).
