%X the essential oils obtained by hydrodistillation from samples of propolis manufactured in three regions of rio grande do sul state at brazil, were analyzed through cg, cg-ms and chiral phase gas chromatography (cpgc). these analyses display the presence of samples with elevated essential oil purport, when compared with plants. the yields obtained were until 3.8%. the samples exhibited similar composition, with predominance of the monoterpenes ¦Á-pinene (5763%), ¦Â-pinene (12.5-30.8%) and limonene (1.5-11.2%). in chiral analysis ofthese constituents were observed modifications in the enantiomeric excess of isomers of ¦Á-pinene and limonene in relation with source location of the sample, already in the chiral analysis of ¦Â-pinene were detected only elevated excess of the enantiomer with the (-) configuration. the antimicrobial activity of the crude essential oil was assayed against five bacteria. the best result was obtained against staphylococcus aureus.
