Chemical composition of sage (Salvia officinalis L.) essential oil from the Rio de Janeiro State (Brazil)

Abstract

ABSTRACT:The purpose of this study was to investigate the chemical composition of the essential oil from fresh leaves of sage (Salvia officinalis L.) from Petrópolis, Rio de Janeiro State, for international trade. The oil was isolated by hydrodistillation in a Clevenger-type apparatus and analyzed through a combination of GC-FID and GC-MS. The yield was 2.3 % on dry basis. Forty-seven constituents were identified according to their chromatographic retention indices and mass spectra, corresponding to 94.90 % of the compounds present. The major constituents of the oil were α-thujone (40.90 %), camphor (26.12 %), α-pinene (5.85 %) and β-thujone (5.62 %). The essential oil studied was similar to those found in several European countries and can be a valuable product for the small farmers from the Petrópolis region in Rio de Janeiro State.Keywords: Lamiaceae, Salvia officinalis, essential oil RESUMO: Composição química do óleo essencial de Salvia (Salvia officinalis) do Estado do Rio de Janeiro (Brasil). O objetivo deste estudo foi investigar a composição química do óleo essencial de folhas de sálvia (Salvia officinalis L.) de Petrópolis, Rio de Janeiro, para o comércio internacional. O óleo foi isolado por arraste a vapor em aparelho de Clevenger e analisado por CG-DIC e CG-EM. O rendimento foi de 2,3 % em base seca. Quarenta e sete substâncias foram identificadas de acordo com seus índices de retenção e espectros de massas, correspondendo a 94,90% dos compostos presentes no óleo. Os principais constituintes do óleo foram α-tujona (40,90 %), cânfora (26,12 %), α-pineno (5,85 %) e β-pineno (5,62 %). O óleo estudado foi similar àqueles encontrados em vários países europeus e pode ser um valioso produto para pequenos produtores da região de Petrópolis no Estado do Rio de Janeiro. Palavras
