Influência do armazenamento de folhas secas no óleo essencial de patchouli (Pogostemon cablin Benth.) (original) (raw)

Recebido em 30/7/09; aceito em 18/2/10; publicado na web em 10/6/10 STORAGE INFLUENCE OF DRIED LEAVES ON PATCHOULY (Pogostemon cablin Benth.) ESSENTIAL OIL. The aim of this work was to evaluate the influence of five storage times of dry leaves of two patchouli genotypes on its essential oil content and chemical composition. Harvest was realized four months after planting. Storage influenced essential oil content of genotype POG-002. Patchoulol was the majority compound. Storage of dry leaves increased significatively the content of the compounds α-bulnesene and germacrene A of genotype POG-021 and longicanfenilone, pogostol and patchoulol of POG-002. However, storage reduced significatively the content of the compounds cicloseichelene, β-cariofilene, α-guaiene, acifilene and α-bulnesene of the essential oil of genotype POG-002.
