| Summary: | Analysis by Gas Chromatography and Gas Chromatography/Mass Spectrometry of the essential oils obtained from leaves of Echinodorus grandiflorus ("Chapéu de couro") from two different populations (Big Leaves and Small Leaves), collected monthly between September 1998 and December 1999 revealed 17 components. Phytol was the major constituent for both populations. The main sesquiterpene representatives are (E)-caryophyllene, alpha-humulene and (E)-nerolidol.<br>Análise por cromatografia com fase gasosa e cromatografia com fase gasosa acoplada à espectrometria de massas de óleos essenciais obtidos de folhas de Echinodorus grandiflorus ("Chapéu-de-couro") em duas diferentes populações (folhas grandes e folhas pequenas), coletadas mensalmente entre setembro de 1998 e dezembro de 1999, revelou 17 componentes. Fitol foi o constituinte majoritário em ambas populações. Os principais representantes sesquiterpênicos foram (E)-cariofileno, alfa-humuleno e (E)-nerolidol. |
