Characterization of the Portuguese-Grown Cistus ladanifer Essential Oil

Abstract The chemical composition of the cistus oil from Portuguese-grown rockrose (Cistus ladanifer) was determined using GC and GC/MS. A comparison was also made in terms of the geographical source and use of either dry or fresh plant material. The cistus oil herein obtained was richer in amber-like compounds and had a low content of monoterpenes when compared to the usual values found in the literature. Moreover, it presented a relatively high content of ambrox (amber odor), which usually is only reported in labdanum oil. The major constituents were three sesquiterpene alcohols: viridiflorol (13.6–17.4%), globulol (3.1–5.0%) and an unknown sesquiterpene alcohol (2.7–6.0%), as well as the diterpene alcohol 15-nor-labdan-8-ol (1.7–5.2%). Three samples of commercially available cistus oil were also analyzed and compared.

Characterization of Portuguese-Grown Geranium Oil (Pelargonium sp.)

Abstract The chemical composition of the Portuguese-grown geranium essential oil (Pelargonium hybrid) cultivated in northern Portugal, which also grows wild, was examined. It was found that the geranium oil herein obtained had characteristics intermediate between Bourbon and China types, with good olfactory quality and presenting characteristics different from those previously studied. The essential oils of fresh/dried and green/yellow geranium leaves were compared. Solvent extraction methods were also employed and the composition of the respective absolutes was determined and compared with the essential oil. It was concluded that using air-dried plant and yellow leaves improved the quality of geranium oil. Moreover, the absolute obtained from a diethyl ether extract had the best organoleptic properties of the extracts studied.

TRAJETÓRIAS DE MULHERES NO ESPORTE EM PORTUGAL: ASSIMETRIAS, RESISTÊNCIAS E POSSIBILIDADES

Fundamentada no aporte teorico dos estudos de genero, esta pesquisa efetivou-se atraves da realizacao de entrevistas com 21 mulheres atletas e ex-atletas atuantes nas funcoes tecnicas e diretivas no esporte de Portugal. Emergiram tres unidades de significados cuja analise permite identificar avancos na ampliacao da participacao das mulheres no campo esportivo, ainda que, para que se mantenha, seja necessario que as mulheres diversifiquem funcoes e aceitem condicoes de trabalho diferenciadas daquelas oferecidas aos homens. Rejeitando a posicao de vitimas, as entrevistadas transformam as assimetrias em desafios e sugerem acoes para incentivar, ampliar e consolidar a participacao feminina em todas as esferas de competencia esportiva

Educação Física, Desporto e Género: o caminho percorrido na Faculdade de Desporto da Universidade do Porto (Portugal)

Em Portugal, a inclusao do desporto nos estudos de genero e relativamente recente. A investigacao em ciencias do desporto ainda nao conferiu a devida importância ao caracter estruturante do genero nas praticas fisicas e desportivas. Sao, assim, escassos os estudos, teoricos e empiricos, que conjuguem genero e desporto. Neste trabalho pretendemos fazer o levantamento dos diferentes tipos de producao academica no âmbito do desporto, da Educacao Fisica e genero, realizados na Faculdade de Desporto, entre os anos 2001 e 2005.
