AbstractThe leaf composition of Lygeum spartumL. in total lipids and fatty acids presents a seasonal quantitative variation. The principal components analysis realized in the fatty acids quantified and identified by gas chromatography showed that, in period of estival dormancy, the leaves of Lygeum spartumare characterized by a very low rates in lipids. They are made up primarily of saturated fatty acids of witch the palmitic, stearic and myristic acid are more representatives (group 1). These saturated fatty acids seem, made up a biochemical strategy of adaptation against the hydrous deficit and the extremes temperatures, witch the area of study know. On the other hand, in period of spring growth where the tufts of Lygeum spartumare made up specially of young leaves in the process of growth, we obtained relatively significant rates in lipids with prevalence of the unsaturated fatty acids of which the acids oleic, linoleic and linolenic are most characteristic and set up group 2. |
