Abstract	This thesis firstly describes the chemical composition of the lipid fraction corresponding to the aerial parts, especially leaves of 22 plants, 16 of which are angiosperms, 3 gymnosperms, 1 fern, 1 moss and 1 alga. In these soluble extracts in organic solvents of species belonging to the Mediterranean vegetation have been identified several families of aliphatic compounds such as alkanes, alcohols and carboxylic acids and also alicyclics as terpenes or derivatives of phenol. Thus, new products have been recognized as natural compounds, such as alkylresorcinols and alkylguaiacols in the leaves of tamarisk (Tamarix canariensis) and labdanes as imbricatolic-nor-16, 16-nor-acetylimbricatolic and acetylimbricatolic acids in the needles of the common juniper (Juniperus communis). Other compounds previously described in the literature, are found for the first time in some of the analyzed species. Secondly, four catalan water systems have been characterized: Torrent Salat from Horta d?Avinyo (Bages), sali de Cambrils del Solsones (Solsona), the lamination Lake from Castelldefels (Barcelona) and the Llac de l?Agulla de Manresa (Bages), by analyzing biomarkers in water and sediments. In this regard have been analyzed qualitatively and semiquantitatively compounds as mentioned above. Here, for example, have been identified in the sediment Torrent Salat compounds as alkylguaiacols only described in the tamarisk that can be considered new biomarkers.
