Abstract The subject of this thesis is the study of the components of the essential oils from three species namely, Rosmarinus officinalis L., Origanum dictamnus L. and Cistus creticus ssp. creticus (L.) Greuter et Burdet which are common plants of the flora of Crete. The essential oils contain substances, which originate via the secondary metabolism of plants, and are used for the interaction of the plants with their environment. These components are vital for some basic functions of the plants such as reproduction and protection from insects and parasites. Exploitation of these properties could lead to safer and more environmentally friendly methods for crop protection. The first part of this thesis includes the analysis of the components of the essential oils from the aforementioned plants, the determination of their chemical structure and the classification of each essential oil according to the area of origin. The essential oil, as well as a number of extracts of Rosmarinus officinalis L. in solvents of increasing polarity, were isolated and their components identified and tested by N.AG.R.E.F. (Plant Protection Institute-Heraklion), as biological agents in pest control. In the second part, the elucidation of the structure of a new compound, isolated from the essential oil of the resin from Cistus creticus ssp. creticus (L.) Greuter et Burdet, is presented. This component was initially identified as a labdane analog, namely, 1,1,4a,6-tetramethyl-5-methylene-1,2,3,4,4α,5,8,8α-octahydronaphthalene. Based on the data from one- and two-dimensional NMR spectroscopy the structure of the compound was redefined as that of an eremophilene isomer with the IUPAC name 1,2,3,4,6,7,8,8aoctahydro- 1,8a-dimethyl-7-(1-methylethenyl)naphthalene.
