	abstract = {Relationships between soil chemistry and population chemotype structure of Thymus pulegioides have been studied. The analysis of correlations suggest that an increased carbonate content in soil decreases the chemotype diversity of a population (as calculated by use of the Shannon index): the propertion of linalool chemotype plants rises and that of phenol chemotype plants declines. In addition, the chemotype diversity decreases with increasing frequency of linalool chemotype, and increases with increase of carvacrol chemotype.},

	abstract = {The utility of multivariate analysis techniques in the study of infraspecific variability of essential oils is shown through its application to Thymus moroderi and T. antoninae. The composition and chemical polymorphism of their essential oils is investigated. Both taxa showed the same major constituents: 1,8-cineole, camphor, camphene and borneol, but several differences in their sesquiterpene fraction. Chemometric analysis of the oil of individual plants from different populations of the two species showed the existence of two types of essential oils in T. moroderi with different sesquiterpene composition and low degree of chemical polymorphism in the case of T antoninae.},
