	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.},

	abstract = {Qualitative and quantitative analysis of the essential oil of Thymus willkomii showed linalool, alpha-terpinyl acetate and 1,8-cineole as major constituents. Chemometric investigation of the infraspecific variability of the essential oil of a population of this species led to the differentiation of two main chemotypes; type A: linalool (49\% of the plants) and type B: alpha-terpinyl acetate (36\% of the plants). The remaining plants (15\%) could not be included in either of these two types; some of them showed significant amounts of other constituents such as trans-sabinene hydrate, myrcen-8-ol, and terpinen-4-ol.},
