Solid-phase microextraction technique (SPME) coupled with gas chromatography (GC-FID and
GC-MS) was used to investigate the inter- and intra-population chemical polymorphism in
volatile constituents of three populations of Thymus pannonicus growing in Slovakia. To have
an idea on what really the plant emits under different environmental and physiological
conditions, a total of 86 individuals were separately analysed using low extraction temperatures
(30°C). Data were analysed using a chemometric approach such as the principal component
analysis (PCA) which revealed a significant intra-population variability with the existence of up
to four chemotypes: the most abundant is the p-cymene/γ-terpinene chemotype, followed by the
geraniol and linalool chemotypes, and, only in one population, by the γ-muurolene/(E)caryophyllene chemotype. This differentiation of individual plants inside the populations allows
better adaptation to ecological conditions of localities and is probably connected with intrinsic
genetic diversity of the species.
Keywords: Thymus pannonicus, SPME, GC, PCA, chemotypes
Table S1. Collection localities of Thymus pannonicus in Slovakia and their climatic and soil chemistry characteristics. All vouchers to samples are deposited in KO (Herbarium
of Botanical Garden, P. J. Šafárik University, Košice, Slovakia). Climatic regions are defined according to Quitt (1971, see below) and soil chemistry data are adapted from
Grejtovský et al. (2000) as follows: locality TPD is locality 33 in Grejtovský et al (2000); locality TPP is 32 and TPK is 6. Abbreviations: pH KCl – pH measured in 1 M KCl,
pHH2O – pH measured in H2O, Cox[%] – content of oxidisable carbon, Nt[%] – content of total nitrogen, CaCO3[%] – carbonate content and contents of available nutrients
[mg.kg-1]: P - phosphorus, K – potassium, Ca - calcium, Mg - magnesium, Na - sodium. * - climatic regions: T1 - warm region, summer long, warm and dry, winter short, mild
up to moderately cold, dry up to very dry; mean January temperature: -3 to -5°C, mean July temperature: 17-19°C, sum of precipitation in summer: 350-400 mm; sum of
precipitation in winter: 200-300 mm; number of sunny days: 50-60; T3 - warm region, summer very long, very warm and dry, winter short, mild, dry up to very dry; mean
January temperature: -3 to -4°C, mean July temperature: 19-20°C, sum of precipitation in summer: 350-400 mm; sum of precipitation in winter: 200-300 mm; number of sunny
days: 60-70.

Compounds are listed in order of their elution from a HP-5 column; for identification methods see Experimental Part. b Retention index on HP-5 column, experimentally determined using
homologous series of C8-C30 alkanes. c percentage values are means of three determinations. d tr, traces (mean value below 0.1%).
