AB  - In Serbia, citral chemotype of Thymus pannonicus All. (Lamiaceae) can be only found on Mt
Vršačke planine, as dominant form, where is traditionally used for medicinal purposes. To overcome
difficulties in harvesting due to distribution in inaccessible areas, and to prevent possible
overexploitation from its natural habitat, finding the means for alternative cultivation of this plant
for its prospective beneficial use in human health care was set as objective of this study. Efficient
system for in vitro shoot propagation of T. pannonicus was established for the first time. Different
types of auxin (indole-3-acetic acid, IAA; indole-3-butyric acid, IBA; 1-naphthaleneacetic acid, NAA)
were used for testing the process of rhizogenesis in vitro. Best response was detected on IBA and
NAA for rhizogenesis frequency and number of formed roots, respectively. Rooted plants were
successfully acclimatized. In vitro shoots cultivated on PGR free medium (E1) and medium with 1
mg L-1 IAA (E2) were extracted with 80% methanol and analysed by HPLC. Presence of rosmarinic
acid (RA) as dominant component was indicated in both extracts, with E2 containing higher RA
amount (45.116 mg g-1DW). Antimicrobial activity of extracts was tested using broth microdilution
method against nine strains of laboratory control pathogenic microorganisms. Both extracts
exerted significant antimicrobial activity against all tested pathogens with minimal inhibitory concen-
trations (MIC) in the range of 6.25-50 mg mL-1, while E2 was more effective against Gram positive
bacteria (6.25-12.5 mg mL-1). Presented results could give inducement for potential greater
commercial use of this significant species in the future.
