      Agnes M. MORICZ*, G. HORVATH, P. G. OTT (*Plant Protection Institute, Centre for Agricultural Research, Hungarian Academy of Siences, Herman O. Str. 15, 1022 Budapest, Hungary, moricz.agnes@agrar.mta.hu)

      J. Planar. Chromatogr. 28, 173-177 (2015). HPTLC of (1) sclareol, (2) linalool, (3) linalyl acetate, and (4) carvone on silica gel with n-hexane - ethyl acetate 17:3. Detection at UV 254 nm and in daylight after dipping in vanillin - sulfuric acid followed by heating at 110 °C for 5 min. The presence of (1) in Clary Sage essential oil was demonstrated by 2D on silica gel with toluene - ethanol 17:3 in the first direction and n-hexane - acetone in the second direction, and on RP-18 phases with acetonitrile - water 7:3. Bioassays were performed by the direct bioautographic system using a Gram-negative test bacteria (Xanthomanas euvesicatoria), the luminescence gene-tagged Arabidopsis pathogen (Pseudomonas syringae pv. maculicola) and the luminescent marine bacterium (Aliivibrio fischeri) as well as a Gram-positive soil bacterium (Bacillus subtilis). For Xanthomanas euvesicatoria and Bacillus subtilis, the dried layers were dipped into cell suspension culture and after 2 h incubation in a vapor chamber at 28 °C, they were immersed into an aqueous MTT solution. The bright zones against the darker background indicate the presence of antibacterial components. For luminescent bacterial strains, the plate was dipped into bacteria suspension and evaluated with a computer-controlled cooled low-light camera. Images of bioautograms were directly recorded with an exposition time of 5 min for Aliivibrio fischeri and 15 min for Pseudomonas syringae pv. maculicola. The dark spots lacking luminescence indicate the antibacterial activity. Sclareol inhibited all tested bacteria, linalool and carvone showed antibacterial effect against all Gram-negative strains tested, while linalyl acetate only against Xanthomanas euvesicatoria and Aliivibrio fischeri.
