AB  - This study was performed to determine the main antibacterial compounds of the essential oil (ЕО) of saltmarsh plant Artemisia santonicum (Asteraceae). The combination of HPTLC and direct bioautography was used for the activity guided isolation of isogeranic acid as the main antibacterial constituent with remarkable antimicrobial activity, although it was the minor component of the EO, present only in 0.2 %, as calculated from GC/FID. Its structure was determined by 1D- and 2D-NMR and GC–MS techniques. Antibacterial activity of isogeranic acid against all tested bacteria was significantly higher than EO and even than both controls streptomycin and ampicillin. In further investigation of antibiofilm and antiquorum sensing activity EO exhibited the best inhibition of the biofilm formation at 1/8 minimal inhibitory concentration (MIC) and isogeranic acid at 1/2 MIC. Both EO and isogeranic acid possessed pyocyanin inhibitory activity showing the reduction of pigment at 60.6 and 62.8 %, respectively, at 1/2 MIC concentrations.
AB  - Ово истраживање је спроведено у циљу одређивања главних антибактеријских компоненти етарског уља слатинске биљне врсте Artemisia santonicum (Asteraceae). Комбинација HPTLC методе и методе директне биоаутографије је коришћена за активношћу вођено изоловање изогеранилне киселине као главне компоненте са значајном антимикробном, антибиофилм и антикворум активношћу иако је била присутна у етарском уљу са само 0,2 %, израчунато из GC/FID. Њена структура је одређена 1D и 2D NMR и GC–MS техникама. Антибактеријска активност изогеранилне киселине на све тестиране бактерије је била значајно боља од етарског уља, и од обе контроле, стрептомицина и ампицилина. Етарско уље је показало најбољу инхибицију формирања биофилма у концентрацији 1/8 минималне инфибиторске концнетрације (MIC вредности), а изогеранилна киселина у концентрацији 1/2 MIC вредности. И етарско уље и изогеранилна киселина су имале пиоцијанин инхибиторну активност показавши смањење пигмента на 60,6 и 62,8 %, у концентрацији 1/2 MIC вредности, редом.

In addition, two known secondary metabolites, patuletin3-O-β-D-apiofuranosyl-(1‴→2″)-β-D-glucopyranoside (5) and patuletin 3-O-5‴-Oferuloyl-β-D-apiofuranosyl-(1‴→2″)-β-D-glucopyranoside (6), were isolated for the first time from A. tatarica. The structures of the isolated compounds were elucidated by 1D and 2D NMR, HRESIMS, IR, and UV data. Antibacterial activity by the microdilution method and antibiofilm activity against P. aeruginosa were assessed. Compound 5 possesses significant
antibacterial activity, while the most potent antibiofilm agent is compound 2.

AB  - This paper presents new data for secondary metabolites and biological activity of the insufficiently studied European inland halophytes as remarkable indicators of Balkan saline habitats. Phenolic content, flavonoid concentrations and antioxidant activity were analyzed in fifteen terrestrial salt tolerant plants collected from eight saline habitats situated in two distinct semiarid regions of Serbia. Total phenols ranged from 31.86 to 212.71 mg of GA/g of extract (gallic acid equivalent milligrams of gallic acid per gram of extract). Concentration of flavonoids ranged from 41.21 to 146.06 mg of RU/g of extract (rutin equivalent milligrams of rutin per gram of extract). Antioxidant activity was determined using 1,1-dipheny1-2-picrylhydrazyl radical reagent; obtained values was ranged from 1785.81 to 17.55 mu g/ml. A significant relation was noticed between the concentration of phenols and antioxidant activity. Parallel to the analysis of researched halophytes, Camellia sinensis and Ginkgo biloba were analyzed for comparison. The best antioxidant properties were determined for Statice gmelinii, Artemisia santonicum and Mentha pulegium. The results indicate a potential of studied halophytic species as candidates for natural sources of secondary metabolites with high biological activity, whereas their bioactive compounds might have a significant role in adaptations to salt and drought stress.
