Composition and antimicrobial activity of essential oil from the underground parts of Laserpitium zernyi Hayek (Apiaceae)

Laserpitium zernyi Hayek is Scardo-Pindic endemic plant distributed in the mountain regions of C. Balkans. It was treated earlier as a subspecies, L. siler L. subsp. zernyi (Hayek) Tutin [1,2]. Root of L. siler is traditionally used as tonic, diuretic, emenagogue, in gynecology and externally for toothache treatments [3]. Composition and antimicrobial activity of essential oil from the underground parts (roots and rhizomes) of L. zernyi were investigated. Air-dried and powdered plant material was hydrodistilled using n-hexane as a collecting solvent. Pale blue oil yielded 1.2l% (w/w). The essential oil was analyzed by GC/FID and GC/MS. Forty-three compounds were identified (94.3% of total oil). Oil was characterised by similar content of monoterpenes and sesquiterpenes (52.9% and 41.4%, respectively). The main constituents were α-pinene (3 1.6%) and α-bisabolol (30.9%). The antimicrobial activity was tested using the microdillution method [4] against Gram(+) bacteria Staphylococcus aureus ATCC 25923, S. epidermidis ATCC 12228, Micrococcus luteus ATCC 9341, Enterococcus faecalis ATCC 29212, Gram(-) bacteria Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae NCIMB 9111, Escherichia coli ATCC 25922, and two strains of yeast Candida albicans (ATCC 10259 and 24433). Laserpitium zernyi oil showed significant antibacterial activity against Staphylococcus epidermidis (MIC 31.83 µg/ml), S. aureus and Micrococcus luteus (MICs 63.67 µg/ml). For all other tested microorganisms MIC values were higher than 100.00 µg /ml. The studied essential oil isolated from the underground parts of L. zernyi had a remarkably different composition than the previously tested oils from flower and herb of this plant, and also showed a much higher antimicrobial activity [5].The 80th anniversary of the publication of Turrill’s “Plant life of the Balkan peninsula

This paper represents the fourth part of the inventory of the flora of Serbia (Niketić et al. 2018, 2020, 2021), which contains nomenclatural, taxonomic and floristic notes related to taxa from the Magnoliopsida group. At the same time, this contribution is the basis for publication of subsequent volumes of the An annotated checklist of vascular flora of Serbia in order to supplement the data on vascular plants in our country.У раду је предложено пет нових номенклатурних комбинација, а поред тога, представљено је 17 таксона (врста, подврста и хибрида) васкуларне флоре који су нови за флору Србије (од тога 12 аутохтоних и пет алохтоних биљак). Потврђени су стари или непоуздани наводи за две аутохтоне биљке у флори Србије. У последњем делу рада дате су информације о деветнаест таксона чије је присуство у Србији или у њеним територијалним јединицама оповргнуто.This paper represents the fourth part of the inventory of the flora of Serbia (Niketić et al. 2018, 2020, 2021), which contains nomenclatural, taxonomic and floristic notes related to taxa from the Magnoliopsida group.

Floristic characteristics of Kobilica ridge, Šar planina mt.

Kobilica is a ridge of the Šar Mountains located in the far south of Serbia over which the international border with FYR Macedonia stretches. Numerous factors - being located in the central Balkan area, refugial character, diverse environmental conditions and habitat types, have caused the high level of floristic diversity in the Šar Mountains area, and therefore Kobilica. The vegetation is characterized primarily by acidophilic grasslands (alpine, subalpine and Oro-Moesian), shrub habitats (arctic, alpine and subalpine) and low open shrub-grass calciophilic formations (alpine and subalpine, Illyrian-West Moesian and Moesian-North Scardo-Pindic). The basic phytogeographic and ecological analysis included 955 taxa which were recorded in the area of Kobilica between 2002 and 2008 (663 newly discovered and 292 confirmed taxa from findings in literature). The presented list of flora relates to 907 species for which there are herbarium specimens deposited in two Herbariums (Herbarium of the Institute of Botany and Botanical Garden 'Jevremovac', University of Belgrade - BEOU and Herbarium of the Institute for Nature Conservation of Serbia - INCS)

The paper proposes eight new nomenclatural combinations and indicates two new synonyms. There are 11 taxa (species and subspecies) of the vascular flora that are new for the flora of Serbia (of which nine are autochthonous and two allochthonous plants). Two autochthonous species were confirmed for the flora of Serbia. Six plant taxa are a novelty for proper Serbia, Vojvodina, or Kosovo and Metohija. There are eight taxa whose presence in Serbia or in its territorial units has been refuted.У раду је предложено осам нових номенклатурних комбинација и назначена су два нова синонима. Поред тога, представљено је 11 таксона (врста и подврста) васкуларне флоре који су нови за флору Србије (од тога девет аутохтоних и две алохтоне биљке). Потврђено је и присуство две васкуларне биљке за флору Србије. Шест биљних таксона представљају новину за ужу Србију, Војводину или Косово и Метохију. Такође је присуство неких таксона у Србији или у њеним територијалним јединицама оповргнуто
