The chemical composition of the essential oils obtained from two samples (GP1 and GP2) of Grammosciadium platycarpum Boiss. was analyzed by GC and GC-MS. The analysis of the oils resulted in the identification of twenty-two constituents. Linalool (79.0%-GP1, 81.8%-GP2) and limonene (10.0%, 5.8%) were found to be the major components, respectively. The in vitro antibacterial activities of these ...
This paper concerns the cytogenetic investigation of the Croatian endem ic species Fibigia triquetra (DC.) Boiss. (Brassicaceae). The number of chro mosomes in all investigated cells from three populations of Fibigia triquetra was 2n=2x=!6. Chromosomes were small and ranged from submetacentrics to acrocentrics. One chromosome pair had a relatively small satellite. Although meiosis was not com...

Volatiles from four Astragalus species: phenological changes and their chemotaxonomical application.
This paper shows the changes of the volatile compounds from four Astragalus species at three phenological stages: leaf development, flowering and fructification, which might be connected with the plant defense. After GC/MS analyses of Astragalus glycyphyllos L., A. hamosus L., A. cicer L. and A. spruneri Boiss., different groups of volatile compounds were found: hydrocarbons, alcohols, aldehyde...
The aim of this study was to investigate in vitro antioxidant activity and anti-bacterial activity of the petroleum ether, ethyl acetate and methanol extract obtained from the whole part of Jurinea dolomiaea Boiss (Asteraceae). Total phenolic and flavonoid contents of these extracts were determined as gallic acid and rutin equivalents, respectively. Total antioxidant activity, reducing power of...
