Hydrodistillation and Microwave Extraction of Volatile Compounds: Comparing Data for Twenty-One Species from Different Habitats.

Free volatile compounds were isolated from 21 Croatian species studied by hydrodistillation (HD) and microwave extraction (ME) and analyzed by gas chromatography coupled with mass spectrometry. Principal Component Analysis (PCA) distinguished some clusters based on the relative proportion of major compounds, such as hexadecanoic acid, hexahydrofarnesyl acetone, phytol, -caryophyllene, and caryophyllene oxide, which were identified in all species studied by both isolation methods. In addition to these compounds, germacrene D, δ-selinene, and eicosane were also identified in five samples from dry habitats isolated using ME.

Free Volatile Compounds of ssp. (Baumg.) Eb. Fisch. and Their Biological Activity.

The composition of free volatile compounds of essential oils (EO) and hydrosols (Hy) from four different localities of the species ssp. (Baumg.) Eb.

Antioxidant Capacity of Free Volatile Compounds from L. cv. Oblica Leaves Depending on the Vegetation Stage.

Previous research on specialized metabolites of olive leaves has focused on the phenolic components and their biological role. The research in this article focuses on the metabolites that form free volatile compounds (FVCs). The composition of FVCs is divided into compounds isolated in the oil phase (essential oils; EO) and in the aqueous phase (hydrosols; Hy) from leaves of L.

The Content of Biogenic Amines in Croatian Wines of Different Geographical Origins.

Samples of white and red wines produced in two different wine-growing regions, coastal (Dalmatia) and continental (Hrvatsko zagorje) of Croatia, were analysed for biogenic amines content. Biogenic amines content was determined, and its concentration levels were associated with the geographical origin of the wine. Due to its high sensitivity, HPLC method with ultraviolet detector was used, including the derivatisation step with dansyl chloride.

Bioaccumulation of trace metals in mussel (Mytilus galloprovincialis) from Mali Ston Bay during DSP toxicity episodes.

The Croatian National Monitoring Program revealed the presence of Diarrhetic Shellfish Poisoning (DSP) toxicity in Mediterranean blue mussel (Mytilus galloprovincialis) from breeding farms in southern Adriatic Sea through January to June 2011. The mouse bioassay tests (MBA; at the time the official method for DSP toxins) were accompanied by atypical symptomatology in the animals and this caused doubts about the assay results. Consequently, in parallel studies reported here, the concentration of Cd, Cr, Cu, Ni, Pb and Zn in soft tissue of DSP positive and negative mussels samples was determined.
