Bioactive potential of L. essential oil.

The aim of this study was to evaluate the phytotoxic, genotoxic, cytotoxic and antimicrobial effects of the L. essential oil (EO). The biological activity of EO depended on the analyzed variable and the tested oil concentration.

Influence of Extraction Solvent on the Phenolic Profile and Bioactivity of Two Species.

The phenolic composition, as well as the antioxidant and antimicrobial activities of two poorly investigated species, Waldst. and the endemic Vis., were studied.

Use of seed priming to improve Cd accumulation and tolerance in Silene sendtneri, novel Cd hyper-accumulator.

Changes in the environment as a result of industrialisation and urbanisation impact negatively on plant growth and crop production. Cadmium (Cd) is one of the most dangerous metals that enters the food chain, with toxic effects on plants and human health. This study evaluated the potential of Silene sendtneri as a novel hyperaccumulator and the role of seed priming in tolerance and accumulation rate of Cd.

Phenolic compounds and bioactive properties of subsp. (K. Malý) Murb., an endemic plant species.

Detailed analysis of phenolic composition and antioxidant and antimicrobial activities of subsp. (K. Malý) Murb.

Total phenolic and flavonoid contents, antioxidant and antimicrobial activities of Alnus glutinosa (L.) Gaertn., Alnus incana (L.) Moench and Alnus viridis (Chaix) DC. extracts.

The objective of this study was to determine total phenolic and flavonoid contents, antioxidant and antimicrobial activities of methanolic extracts from the leaves and barks of three Alnus species. The phenolic and flavonoid contents of extracts were determined spectrophotometrically using Folin-Ciocalteau and aluminium chloride methods, respectively. In addition, antioxidant activity of the extracts was determined using 1,1-diphenyl-2-picrylhydrazyl radical scavenging method.

Cytotoxic and genotoxic activity of some Helleborus species.

Despite their known toxic properties, various Helleborus species are used as medicaments in folk medicine to treat some diseases and health conditions. As the main mechanism of many cytostatic drugs is based on their cytotoxic activity, there is potential for the toxicity of hellebore to be used in anticancer therapy. This study tested the geno- and cytotoxic effects of extracts of three hellebore taxa (Helleborus odorus, Helleborus multifidus and Helleborus hercegovinus) on meristemic onion (Alliumcepa L.

Antioxidative and antitumor properties of in vitro-cultivated broccoli (Brassica oleracea var. italica).

Context: Broccoli [Brassica oleracea L. var. italica Plenck.

Antioxidant and antiproliferative activities of Helleborus odorus Waldst. & Kit, H. multifidus Vis. and H. hercegovinus Martinis.

This study was undertaken in order to evaluate possible antioxidative and antiproliferative activities of three Helleborus taxa. The dry leaves and roots of three Helleborus taxa were extracted with ethanol and water. A phytochemical evaluation of the selected extracts was performed using spectrophotometric methods and a 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity assay was used for measuring the antioxidative activity of extracts.
