In this study, in vitro antioxidant, antimicrobial, cytotoxic, and cell migration effects of phenolic compounds of leaves, known in the Transylvanian ethnomedicine, were investigated. Ultra-high-performance liquid chromatography-tandem mass spectrometry was employed for the analysis of the ethanolic and aqueous extracts. The antimicrobial properties were determined using a conventional microdilution technique.

The Importance of Pine Species in the Ethnomedicine of Transylvania (Romania).

The geographical and ecological features of Transylvania enable the wide ethnobotanical use of pine species. The aim of this study was to survey the current ethnomedicinal and other traditional use of pine species of Hungarian-speaking ethnic groups in Transylvania and to compare them with earlier reports performed in Transylvania and from other countries related to the Carpathian Basin. Information on pine species was obtained using semi-structured interviews with 515 Transylvanian informants from 18 villages in the period 2007-2019.

Treatment of Benign Prostatic Hyperplasia by Natural Drugs.

Benign prostatic hyperplasia (BPH) is one of the most common urinary diseases affecting men, generally after the age of 50. The prevalence of this multifactorial disease increases with age. With aging, the plasma level of testosterone decreases, as well as the testosterone/estrogen ratio, resulting in increased estrogen activity, which may facilitate the hyperplasia of the prostate cells.

Speciation by triparental hybridization in genus Sorbus (Rosaceae).

Hybridization associated with polyploidization and apomixis is a frequent mechanism of speciation. Sorbus is a genus with ongoing hybridization resulting in a polyploid complex with different parental lineage. Triparens is the smallest hybridogenous subgenus of Sorbus so far known to comprise only two taxa, S.

Calluna vulgaris (L.) Hull belonging to Ericaceae family occurs mostly at sour habitats in subalpine regions in Europe. The species is cultivated in many countries, but it is known as medicinal plant because of polyphenols and aucubin as main compounds.

Cytotoxic, Antimicrobial, Antioxidant Properties and Effects on Cell Migration of Phenolic Compounds of Selected Transylvanian Medicinal Plants.

Medicinal plants are widely used in folk medicine but quite often their composition and biological effects are hardly known. Our study aimed to analyze the composition, cytotoxicity, antimicrobial, antioxidant activity and cellular migration effects of , , and used in the Romanian ethnomedicine for wounds. Liquid chromatography with mass spectrometry (LC-MS/MS) was used to analyze 50% () ethanolic and aqueous extracts of the plants' leaves.

Cytotoxic Action of Artemisinin and Scopoletin on Planktonic Forms and on Biofilms of Species.

We investigated the antifungal activities of purified plant metabolites artemisinin (Ar) and scopoletin (Sc) including inhibition, effects on metabolic activities, viability, and oxidative stress on planktonic forms and on preformed biofilms of seven species. The characteristic minimum inhibitory concentration (MIC) of Ar and Sc against species ranged from 21.83-142.

Impact of tart cherries polyphenols on the human gut microbiota and phenolic metabolites in vitro and in vivo.

Tart cherries have been reported to exert potential health benefits attributed to their specific and abundant polyphenol content. However, there is a need to study the impact and fate of tart cherries polyphenols in the gut microbiota. Here, tart cherries, pure polyphenols (and apricots) were submitted to in vitro bacterial fermentation assays and assessed through 16S rRNA gene sequence sequencing and metabolomics.

The effect of ageing temperature on the physicochemical properties, phytochemical profile and α-glucosidase inhibition of Hibiscus sabdariffa (roselle) wine.

The effect of temperature (6, 15 and 30°C) during ageing on the colour, phytochemical composition and bioactivity of roselle wine was investigated over 12months. At the end of ageing, wines stored at 6°C had the highest colour density and lowest polymeric anthocyanins. The initial concentration of most of the individual phenolic compounds decreased during ageing, with reduction of monomeric anthocyanins contributing to the formation of anthocyanin-derivatives (pyranoanthocyanins), eight of which were identified tentatively and reported here for the first time in roselle wine.

[Health effects of sour cherries with unique polyphenolic composition in their fruits].

Health effects of fruit consumption are confirmed by many studies. Such effects are attributed to the polyphenolic compounds accumulating in fruit skin and mesocarp tissues. They contribute to the regulation on transcriptional, post-transcriptional and epigenetic levels.

A novel luminol-based enhanced chemiluminescence antioxidant capacity microplate assay for use in different biological matrices.

Introduction: Reactive oxygen species (ROS) are normal metabolic products of living cells. However, a decrease of the defense mechanisms against the effects of ROS or increased ROS production maybe one important causative factor of cellular damage. A non-enzymatic scavenger system is considered to be responsible for the maintenance of total antioxidant capacity (TAC) as a protection against oxidative injuries that exist in all higher plants and in mammals as well.

Histological and antimicrobial study of Ononis arvensis L.

In this study field restharrow (Ononis arvensis) was investigated for histological and antimicrobial features. The aerial part and the root were embedded in synthetic resin and investigated following sectioning by a rotation microtome. The antimicrobial activity and minimum inhibitory concentration of the solvent fractions of the aerial part were studied against four bacterial strains and one fungus.

The aim of this study was to survey the current day ethnoveterinary practices of ethnic Hungarian (Székely) settlements situated in the Erdővidék commune (Covasna County, Transylvania, Romania) and to compare them with earlier works on this topic in Romania and other European countries.

Of the importance of a leaf: the ethnobotany of sarma in Turkey and the Balkans.

Background: Sarma - cooked leaves rolled around a filling made from rice and/or minced meat, possibly vegetables and seasoning plants - represents one of the most widespread feasting dishes of the Middle Eastern and South-Eastern European cuisines. Although cabbage and grape vine sarma is well-known worldwide, the use of alternative plant leaves remains largely unexplored. The aim of this research was to document all of the botanical taxa whose leaves are used for preparing sarma in the folk cuisines of Turkey and the Balkans.
