The chemical constituents and biological activity of Pinus cembra L. (Pinaceae), native to the Central European Alps and the Carpathian Mountains, are not well known. The aim of the present work was to examine the phenolic content, antioxidant and antimicrobial effects of hydromethanolic extracts of Pinus cembra L. bark and needles. Bark extract had higher(More)
UNLABELLED Cedrus brevifolia (Hook. f.) Henry, a species endemic to Cyprus, has not been studied regarding its constituents and potential biological activities. MATERIAL AND METHODS A crude extract from Cedrus brevifolia bark and its four fractions (diethyl ether, ethyl acetate, n-butanol and aqueous fractions) were investigated regarding their capacity(More)
UNLABELLED The wood of mature Abies alba Mill. (silver fir) trees is used in construction and furniture industries, the bark being the main waste product. AIM This study aimed to investigate possible therapeutic applications of Abies alba bark waste. MATERIAL AND METHODS A raw extract and four extractive fractions were obtained from silver fir bark.(More)
The aim of this study was to investigate the phenolic content and antibacterial activity of the methanol extract from Helichrysum arenarium (L.) Moench subsp. arenarium inflorescences against lower respiratory tract pathogens (standard strains and clinical isolates). The extract was characterised by a total phenolic content of 160.17 mg/g. Several caffeic(More)
The aim of this study is to characterize the content of Aronia melanocarpa Elliott (black chokeberry) extract and also to estimate the influence of polyphenolic compounds contained in chokeberries on oxidative stress, on an L-NAME-induced experimental model of arterial hypertension. The rat blood pressure values were recorded using a CODA Noninvasive Blood(More)
Spirulina is a species of filamentous cyanobacteria that has long been used as a food supplement. In particular, Spirulina platensis and Spirulina maxima are the most important. Thanks to a high protein and vitamin content, Spirulina is used as a nutraceutical food supplement, although its other potential health benefits have attracted much attention.(More)
The dietary flavonoids, especially their glycosides, are the most vital phytochemicals in diets and are of great general interest due to their diverse bioactivity. Almost all natural flavonoids exist as their O-glycoside or C-glycoside forms in plants. The dietary flavonoid C-glycosides have received less attention than their corresponding O-glycosides.(More)
UNLABELLED Since 1989, grapefruit juice is reported to modify, with clinical implications, the pharmacokinetic of a series of drugs such as calcium channel blockers that are dihydropyridine derivates and/or some HMGCoA reductase inhibitors. All these drugs are metabolized to a large extent by the most abundant human isoform of cytochrome P450, CYP3A4.(More)
Lotus is an edible and medicinal plant, and the extracts from its different parts exhibit various bioactivities. In the present study, the hot water-soluble polysaccharides from lotus seeds (LSPS) were evaluated for their cancer cell cytotoxicity, immunomodulatory and antitumor activities. LSPS showed significant inhibitory effects on the mouse gastric(More)
Sesquiterpene lactones are a large group of natural compounds, found primarily in plants of Asteraceae family, with over 5000 structures reported to date. Within this family, genus Artemisia is very well represented, having approximately 500 species characterized by the presence of eudesmanolides and guaianolides, especially highly oxygenated ones, and(More)
