Among natural substances widespread in fruits, vegetables, spices, and medicinal plants, flavonoids organic acids belong to the promising groups of bioactive compounds with strong antioxidant anti-inflammatory properties. The aim present work was evaluate antibacterial activity 13 common (flavones, flavonols, flavanones) 6 (aliphatic aromatic acids). minimal inhibitory concentrations (MICs) selected plant were determined by micro-dilution method using clinical strains four species pathogenic...
Curcumin, a principal bioactive substance of turmeric (Curcuma longa L.), is reported as strong antioxidant, anti-inflammatory, antibacterial, antifungal, and antiviral agent. However, its antimicrobial properties require further detailed investigations into clinical multidrug-resistant (MDR) isolates. In this work, we tested curcumin's efficacy against over 100 strains pathogens belonging to 19 species. This activity was determined by the broth microdilution method calculating minimum...
Fucoxanthin is a carotenoid produced by brown algae and diatoms. This compound has several biological properties such as antioxidant, anti-obesity, anti-diabetic, anticancer, antimicrobial activities. Unfortunately, until now the latter effect been poorly confirmed. The aim of this study was an evaluation fucoxanthin activity against 20 bacterial species. Antimicrobial determined using agar disc-diffusion micro-dilution methods. studied acted 13 bacteria growing in aerobic conditions. It...
Flavonoid content was determined spectrophotometrically, and organic acid concentrations by HPLC.The of the studied compounds varied greatly.Interspecific differences in amount flavonoids ascorbic were highly significant.The most common species, Rosa canina, showed low average vitamin C (0.51 g/100 g dry matter) (41 mg/100 DM) high citric (3.48 DM).Ascorbic highest R. villosa hips (avg.2.25 DM), rubiginosa (72 tomentosa (4.34 DM).Flavonoid level correlated negatively with...
Oak acorns used to be an important human food, up until recent times.The major factor inhibiting their use in modern nutrition is high tannin content.Polish oak trees were screened order find out whether there are any geographical or interspecific differences and total phenolic contents acorns, which might help us establish further directions the search for low-tannin individuals.We studied level of compounds using standard Polish European Pharmacopoeia method, with Folin-Ciocalteu reagent...
Coltsfoot (<em>Tussilago farfara</em> L.) is a common species, widely used in European and Chinese traditional medicine for the treatment of respiratory diseases. However, raw material from this plant contains hepatotoxic pyrrolizidine alkaloids (PAs). The aim study was to determine variability level PAs (senkirkine senecionine) leaves coltsfoot originated natural populations Poland. In phytochemical analysis, 20 samples <em>T. were used. This obtained Garden Medicinal...
Summary Introduction: For centuries, mosses have been used in traditional medicine due to their antibacterial, antifungal, and antiviral activities. Objective: The present study was designed evaluate the antibacterial activity of ethanolic extracts obtained from 12 moss species: Brachythecium albicans, Bryum argenteum, Ceratodon purpureus, Dicranum scoparium, Dryptodon pulvinatus, Orthotrichum anomalum, Oxyrrhynchium hians, Plagiomnium undulatum, Polytrichum juniperinum, P. piliferum,...
Apigenin (4′,5,7-trihydroxyflavone) and luteolin (3′,4′,5,7-tetrahydroxyflavone) are among the most widely distributed flavone aglycones in flowering plants. These metabolites often occur form of O- C-glycosides. In this group, four C-glucosides pay special attention: vitexin (apigenin 8-C-glucoside) isovitexin 6-C-glucoside) as well orientin (luteolin isoorientin 6-C-glucoside). The above-mentioned compounds show various biological activities, including antioxidant, anti-inflammatory,...
Roseroot (<em>Rhodiola rosea</em> L.) belongs to important herbs in folk medicine of Scandinavia, Russia, Mongolia, and China. Its therapeutic usage is mainly associated with the adaptogenic properties this species. characterized by high morphological, phytochemical, genetic differentiation. The aim present work was determine biometric phytochemical co-variability taxon. Samples <em>Rh. were collected from 4-year-old experimental field cultivation established rhizome...
The aim of the study was to investigate effect baicalein or Scutellaria baicalensis root extract interaction with methyldopa in pregnant spontaneously hypertensive rats (SHR) at pharmacodynamic, molecular, and biochemical levels. rats, after confirming pregnancy, received (200 mg/kg/day, p.o.) (1000 p.o.), combination (400 mg/kg/day; for 14 consecutive days, 1 h before blood pressure heart rate measurements. In placenta from mothers giving birth their offspring, mRNA expression factors...
Summary Roseroot (Rhodiola rosea L.) is an adaptogenic plant, widely used in the traditional medicine of Scandinavia, Russia, China and Mongolia. The aim study was to determine biometric phytochemical co-variability this species under field cultivation western Poland (Plewiska near Poznań). plant material originated from four-year-old established twice by rhizome division autumn 2007 2008. In study, 46 individuals (23 plants 2011 2012) were used. analysis included measurements basic...
Abstract The purpose of the study was to evaluate Chamerion angustifolium (L.) Holub genotypes for preliminary selection and further breeding programs aimed at obtaining a suitable industrial form pharmaceutical applications. Clonally propagated plants representing 10 Ch. were regenerated under in vitro conditions, hardened planted field. Studies included an evaluation shoot proliferation, phytochemical assessment ex as well investigations intraspecies variability regarding four phenological...
The aim of this study was to determine fruit yield <i>Oxycoccus palustris</i> under the climatic and habitat conditions northern Wielkopolska (the Greater Poland region), depending on type occupied plant community. Total number weight as well average cranberry leaf size were determined 33 plots with an area 1 m<sup>2</sup>, located 7 peatlands. On areas, European produced crops from 9.2 up 242.0 g &#56256;&#56457;&#56256;&#56323;...
