Honey has been considered to have therapeutic properties since ancient times and among the factors responsible for such activity are phenolic compounds including acids flavonoids from different natural sources.This study investigated profile bioactive of honey types Romanian flora in order develop reliable tools floral origin, thus contributing traceability European Union context.Thirty-three samples were examined, unifloral (acacia rape), polyfloral, honeydew honeys mixture honeys. Phenolic...
Abstract Propolis, a complex bee product, is source of numerous bioactive principles, beneficial for human health, therefore it intensively studied. In the present work, extracts propolis from Bihor Romanian County were studied to identify relationship between polyphenolic derivatives profile and their antioxidant antimicrobial activity. Extracts obtained using water 25%, 50%, 70% ethanolic solutions (w/w), at 2:1, 4:1, 6:1 liquid: solid ratios (w/w). 21 quantified by UHPLC-MS, proving that...
One of the most important issues in wine sector and prevention adulterations wines are discrimination grape varieties, geographical origin wine, year vintage. In this experimental research study, UV-Vis FT-IR spectroscopic screening analytical approaches together with chemometric pattern recognition techniques were applied compared addressing two authentication problems: (i) varietal (ii) vintage red produced same oenological region. spectra registered for all samples principal features...
Phenolic compounds are plants’ bioactive metabolites that have been studied for their ability to confer extensive benefits human health. As currently there is an increased interest in natural identification and characterization, new analytical methods based on advanced technologies developed. This paper summarizes current advances the state of art polyphenols quantification. Analytical techniques ranging from high-pressure liquid chromatography hyphenated spectrometric discussed. The topic...
This paper evaluated the chemical and biological properties of bee pollen samples from Romania. Firstly, alcoholic extracts (BPEs) were obtained raw harvested by Apis mellifera carpatica bees. The composition BPE was determination total phenol content flavonoid content, UHPLC-DAD-ESI/MS analysis phenolic compounds, GC-MS fatty acids, esters, terpenes. Additionally, antioxidant activity Trolox Equivalent Antioxidant Capacity method. Furthermore, (antimicrobial cytotoxic activity). BP studied...
Grapes are rich in phenolic compounds, being important for human health with anti-inflammatory, antiatherosclerotic, antimutagenic, anticarcinogenic, antibacterial, antiviral, and antimicrobial activity. The winemaking of the grapes generates significant amounts waste. These wastes contain bioactive compounds their biomass that can be used as a source food improvement or nutrition supplementation. This study looks at content polyphenolic profile, antioxidant activity different white red...
Bee bread has received attention due to its high nutritional value, especially phenolic composition, which enhances life quality. The present study aimed evaluate the chemical and antimicrobial properties of bee (BB) samples from Romania. Initially, alcoholic extracts (BBEs) were obtained BB collected prepared by Apis mellifera carpatica bees. composition BBE was characterized Fourier Transform Infrared Spectroscopy (FTIR) total phenols flavonoid contents determined. Also, a UHPLC-DAD-ESI/MS...
The producers of essential oils from the Republic Moldova care about quality their products and at same time, try to capitalize on waste processing. purpose present study was analyze chemical composition lavender (Lavanda angustifolia L.) oil some by-products derived its production (residual water, residual herbs), as well assess “in vitro” antimicrobial activity. gas chromatography-mass spectrometry analysis produced by seven industrial manufacturers led identification 41 constituents that...
Chestnut (Castanea sativa Mill.), a valuable fruit crop, is cultivated in small areas Romania, mostly the west, where moderate continental climate has slight Mediterranean influence. This work aims to investigate bioactive characteristics (total polyphenols, total flavonoids and antioxidant activity), individual polyphenolic composition, phytochemical nutritional HRMS screening profiles, sugar mineral composition of six sweet chestnut cultivars, namely ‘Marsol’, ‘Maraval’, ‘Bournette’,...
Interest in the extraction of phytochemical bioactive compounds, especially polyphenols from biomass, has recently increased due to their valuable biological potential as natural sources antioxidants, which could be used a wide range applications, foods and pharmaceuticals green polymers bio-based materials. The present research study aimed provide comprehensive chemical characterization composition forest biomass (bark needles) softwood species (Picea abies L., H. Karst., Abies alba Mill.)...
Identification and quantification of polyphenols in plant material are great interest since they make a significant contribution to its total bioactivity. In the present study, an UPLC-Orbitrap-MS/MS approach using variable data acquisition mode (vDIA) was developed applied for rapid separation, identification, main polyphenolic compounds Medicago sativa L. Trifolium pratense sprouts different germination stages. Based on accurate MS fragment ions identification strategy, 29 were identified...
To the best of our knowledge, this is first study demonstrating efficiency Allium sativum hydro-alcoholic extract (ASE) againstFigure growth, biofilm development, and soluble factor production more than 200 biodeteriogenic microbial strains isolated from cultural heritage objects buildings. The plant composition antioxidant activities were determined spectrophotometrically by HPLC-MS. bioevaluation consisted qualitative (adapted diffusion method) quantitative evaluation inhibitory effect on...
Extra-virgin olive oil (EVOO) and virgin (VOO) are valuable natural products of great economic interest for their producing countries, therefore, it is necessary to establish methods capable proving the authenticity these oils on market. This work presents a methodology discrimination extra-virgin from other vegetable based targeted untargeted high-resolution mass spectrometry (HRMS) profiling phenolic triterpenic compounds coupled with multivariate statistical analysis data. Some (cinnamic...
This study presents a novel methodology for the rapid on-site detection of tannic acid (TA), prevalent organic contaminant in various natural environments, notably plant-derived sources. The proposed approach involves development compact integrated electrochemical sensor incorporating nanozyme system. Specifically, this system comprises Fe2O3 nanoparticles (NPs) embedded within chitosan (CS) matrix, immobilized onto sulfur-doped graphene (S-Gr) substrate deposited on gold electrode (AuE)....
