In this study, the botanical origin, total flavonoid and phenolic content, antioxidant activity, profile fatty acid composition of mixed bee pollen loads collected in Bayburt, Turkey, were determined. addition to these assays, antibacterial activity bee-collected extract (BCPE) against a variety food-borne pathogenic bacteria was determined vitro. Pollen classified into five families based on their color: Asteraceae, Fabaceae, Campanulaceae, Cistaceae Rosaceae. Total flavonoid, phenolic,...
In this study, chestnut honey-based silver nanoparticles (CH-AgNPs) were synthesized at different temperatures (30, 60 and 90 °C) these characterized by techniques such as UV–vis spectrophotometer, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) energy dispersive X-ray (EDX). The DPPH free radical scavenging assay was used to determine the antioxidant activity of obtained nanoparticles. inhibition effects for some clinically important enzymes...
In recent years, there has been increasing interest in green extraction methods and solvents due to their many advantages. this study, the effects of an ultrasonic method deep eutectic (DESs) on different bioactive substances from bee pollen were investigated. regard, process variables such as molar ratio DES (1, 1.5, 2), sonication time (15, 30, 45 min), power (90, 135 180 W) total individual amino acids, organic phenolic compounds investigated by response surface methodology (RSM). The...
Determination of the protective property melanin, an organic polymer class consisting phenolic and/or indolic compounds isolated from bacteria and fungi, against fast neutron radiation. To show that these melanin samples, which also have antioxidant metal chelating properties, can be used as active ingredient for a drug to developed neutrons in nuclear research medicine.Bacterial fungal media were prepared, pigments produced isolated. For molecular characterization pigments, bacterial...
Abstract Natural colorants have become a developing market because of consumer preferences, and more cost-effective stable production is necessary. In the present study, natural green colorant was obtained via microwave-assisted extraction from spinach waste to produce affordable, environmentally-friendly, innovative colorants. The extracts were encapsulated with zein uniaxial coaxial electrospinning techniques overcome stability issues associated their color. encapsulation efficiencies...
AbstractBy-products with remarkable bioactive properties are formed in extraction processes of essential oils from plant materials. In present study, it was aimed to determine the concentration individual phenolic and organic acid compounds by LC-MS/MS by-product (wastewater) collected after oil isolation Pelargonium graveolens L. some this by-product. addition, chemical analysis antibacterial activity extracted P. were determined histo-anatomical characterization glandular trichomes leaf...
Royal jelly is one of the most remarkable commercial bee products used in cosmetics, medicine, and as a dietary supplement. This study aimed to determine some quality parameters (amino acid, multi-elemental, total phenolic-flavonoid, 10-HDA, sugar, moisture content) well antioxidant antimicrobial activities different royal samples (domestic non-domestic samples). In this study, exhibited high activity. 10-HDA values were found be higher domestic (2.17–2.71%) compared (0.31–1.71%). Also, it...
This study was performed to investigate the antimicrobial effect of propolis from Hakkari province Turkey and its chemical content by Gas Chromatography–Mass Spectroscopy. In vitro inhibitory activity studied disc diffusion method against six gram positive, three negative bacteria one yeast like fungi. As a result analysis, total flavonoid ratio sample found be higher than other compound groups. Pinostrobin chalcone, pinocembrin chrysin were identified as major flavonoids. Also, all...
This study aimed to determine the volatile profile by GC-MS and antimicrobial activity of essential oil isolated from Thymus nummularius using microwave-assisted hydrodistillation method morphologically characterize glandular trichomes in leaf samples. Obtained oil, as well wastewater obtained during isolation, were chemically (polyphenolic compounds, organic acids, total phenolic content, flavonoid content antioxidant activity) characterized. As a result analysis different ratios components...
The aim of this study was to determine the plant sources, physicochemical properties, element content and antimicrobial effects honey samples collected from 10 different regions province Bayburt, Turkey. melissopalynological analyses showed that pollen 67 taxa belonging 34 families in were found rates TPS-10 value between 16024-90126. In addition these, amount ash 0.13% -0.32%, electrical conductivity 0.36-0.69 mS/cm, moisture 16.1% 18.9% fructose/glucose ratio 0.92-1.18. As a result...
In this study, it was aimed to examine the capacity of deep eutectic solvents (DESs) with different contents extract bioactive compounds from tarragon (Artemisia dracunculus L.) plant. For reason, total phenolic-flavonoid content, proanthocyanidin content and antioxidant/antimicrobial activities prepared DES extracts were investigated, as well individual phenolic amino acid profiles. According results, DES10 had highest efficiency in terms its phenolics (approximately 59 mg/100 g) acids 2500...
