The aim of this study was to investigate the effect blackberry and raspberry fruits (1 4%) leaves (0.5 1%) on biological activities rape honey. Honey plant material extracts were analyzed regarding total phenolic, flavonoid, anthocyanin contents, HPTLC HPLC polyphenol profiles, as well antioxidant activity. antiviral potential against bacteriophage phi 6-a coronavirus surrogate-whereas antimicrobial tested S. aureus E. coli. Blackberry more abundant in antioxidants than extracts, with better...
Rape honey with the addition of Aronia melanocarpa dried fruits is a new product, enriched additional bioactive compounds, increased antioxidant potential and enhanced antibacterial antiviral activity.
Nine samples of ethanolic extracts poplar-type propolis (EEP) originated from South-Eastern Poland were analyzed in terms the diversity flora around apiary. The mineral composition, antioxidant properties, polyphenolic profile (HPTLC), and main constituents (HPLC-DAD) determined. Only minor differences chemical composition capacity between tested EEPs found regardless their botanical origin. However, biological activity was more diversified. showed stronger antibacterial against...
The aim of the study is to evaluate effect addition selected fruits and herbs belonging "superfoods" category for bioactivity a rapeseed honey matrix. Flavored creamed honeys with nine types various additives (2 4% content) were prepared analyzed content total phenols, flavonoids, antioxidant (FRAP, DPPH ABTS) antibacterial activity against four strains bacteria. Additionally, impact three months storage on properties products obtained was examined. significant dose-dependent increase in...
Two various species of mulberry (Morus sp.) were selected to enrich rape honey with dried leaves or lyophilized fruits (4% w/v). Finally, and the 'Ukraińska' clone introduced into during creaming in concentrations from 1 4% w/v. The total phenolic content, antioxidant activity, anthocyanins polyphenolic profile tested plant extracts enriched honeys. Moreover, α-glucosidase, β-galactosidase, diastase activities investigated For extracts, chlorogenic acid isomers rutin considered main...
Fir honeydew honey is a uniquely beneficial product which often subjected to adulteration; however, pollen analysis not useful verify this type. Fourteen samples of EU protected designation origin fir gathered directly from apiaries were studied. Standards legal requirements and additional parameters, i.e., specific optical rotation, mineral content, antioxidant activity, tested. Five nectar honeys different varieties used as comparative material. HPTLC SDS-PAGE methods fingerprint the...
Drone brood is a little-known bee product which frequently considered as male equivalent of royal jelly and sometimes used its adulterant. The aim the study was to compare chemical composition biological activity both products originated from same apiaries (n = 3) limiting influence genetic environmental factors. Moreover, for drone covered testing three stages larval development (days 7, 11, 14). comparison included mineral (ICP-OES method), protein content profile (SDS-PAGE), testosterone...
Plants from Asteraceae family are widely used for their therapeutic effects in the treatment of gastrointestinal diseases, but consequences excessive intake still need to be studied. The aims this study were evaluation cytotoxicity, measurement antioxidant properties and determination polyphenolic profile Tanacetum vulgare L. (tansy), Achillea millefolium (yarrow) Solidago gigantea Ait. (goldenrod) ethanolic extracts. cytotoxicity extracts was monitored by xCELLigence system real time using...
Drone brood is a little-known and poorly studied bee product used valued in the treatment of many diseases, including male infertility women’s menopausal disorders. The aim this study was to evaluate antioxidant activity drone depending on stage larval development method preservation. Aqueous ethanolic homogenate extracts were assayed for (with DPPH, FRAP, ABTS methods), polyphenol, flavonoid content. extracts’ polyphenolic profiles compared by HPTLC method. has been shown be more active...
The aim of the research was to assess impact liquefying honey by ultrasound processing on its biological activity. Four solid samples different botanical origin were decrystallized using (sonic bath, 40 kHz, 800 W) and conventional thermal (water °C). properties liquefied control honeys compared. significantly shortened time liquefaction (from 24 h 15 min) delayed re-crystallization process compared method 1 4 months). Diastase number comparable in unprocessed honeys, but decreased...
The aim of the study was to use protein and polyphenolic profiles as fingerprints goldenrod honey apply them for verification labeled variety. markers 10 samples were correlated with standard physicochemical parameters biological activity measured in vitro antioxidant, antifungal antibacterial activities. Honey proteins examined regarding soluble protein, diastase SDS-PAGE profile. profile obtained HPTLC antioxidant detected colorimetric methods. antimicrobial effect representative different...
Drone brood is a little-known bee product, often treated as beekeeping waste or natural varroosis bait. Obtaining drone from beehives does not weaken the family, which why this product used medicine in Eastern European countries. The main objective of work was to design an innovative dietary supplement containing freeze-dried (DB) enriched with calcium ions (3:1). As component, inorganic carbonate (CC) and ground chicken eggshells (ES) were used. Bioaccessibility hormones, selected nutrients...
Bee bread is a valuable product obtained from the hive on relatively small scale, while bee pollen more easily available. Therefore, an effective laboratory method of converting into substitute desired. The aim research was to verify influence selected factors (temperature, ultrasound) quality using Lactobacillus rhamnosus inoculum. composition fermented analyzed Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), Raman spectroscopy, and SDS-PAGE compared natural original...
Abstract Proteins and amino acids are minor components of honey that rarely used for its quality evaluation, although these create biological activity as well can serve overheating detection. The aim the study was to use indicators confirm a declared on label variety. Fifty-eight samples 8 different varieties meeting commercial requirements were used, including 28 local Polish 30 (mainly imported from EU non-EU) honeys. For protein profiling previously polyacrylamide electrophoresis in...
Abstract Bee drone brood is a beehive by-product with high hormonal activity used in natural medicine to treat male infertility. The aim of the study was assess effect on stallion spermatozoa during short-term incubation for its potential use equine semen extenders. Three different forms fixed (frozen (FR), freeze-dried (FD), and dried extract (DE)) were used. Solutions compared terms testosterone, protein, total phenolic content, antioxidant activity. diluted prepared solutions....
The growing phenomenon of honey adulteration prompts the search for simple methods to confirm authenticity honey. aim study was evaluate changes in thermal characteristics, physicochemical parameters, antioxidant and enzymatic activity subjected artificial adulteration. Two series products were prepared with use two different sugar syrups an increasing dosage adulterant (0 30%). After 24 months storage, quality adulterated samples (partially crystallized) assessed comparison control (solid)....
The aim of the study was to compare nutritional value and bioactivity honey enriched with a 10% addition natural bee bread its substitutes obtained as result laboratory fermentation pollen. Physicochemical parameters, antioxidant properties, well bioaccessibility proteins using an in vitro static digestion model were analyzed. honeys tested yeast model. research indicates similarity “artificial bread” ones. During digestion, good protein from products demonstrated. ability protect cells...
Abstract Crystallization of honey is a natural process occurring during storage and forces beekeepers to practice the decrystallization process, which mainly concerns heating. The aim this study was examine possible use ultrasounds or microwave radiation delay crystallization liquefy crystallized honeys while maintaining their biological activity.
