This study aimed to determine the standard amount of antioxidant content and compounds propolis for standardization propolis. For this purpose, total flavonoids, phenolic, CUPRAC capacity diversity phenolic flavonoid components these samples were found by HPLC determined at 23 which collected different regions Turkey. Beside that, similarities differences provinces each other according their capacities investigated multidimensional scaling analysis. The in between 21.28 152.56 mg CE/g. was...

Abstract Honeybee venom (HBV) is an important product of beehives, and its benefits for health have been rediscovered by modern medicine. Since HBV has the potential to treat some diseases, quality production conditions require a detailed investigation. The objective this study understand how season, harvesting time (day or night), site beehives (inside entrance) geographic location affects through analysis apamin, melittin phospholipase A 2 (PLA2) content. Each set six colonies were used...

Abstract Bee bread is a bee product produced by bees in which they combine pollen with their digestive enzymes and place them the comb cells. In this study, it was aimed to evaluate nutritional antioxidant properties of Anatolian present an examination regional differences. order emphasize bioavailability determine its phenolic, flavonoid content, activity quality, ten samples were collected from different parts Anatolia. Seven Muğla (prominent city terms honey production), one Van...

The purpose of this research was to identify the biological activity Turkish pine honeys and most abundant phenolic compound(s) guide future studies be done about type honey. Moreover, will provide chance introduce by elucidating a distinct parameter compared other forms honey reported in literature. To end, microscopic examination based on number honeydew elements (NHE) total pollen (NTP) grains performed 17 samples from Aegean region Turkey. Then 18 commonly-occurring standards were used...

This study analysed some physicochemical and quality parameters of 176 royal jelly (RJ) samples from different regions Türkiye, collected over years seasons. According to the obtained results, moisture percentage varied between 47.36 % 69.58 %, with no statistically significant differences seen across various seasons areas (p>0.05). The average value 10-hydroxy-2-decenoic acid (10-HDA), which varies according factors such as season, region, year, was determined be 2.32 %. It also that this...

This study aims to discover the characteristic chemical factors for determining region of royal jelly using machine learning. 84 samples from 13 different regions Turkey were used study, and parameters moisture, pH, acidity, 10-hydroxy-2-decanoic acid (10-HDA) investigated. ANOVA test was conducted determine whether there are differences between locations concerning four values. In addition statistical tests, a learning model find out what makes each other. The descriptive statistics...
