Comprehensive Study of the Physicochemical Properties of Royal Jelly from Various Regions of Türkiye.

This study analysed some physicochemical and quality parameters of 176 royal jelly (RJ) samples from different regions of Türkiye, collected over different years and seasons. According to the obtained results, the moisture percentage varied between 47.36 % and 69.

Identification of the Main Phenolic Markers in Turkish Pine Honeys and Their Biological Functions.

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

Determination of antioxidant activity and phenolic compounds for basic standardization of Turkish propolis.

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