Journal of Food Measurement and Characterization 14(4), 1795–1809 (2020) Sorkun, Bee bread and bee pollen of different plant sources: determination of phenolic content, antioxidant activity, fatty acid and element profiles. ![]() Silici, Bilimsel Gerçeklerle Apiterapi, Akademisyen Kitapevi, Türkiye, 2020 Moreover, the significant presence of Mg, P, Fe and Ca, high K/Na ratio, vitamin C, B2, B5 and B6 content makes bee pollen collected from Rhododendron ponticum plant attractive for diets. However, the presence of phenolic compounds (myricetin, epicatechin, tyrosol etc.) and amino acids (L-asparagine, gamma-aminobutyric acid, L- Tryptophan etc.) with significant biological activity indicates that this product is a bee product with high medicinal properties. As a result of analysis with LC-MS-MS, it was found that it contains L-asparagine and myricetin in a significantly higher concentration compared to other amino acids and phenolic compounds. In addition, it was characterized by a low content of vitamin A (retinol), B7, B12, K2, as well as a deficiency of vitamin K1. ![]() The total individual phenolic compound content of Rhododendron ponticum bee pollen was determined as 11928.23 µg/100 g, total element content as 13997.75 mg/kg, total free amino acid content as 149466.11 µg/g and total vitamin content as 20509.37 µg/100 g. Then, the chemical profile of Rhododenron ponticum bee pollen was examined in terms of 31 elements, 42 amino acids, 33 phenolics and vitamins A, B1, B2, B5, B6, B7, B12, C, E, K1 and K2. In the first stage, the botanical origin of the sample was confirmed by palynological analysis supported by light microscopic images. In this study, it was aimed to characterize the pollen collected by bees from the Rhododenron ponticum plant, which is the source of mad honey, in terms of some parameters.
