Spectrophotometric Analysis of Flavonoid Quantity in Pollen of Amygdalus communis L. and Determination of Biomarkers
Öz
In this study, the amount of flavonoid aggregates in the pollen of the common almond (Amygdalus communis L.) plant, which is common in Nakhchivan MR, was analyzed. The study of flavonoids in pollen can provide useful information for assessing the nutritional and healing quality of bee products. In the study, an extract was prepared on 60% ethyl alcohol from the pollen of the common almond plant. For the determination of flavonoids, a solution of 2% aluminum chloride in alcohol and a standard rutin solution were used. Biochemical analysis was performed by spectrophotometer method. The determination of flavonoid concentration was determined by measuring their absorbance at a wavelength of 310 nm. Based on the absorption results of solutions of different concentrations of rutin, the dependence in the calibration graph is expressed by the equation Y=0.032x+0.477. The correlation coefficient was R=0.993. The optical density (Y) of common almond (A. communis L.) pollen extract in alcohol was calculated based on the equation given in the calibration graph and was determined to be 0.041±0.02 mg/mL flavonoid (according to rutin). As a result of spectrophotometric research, it was determined that the pollen of common almond (A. communis L.) contains 10.29±1.16% flavonoid aggregate.
