Abstract

Geographic conditions (altitude, climate, and local flora) lead to significant differences in the chemical composition of propolis. Therefore, more research is needed for propolis in different geographical regions. So, the aim of this study was to evaluate the phenolic profile, total phenolic content, antioxidant, and antidiabetic properties of Pülümür propolis from Turkey. Methanol (MeOH), chloroform (CHCl3), and hexane extracts of propolis were analyzed. LC-ESI-MS/MS analysis of the extracts showed that the most abundant phenolic compound is caffeic acid in the MeOH extract (2943.12±11.12 μg phenolics/g extract), while on the other hand, CHCl3 extract had the highest total phenolic content (125.75±1.02 mg GAE/g extract). Antioxidant activity was measured using ABTS and DPPH assays, whereas CHCl3 extract (IC50=6.35±0.11 and 28.84±0.10 μg/mL, respectively) and MeOH extracts (IC50=5.04±0.07 and 28.80±0.09 μg/mL, respectively) showed relatively high antioxidant activity. The MeOH extract showed better antidiabetic activity than the standard compound, acarbose (IC50=0.544 and 0.805 mg/mL, respectively).
