ABSTRACT
This study focused on characterizing fatty acids and evaluating the antioxidant properties in oils extracted from mullein (Verbascum sp.) bee-collected pollen, utilizing soxhlet and ultrasound-assisted methods with acetone and hexane solvents. Soxhlet extraction demonstrated high efficiency in mullein bee pollen oil extraction. The highest levels of total phenolic content (TPC), total flavonoid content (TFC), DPPHâ
, and ABTSâ
+ activities (41.07±1.43â
mg GAE/g extract; 1.86±0.01â
mg QE/g extract; 16.23±0.68â
mg TE/g extract; 56.88±0.43â
mg TE/g extract, respectively) were observed in oil extracted using the soxhlet method with acetone solvent. Conversely, ultrasound-assisted extraction with hexane yielded oils rich in saturated fatty acids, while acetone extraction contained higher monounsaturated fatty acids. Palmitic, linoleic, and oleic acids were predominant in the extracted oils. This study introduces, for the first time, the identification of fatty acids found in mullein bee pollen oil, along with an examination of their antioxidant properties. The choice of solvent was found to significantly influence compound extraction compared to the extraction method.
