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), DPPH•, and ABTS•+ activities (41.07±1.43 mg GAE/g extract; 1.86±0.01 mg QE/g extract; 16.23±0.68 mg TE/g extract; 56.88±0.43 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 presents the first identification of mullein bee pollen oil fatty acids and their antioxidant activities. Importantly, the choice of solvent was found to significantly influence substance extraction compared to the extraction method.

“…Phenolic substance amount in V. insulare extracts (µg/mL) It was reported in previous studies that Verbascum species contained apigenin, apigenin glucoside, luteolin and luteolin glucoside phenolics [8,9,23]. In addition, in Verbascum species, the caffeic acid, rosmarinic acid, quercetin, apigenin, p-coumaric and protocatechuic acid (3,4-dihydroxybenzoic acid) presence were detected with by HPLC [16,27].…”

In the present study, 17 different phenolic contents of Verbascum insulare Boiss. & Heldr. ethanolic leaf (LEtOH), aqueous leaf pure (LPW), ethanolic root (REtOH) and aqueous root pure (RPW) extracts were determined by HPLC. Moreover, their antimicrobial, antioxidant and DNA protective activities were identified. Curcumin and salicylic acid were not detected in V. insulare LPW extract, whereas vanillin was not found in RPW extract. The gallic acid and 3,4-dihydroxybenzoic acid presence were not determined in any extract. Based on the results of the biological activity, it was found that the ethanolic extract showed a higher antioxidant and antifungal activity compared to pure aqueous extract and increased the DNA stability. As a result, it may be argued that the biological activity of the ethanolic extract is higher due to the total phenolics compared with the aqueous extract. Since no previous studies were available on the biological activities of this plant, the data obtained in the present study will contribute to future pharmacological studies. Rezumat În studiul prezentat, au fost studiate 4 extracte diferite ale speciei Verbascum insulare Boiss. & Heldr. prin HPLC, pentru a determina conținutul total al fenolilor din extractul etanolic din frunze (LEtOH), extractul apos din frunze (LPW), extractul etanolic din rădăcini (REtOH) și extractul apos din rădăcini (RPW). S-au determinat, de asemenea, activitățile antimicrobiană, antioxidantă și de protecție a structurii ADN-ului. Curcumina și acidul salicilic nu au fost evidențiate în extractul apos de frunze, iar vanilina nu a fost detectată în extractul apos din rădăcini. Acidul galic și acidul 3,4dihidroxibenzoic nu au fost puși în evidență în nici un extract. Ținând cont de rezultatele obținute privind activitatea biologică, s-a concluzionat că extractul etanolic prezintă o activitate antioxidantă și antifungică mai puternică comparativ cu extractul apos, determinând și creșterea stabilității structurii ADN-ului. Se poate afirma, în concluzie, că activitatea biologică a extractului etanolic este superioară datorită cantității totale de fenoli, compativ cu extractul apos. Deoarece nu există studii anterioare privind activitățile biologice ale acestei plante, datele obținute în cadrul prezentei cercetări vor contribui la viitoarele studii farmacologice.
