Résumé

The discovery, progress, and marketing of nutraceuticals and related products are rapidly expanding segments of the food industry that are overtaking the conventional processed food market. The present study investigates the antioxidant, anti-inflammatory, and cellular viability assessment of fennel essential oil. The selection of the extraction process and geographical distribution of fennel play a key role in determining the final composition and hence the corresponding activity of the bio-actives. During the current project, fennel from two origins (Egypt and Pakistan) was procured and subjected to extraction by two methods, i.e., conventional Soxhlet extraction and supercritical fluid extraction, by changing solvent, time, and pressure correspondingly. The resultant extracts were subjected to various analyses, including yield, determination of total phenolic content, and various antioxidant assays. The highest total phenolic content (TPC) was obtained with supercritical fluid extract (206 bar) for Egyptian (180.65±1.22 mg GAE/g) and Pakistani fennel (372.66±0.15 mg GAE/g). The highest values for antioxidant assays were obtained for fennel of Pakistani origin prepared with supercritical fluid extract at 206 bar such as 32.65±0.1 µmole Trolox equivalent/g for FRAP, 74.5% inhibition for ABTS and 126.25±1.48 µM Trolox equivalent/mL for ORAC. This data obtained suggested that amongst extraction techniques employed, supercritical fluid outstands conventional extraction and essential oil of Pakistani fennel depicted better yield, antioxidant potential, cellular viability, and anti-inflammatory assay than others. The present study paves the way to outline and investigate different factors governing variation in essential oil profiles in response to geographical distribution.
