With everyday advances in the field of pharmaceuticals, medicinal plants have high priority regarding the introduction of novel synthetic compounds by the usage of environmentally friendly extraction technologies. Herein, a supercritical CO2 extraction method was implemented in the analysis of four plants (chamomile, St. John’s wort, yarrow, and curry plant) after which the non-targeted analysis of the chemical composition, phenolic content, and antioxidant activity was evaluated. The extraction yield was the highest for the chamomile (5%), while moderate yields were obtained for the other three plants. The chemical composition analyzed by gas chromatography-high-resolution mass spectrometry (GC-HRMS) and liquid chromatography-high-resolution mass spectrometry (LC-HRMS) demonstrated extraction of diverse compounds including terpenes and terpenoids, fatty acids, flavonoids and coumarins, functionalized phytosterols, and polyphenols. Voltammetry of microfilm immobilized on a glassy carbon electrode using square-wave voltammetry (SWV) was applied in the analysis of extracts. It was found that antioxidant activity obtained by SWV correlates well to 1,1-diphenyl-2-picrylhidrazine (DPPH) radical assay (R2 = 0.818) and ferric reducing antioxidant power (FRAP) assay (R2 = 0.640), but not to the total phenolic content (R2 = 0.092). Effective results were obtained in terms of activity showing the potential usage of supercritical CO2 extraction to acquire bioactive compounds of interest.

Culinary spices and herbs have been used in food and beverages to enhance aroma, flavor, and color.  They are rich in phytochemicals that provide significant antioxidant and anti-inflammatory effects. There is growing interest in identifying compounds from spices and herbs responsible for modulating oxidative and inflammatory stress to prevent diet-related diseases.  This contribution will provide an overview of culinary spices and herbs, their classification, their sources or origins and more importantly, their chemical composition, antioxidant activity and their impacts on human health based on important and recent studies.

Objectives: Traditional healers (THs) from the Central and Kara regions of Togo use Aframomum melegueta(Alligator pipper), Khaya senegalensis (Senegal mahogany) and Xylopia aethiopica (Kani pepper) for the treatment of helminths infections. We previously confirmed the anthelmintic effects of these plants. THs had little information about plants compounds, anti-inflammatory, antioxidant activities and toxicity. The present study aimed to investigate antiinflammatory, antioxidant activities and toxicity of Aframomum melegueta, Khaya senegalensis and Xylopia aethiopica used for the treatment of helminthiasis in the Central and Kara regions of Togo. Methodology and Results: Anti-inflammatory activity was evaluated using the inhibition method of lipoxygenase type IB extracted from soybean. The concentrations of polyphenols and flavonoids were measured respectively by the FolinCiocalteu reagent reduction method and the Aluminium chloride colorimetric method. Antioxidant activity was assessed by the DPPH and ABTS assays. Acute and subchronic toxicity was performed on Wistar rats according to OECD recommendations. Khaya senegalensis and Xylopia aethiopica showed, a greater anti-inflammatory activity by inhibiting lipoxygenase activity in vitro and antioxidant activity (Aframomum melegueta; ABTS 32.79±3.79 mgEAA/100mg and Xylopia aethiopica; DPPH IC50 of 2278.89±104.68 µg/mL). Khaya senegalensis contained a high concentration of flavonoids (1.39±0.07 mgEQ/100mg) and phenols (329.21±19.99 mgEGA /100mg). No toxic effects were observed for the chosen doses with these plants extract. Conclusions and application of findings: Extracts of Khaya senegalensis and Xylopia aethiopica had anti-inflammatory activities. In addition, extracts of Khaya senegalensis and Aframomum meleguetahad excellent antioxidant power and had the highest concentrations of polyphenols and flavonoids. This finding could justify the traditional use of these plant Ataba et al., J. Appl.
