“…In vitro antioxidant activity of the WBE microcapsules with different wall compounding ratios was determined by hydroxyl radical (Wang et al ., 2020), ABTS radical (Lin et al ., 2022), DPPH radical (Gong et al ., 2018) scavenging rate and reducing power (Allane & Benamara, 2019), and calculated according to eqn (1).

P (%) = (1 - (A_{i} - A_{j}) / A_{0}) \times 100

where A i is the absorbance value of sample solution, A j is the absorbance value of the blank control (distilled water), and A 0 is the absorbance value of the sample control.…”

Wheat bran extracts (WBE, mainly composed of feruloyl oligosaccharides (FOs)) have been approved by FDA in GRAS Notice. WBE was utilised in octenyl succinate anhydride-modified starch (OSA-starch)based microcapsules as wall materials to protect β-carotene (BC) from oxygen. The storage retention and antioxidant indexes in vivo and in vitro of microcapsules were determined. The results showed that these characteristics were positively related to the proportion of WBE in the wall material. The in vivo antioxidant indexes in mouse serum and liver were positively regulated at gavage dose around content in wheat grain (normal dose), while at a higher dosage, the in vivo free oxidative stress fell into disorder. The results indicated that WBE was a good component of wall material, which can improve the antioxidant environment during both storage and consumption. This experiment provides a theoretical basis for the industrial application of WBE in the field of microcapsules.

“…In fact, there is a growing demand to produce novel functional foods with significant health benefits. The use of plant extracts as natural preservatives for various vegetable oils has been extensively researched (Allane and Benamara, 2019). In this respect, wormwood is a promising medicinal plant due to its richness in a large variety of secondary metabolites such as saponins, tannins, alkaloids, sterols, triterpenoids, phenolic, flavonoids and glycosides, exhibits biological activities (Dahal et al, 2021).…”

In fact, the powerful antioxidant, antimicrobial, anti-inflammatory and anti-diabetic properties of wormwood are due to its high content in lipophilic antioxidant molecules (Allane and Benamara, 2019). Nowadays, literature reports that Artemisia extracts and Covid-Organics exhibit some anti-viral activity against SARS-CoV-2 in vitro (Nie et al, 2021).…”

Olive oil is the most popular product derived from Olea europaea L. due to its organoleptic characteristics and its beneficial effects on human health. Nowadays, there is a growing interest in olive oil enrichment with medicinal plants. In this regard, Artemisia absinthium L. is an edible source of antioxidants. The aim of the present study was to improve the oxidative stability and the nutritional value of Organic Tunisian Chetoui Olive oil by its enrichment with the phenolic compounds in Artemisia absinthium. The enrichment carried out by maceration and ultrasound-assisted extraction did not affect the organic criteria of olive oil. The comparative study, performed during one year of storage, showed that ultrasound-assisted extraction led to the lowest final peroxide and extinction coefficient values. At the end of storage, this method increased oleic acid content and biophenol contents. Furthermore, the anti-radical activities of enriched samples were higher than the control.

Growing concern for public health has increased the need to change the paradigm towards a healthcare system that advocates holistic practices while reducing adverse effects. Herbal therapy is becoming an integral part of the therapeutic arsenal, and several successful plant-derived compounds/molecules are being introduced into the market. The medicinal plants belonging to the genus Thymus are among the most important species within the Lamiaceae family. One of them is Thymus algeriensis which is mainly distributed in the Mediterranean region. For a long time, this species has been used in traditional medicine to treat several disorders and diseases including inflammation, diabetes, rheumatism, digestive, and respiratory affections. This review describes the traditional uses, phytochemical composition, and biological and pharmacological activities of T. algeriensis extracts. Data were obtained using electronic databases such as SciFindern, ScienceDirect, Scopus, and Web of Science. Several plant-based extracts and a broad spectrum of identified secondary metabolites were highlighted and discussed with respective activities and modes of action. T. algeriensis represents a promising natural resource for the pharmaceutical industry mainly for antioxidant, anti-inflammatory, antimicrobial, and anticancer activities. Considering these findings, more research is needed to transmute the conventional uses of T. algeriensis into scientifically sound information. Moreover, extensive preclinical, clinical, toxicological, and pharmacokinetic trials on this species and its derivatives compounds are required to underpin the mechanisms of action and ensure its biosafety and efficiency. This comprehensive review provides a scientific basis for future investigations on the use of T. algeriensis and derived compounds in health maintenance and promotion and disease prevention.
