“…The uses of synthetic antioxidants in food products were restricted owing to their instability and to their suspected action as carcinogenesis promoters (Namiki, ). Therefore, there has been an increasing tendency via the usage of natural alternative sources generally present in plants (Beddou, Bekhechi, Ksouri, Sari, & Atik Bekkara, ). Essential oils and phenolic compounds, extracted from many plants, have recently gained popularity and scientific interest as natural preservatives in food industry.…”

This study was designed to examine the effect of provenance on the phytochemical and antioxidant properties of essential oil and methanolic extract from Tunisian and French fennel seeds (FFS). Analysis of the essential oil showed that although the same main compounds were found in Tunisian and FFS cultivars, some differences were present in their proportions allowing to classify them in two chemotypes. The first class was composed by trans‐anethole (63.41%–78.26%) for Tunisian cultivars and the second one by estragole (44.72%–88.92%) for French cultivars. The phenolic composition of all fennel seed extracts was characterized by its richness in quinic acid, 4‐O‐caffeoylquinic acid, p‐coumaric acid, and 4‐O‐caffeoylquinic acid. All fennel seed extracts showed a better antioxidant potential than their essential oils depending on the origin. Principal component analysis showed a dispersion of the cultivars on three groups depending on the chemotype diversity. Practical applications Recently, much attention has been focused on fennel due to the nutritional and health‐protective value of their seeds. Several studies have highlighted the importance of fennel seed extracts and essential oils as key ingredients rich in bioactive compounds serving in formulation of new functional food products. This investigation designed to examine the effect of provenance on phytochemical and antioxidant potentials of Tunisian and French fennel seed extracts and essential oils.

“…The treatment with the highest reducing power was the solution of 10 mg/mL of water extract with an absorbance value of 0.55. Furthermore, many studies performed with different plant species such as Eruca sativa [Sarwar Alam et al 2007], Rumex vesicarius [Beddou et al 2015], Artemisia annua [Wan et al 2016] and Momordica charantia [Svobodova et al 2017] in previous years revealed that reducing power activity increased in concentration-dependent manner.…”

Ceratophyllum demersum L. is a medical plant of the family Ceratophyllaceae that has been traditionally used for the treatment of diseases such as ulcer, diarrhoea, wounds and fever since ancient times. This study presents antioxidant activities of water and methanol extracts of in vitro propagated C. demersum. Shoot tip explants of C. demersum for in vitro plant regeneration were cultured on liquid Murashige and Skoog (MS) medium containing 0.25-1.25 mg/L 6-Benzylaminopurine (BAP) and 0.10 mg/L Thidiazuron (TDZ) combinations for eight weeks. Maximum number of plantlets per explant (110.67) was obtained on MS medium supplemented with 0.75 mg/L BAP + 0.10 mg/L TDZ. In order to determine antioxidant activities of C. demersum, antioxidant contents (β-carotene, flavonoid, lycopene and total phenols), metal chelating and reducing power capacities of methanol and water extracts obtained from C. demersum were investigated. It was detected that water extract was more effective in all activities. Total phenols (76.55 μg/mg) in water extract were measured as the highest antioxidant component. Based on the water extracts data, as IC 50 value for chelating on ferrous ions was 9.24 mg/mL, EC 50 value for reducing power activity was 8.23 mg/mL. It was also determined that the metal chelating and reducing power activities of the both extracts are increased depending on the concentration. Therefore, all these data suggest that both tested extracts of in vitro propagated C. demersum would exert beneficial effects by virtue of their antioxidant properties and may be utilized as a promising source of therapeutics.

“…This result concurred with Tekwu et al [30] and Djellouli et al [31] who reported that chloroform fraction derived from the methanol extract of A. radiata was found to be most effective followed by ethyl acetate and butanol fractions. Some extracts showed weakly anticandidal activity [8]. El Hassany et al [14] reported that 9α-hydroxyparthenolide isolated in A. radiata at a concentration of 50 and 100 µg/disc, inhibited the growth of Bacillus cereus (IPL 58605), Streptococcus C (IPT 2-035), Proteus vulgaris (CIP 58605), Enterococcus faecalis (CIP 103214) and Escherichia coli (CIP 54127).…”

“…Anvillea radiata is endemic between Algeria and Morocco [2,9] and used in traditional medicine for the treatment of various diseases e.g., gastroenteritis [10], spasms and colic, arthritis and rheumatoid vaginal discharge, colds, hepatitis, diabetes and stomach ailments lung disease and indigestion [9][10][11], antifungal activity [1,12,13], antimicrobial activity [8], etc. In previous phytochemical studies, parthenolid-9-one, 9α-hydroxyparthenolide, 8α,9α-epoxyparthenolide from A. radiata are reported [14].…”

Anvillea garcinii subsp. radiata (Coss. & Dur.) are an endemic species of Sahara region especially in Morocco and Algeria. This plant is widely used in traditional medicine. The extraction of phenolic compounds from A. radiata flowers is carried out using solvents of different polarity (chloroform, ethyl acetate, butanol). The yields of extraction from the flowers were 19.34, 0.278, 0.149, 1.750 and 3.308 % for the crude, chloroform, ethyl acetate, butanol and aqueous extracts, respectively. The amount of total phenolics, flavonoids, tannins and in vitro antioxidant and antibacterial properties of extracts of A. radiata flowers. The antioxidant activities were evaluated by measuring the ability of the extracts to scavenge the DPPH, ferric reducing power FRAP and phosphomolybdenum assay. The maximum extractable total phenolics and flavonoids were recorded in ethyl acetate fraction, while the tannins were present in chloroform fraction. Among the five extracts of A. radiata flowers, the maximum DPPH free radical scavenging activity was shown in ethyl acetate and butanol fractions (IC50 = 0.20 ± 0.001 and 0.31 ± 0.004 mg/mL, respectively). The highest activity of FRAP assay and phosphomolybdenum reduction was observed in butanol fraction (358.58 ± 12.55 and 95.09 ± 0.67 mM, respectively). The results were compared with natural and synthetic antioxidants. In antibacterial properties, the chloroform extract has the highest activity. These results implied that these plant extracts may possess health promoting effects and might be potential sources of potent natural antioxidant and antimicrobial.
