“…According to the results of the study of Rached et al, the root methanolic extract of Z. lotus, exhibits moderate activity (9.14 ± 0.72 µg/mL) when compared to BHA used as a positive control (4.15 ± 0.25µg/mL) [52] . This result indicated that root extracts of Z. lotus have significantly strong antioxidant power.…”

Objective: To find a new natural source of antioxidant, the phenolic contents and antioxidant activities of some secondary metabolites extracted from roots of Ziziphus lotus were evaluated. Methods: The total polyphenol contents were determined spectrophotometrically. Pyrrocatechol, catechin and cyanidin equivalents were used for these parameters. The antioxidant activities of the extracts were determined by several in vitro systems of assays, namely DPPH radical scavenging activity method, b-Carotene Bleaching assay (BCB), Ferric Reducing Antioxidant Power assay (FRAP) and Total Antioxidant capacity test (TAC). Results: The quantitative estimation showed that the roots of Z. lotus were rich in polyphenols (20.09 mg PE/g DW) and proanthocyannidins (1.56%) and they contained a small amount of flavonoids (0.02 mg CE/g DW). The most fractions exhibited high antioxidant activities, and some even showed higher potency than the standard synthetic antioxidants in some instances. In DPPH assay, all extracts had shown significant inhibition (58.535 -94.730% at 1 mg/mL). In addition, the IC 50 values ranged from 0.211 to 0.816 mg/mL, compared to 0.110, 0.214, 0.214 and 0.413 mg/mL for gallic acid, tannic acid, butylated-hydroxyanisol and ascorbic acid respectively. In (BCB) assay, the extracts showed strong inhibition (55.55 -100.00% at 1 mg/mL) and the IC 50 values ranging from 0.123 to 0.850 mg/mL compared to 0.433 mg/mL for gallic acid. A dose dependant curve was obtained for all extracts in the FRAP assay. However, the antioxidant potencies of ascorbic acid and extracts were comparable at low concentrations. The majority of extracts showed the highest value of antioxidant activity, based on TAC test (0.073 -0.398 mg ascorbic acid / mg extract). Conclusion: The results indicate that Z. lotus roots could be an important sources of natural antioxidants.

This work aims at evaluating the anti-inflammatory activity of an endemic species of the central sahara: Myrtus nivellei Batt & Trab. The methanolic extract of this plant was extracted by Soxhlet apparatus and concentrated under reduced pressure using a rotary evaporator.In the carrageenan-induced paw edema test, five different groups of mice were established and the extract was administered orally in three different doses. The dose of 400 mg/kg was able to reduce significantly the paw edema with a comparable effect to that observed with Diclofenac (positive control). This is the first report to demonstrate a significant anti-inflammatory activity of the methanolic extract prepared from Myrtus nivellei.

“…The twenty analyzed plant species have the same geographic origin and grow in the same natural condition, nevertheless the plants belong to different families. It is well known that the amount of phenolic compounds vary with respect to families and varieties [10][11][12][13][14][15][16][17][18] .…”
