| Abstract Ecballium elaterium is a perennial herb with multiple medicinal properties. It was widely used in folk medicine as cathartic, anti-inflammatory and analgesic agents. The present study was devoted to investigate the effect of diethyl ether, acetone, and methanol solvent on the extraction, phytochemicals profiles, antioxidant and antimicrobial activities of Ecballium elaterium seeds and peels fruits. The total phenolic, flavonoid, flavonol, condensed tannins and carotenoids contents were estimated. Maximum phenolic (107 ± 4 mg GAE/g) and flavonoid (18 ± 0 mg QE/g) contents were also found in the methanol peels fruits extract. Results showed that methanol peels fruits extract have the highest antioxidant activity with IC50 values of 1.2 ± 0.1 and 1 ±... |

| Abstract Erodium glaucophyllum collected from Tunisian Sahara was never presented in the relevant literature yet. In this study, the phytochemical profiles, chemical compositions, antioxidant and antimicrobial activities, and Kill-time assay of the hydroalcoholic extract of flowers and leaves were investigated. The highest content in phenols, flavonoids and tannins was shown in flowers extract (350 ± 5 mg GAE/g, 34 ± 1 mg QE/g and 221.8 ± 0.0 mg β-carotene E/g, respectively). The carotenoids amount in leaves was about 6-fold higher than it’s in flowers. Conducted LC/MS analysis revealed the presence of 17 compounds in flowers and leaves extract with the main were quinic acid and naringin followed by rutin, hyperoside, gallic acid and... |

| Abstract Ecballium elaterium species are mostly used as therapeutic agents and food ingredient. The current work was designed to investigate phytochemical contents, antioxidant, antibacterial, and anti-inflammatory properties of methanol fruits extract of Ecballium elaterium. Good antioxidant activity was observed with IC50 values of 156 ± 4 and 377 ± 6 μg/mL for DPPH and ABTS, respectively, and EC50 of 126 ± 4 µg/mL for FRAP assays, which is related with their richness in total phenolic, flavonoid and condensed tannins contents. The results of antibacterial activity showed the effectiveness of methanol extract against Bacillus cereus with value of inhibition zone diameter of 15 ± 0 mm and a MIC and MBC values of 6 ± 0 and 12 ± 0 mg/mL, respectively. The... |

| Abstract This study was designed to investigate chemical composition, the total phenolic content, flavonoid content, antioxidant activity and to analyze through FT-IR spectroscopy method the freeze-dried extract of Ecballium elaterium fruit from three different localities. The highest level of phenolic and flavonoid contents was recorded for the fruit juice from the Cap-Bon region, with 106.4 ± 0.4 mg GAE/g and 6.5 ± 0.2 mg QE/g, respectively. Antioxidant activity varied in dose-dependent manner with IC50 values for DPPH scavenging of the freeze-dried fruit juice extracts from Cap-Bon, Kef and Sidi Bouzid were 38.6 ± 0.2, 50.1 ± 0.7, and 50.7 ± 0.2 µg/mL, respectively. The results from the FRAP test showed that the freeze-dried extracts of Cap-Bon... |

| Abstract Cladodes Powder Extracts (CPE) are known for their medicinal properties such as being an auxiliary treatment for obesity and gastrointestinal or cardiovascular disorders as well as lowering cholesterol levels. The presented results proved that CPE was found to be a rich source of carbohydrate, ash, moisture and minerals namely Magnesium, Calcium and Zinc which highlighted its good nutritional value. Moreover, the solvent extracts displayed appreciable level of polyphenols, flavonoids and tannins contents compounds which may explain their higher and varied antioxidant and antimicrobial properties. The time-kill assay revealed that the bactericidal concentration required for cladode to kill M. luteus should be less than 3.12 mg/mL (2MIC).... |
