“…The results are similar to those of Mansouri et al 24 , who found that the methanol extract obtained by maceration gives the highest total tannins content (1.99±0.11 mg CE/g dry weight). In another study, Souhila and Mustapha, 25 reported that the Aqueous extract had the best tannin content of 4.09 mg CE/g dry weight. Also, the infusion extract had the highest content of tannins, which could be due to the use of high temperature in infusion extraction, which contributed to the good diffusion and solubility of the extract.…”

Euphorbia resinifiera is a medicinal plant exploited by the native population to treat various diseases. The study compared the effects of seven different extracts of Euphorbia resinifiera by evaluating their antibacterial activity. The study reported the alkaloid percentage, total protein content, carotenoid content, and tannin content in the aerial part of Euphorbia resinifiera. The antibacterial activity of the seven extracts (100 mg/mL/disc) was evaluated by disc diffusion method against six pathogenic bacteria: 2 Gram-positive (Staphylococcus aureus and Microbacteriumresistant) and 4 Gram-negative (Klebsiella pneumonia, Escherichia coli, Alcaligenesfaecalis, and pseudomonas chloritidismutans). Aqueous methanol extract obtained by maceration showed the best antibacterial activity against all tested bacteria. Whereas the percentage of total protein content was very low, 1.28%, and the alkaloid yield was 0.08±0.013 g/100 g of dry weight. The results revealed that the lethal dose (LD50) was higher than 300 mg/kg for the aqueous extract obtained by maceration. For other extracts, the LD50 was higher than 2000 mg/mL (maceration methanol, maceration Methanol-water, sonication methanol, sonication water, sonication Methanol-water, infusion.). Overall, the results indicated that Euphorbia resinifiera possesses antibacterial activity against the isolates studied.

“…Caffeoylquinic acid and its derivatives have a variety of bioactivities. These compounds are renowned as potential antioxidants [ 43 ], additionally to their important antitumor, antimicrobial, anti-inflammatory activities, and others [ 44 ]. 3-O-Caffeoylquinic acid, as a key active compound identified in the E. creticum IVDV-treated leaves extract could therefore underly the high antioxidant capacity found.…”

“…Numerous studies in the literature correlate the biological properties of medicinal plants to their phytochemical profile. Caffeoylquinic acid and its derivatives are well known as potential antioxidants [ 42 ], in addition to their significant antimicrobial, antitumor, anti-inflammatory activities [ 43 ]. 3- O -caffeoylquinic acid, the major active compound identified in C. longiflorus stems IR extract, exhibits high-antioxidant activity.…”

Extraction of polyphenols from Centranthus longiflorus stems was conducted using ultrasound and infrared Ired-Irrad® techniques, and compared to the conventional water bath method. Response surface methodology was used to analyse the effect of time, temperature, and ethanol percentage, as well as to optimize the three extraction methods. The highest phenolic content (81 mg GAE/g DM) and antioxidant activity (76% DPPH inhibition) were recorded with the Ired-Irrad® extract obtained under the optimal conditions: 55 °C, 127 min, 48% (v/v) ethanol. Biological activities (antioxidant, antibacterial and antibiofilm) of the three extracts were assessed. All C. longiflorus stems extracts showed limited antibacterial effects regardless of the extraction method (MIC = 50 mg/mL), whereas Ired-Irrad® extract exhibited the highest biofilm eradication and prevention capacities (93% against Escherichia coli and 97% against Staphylococcus epidermidis, respectively). This bioactivity is likely related to abundant caffeoylquinic acid and quercetin rutinoside, as identified by RP-UHPLC-PDA-MS analysis. The results obtained further promote the effectiveness of Ired-Irrad® as a highly flexible and cost-efficient extraction technique.
