Within this framework, the current study was undertaken to examine in vivo the anti-inflammatory and analgesic effects of aqueous extracts of the leaves and seeds of V. agnus cactus and C. nardus. In this relation, aqueous extracts were prepared from the leaves and fruits of V. agnus cactus and the leaves of C. nardus. The inflammatory process was induced using the carrageenan method. The analysis of the obtained results revealed that the aqueous extract of leaves of V. agnus cactus exhibited the highest antioxidant content (80.22 ± 11.7 mg GAE/g for TPC, 72.14 ± 9 mg RE/g for TFC, 680 ± 19.6 mg QE/g for flavones and flavonols, 355.33 ± 23.36 mg AAE/g for TAC, 0.33 ± 0.04 mg/mL for IC50-DPPH, and 0.97 ± 0.04 mg/mL for EC50-FRAP) and anti-inflammatory effect with dose-dependent manner. These results suggest that these plants have the potential to alleviate pain and inflammation when used for therapeutic purposes. Manuscript profile -

2 - Simultaneous optimization of extraction of bioactive compounds and antioxidant activity of Ammi visnaga (L.) Lam aerial parts using response surface methodologyZineb El Jabboury Smail Aazza Driss Ousaaid Oumaima Chater Uroš Gašić Peđa Janaćković Zora Dajic Stevanovic Stefan Kolašinac Meryem Benjelloun Lahsen El GhadraouiTrends in Phytochemical Research , Issue 1 , Year , Spring 2024In this report, different extracts from the aerial parts of Ammi visnaga (L.), e.g., flowers, leaves, and stems were prepared using water, methanol, and ethanol.

To optimize the extraction process, the design of mixtures was carried out using different extracting solvents and their combinations. The special cubic model explained the variance of the TPC and the antioxidant activity of the extracts at a level of R2 > 95%. In general, the analysis of the model-derived response surfaces revealed that in binary mixtures (50% ethanol + 50% methanol), the yielded values of phenolic compounds and the antioxidant activity increase with the water proportion of different prepared mixtures. The ability of the quaternary mixture to extract the phenolic compounds was also positively and significantly influenced by the water content, creating a mild polar medium for the extraction of phenolic compounds. The phenolic profile of different extracts under study revealed the presence of a cocktail of active ingredients, including chlorogenic acid, caffeic acid, rutin, p-coumaric acid, etc. especially the flower extract of A. visnaga (L.).
