In 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.).
