Abstract (EN): A Box-Behnken design (BBD) was developed to study the influence of four parameters (Xi: % methanol; X-2: extraction time; X-3: extraction temperature; X-4: solid/solvent ratio) on two responses, namely extraction yield and phenolics content of the aerial parts of Chelidonium majus L The model presented a good fit to the experimental results for the extraction yield, being significantly influenced by Xi and X-4. On the other hand a parameter reduction was necessary to run the model for phenolics content, showing that only X-1 and X-2 had great influence on the response. Two best extraction conditions were defined: X-1=76.8% MeOH, X-2=150.0 min, X-3=60.0 degrees C and X-4=1 :100 and X-1=69.2%, X-2=150 min, X-3=42.5 degrees C and X-4=1:100. Moreover, the HPLC-DAD-ESI/MSn analysis conducted with the center point sample revealed the presence of 15 alkaloids and 15 phenolic compounds, from which the 9 flavonoids and 3 hydroxycinnamic acids are described for the first time. Only phenolic compounds were quantified by a validated HPLC-DAD method, the pair quercetin-3-O-rutinoside+quercetin-3-O-glucoside dominating all the 29 extracts. This study is of great importance for future works that seek to apply the phenolic profile to the quality control of C. majus samples.
