Summary:The invention relates to a process for preparing active plant products with antioxidant activity. According to the invention, the process consists of the following steps: extraction of narrow leaf plantain with water while continuously stirring for 1 h without laser and for 1 h assisted with laser radiation at 488 nm, at the temperature of the extraction mass, resulting in a total extract, total extract precipitation from ethanol 80% in a 1:4 w/v ratio, resulting in a selective extract enriched in minerals and microelements, and then the recovery of the alcoholic supernatant and the resumption of the product in concentrated ethanol, resulting in a final selective extract enriched in polyphenols, with a content of 5 mg GAE per ml of extract. Invenţia se referă la un procedeu de obţinere a unor produse active vegetale cu activitate antioxidantă. Procedeul, conform invenţiei, constă în etapele: extracţia frunzelor de pătlagină îngustă cu apă în regim de agitare continuă, 1 h fără laser şi 1 h asistată cu radiaţie laser la 488 nm la temperatura masei de extracţie, rezultând un extract total, precipitarea din etanol 80% a extractului total în raport 1:4 g/v, rezultând un extract selectiv îmbogăţit în minerale şi microelemente, recuperarea supernatantului alcoolic şi reluarea produsului în etanol concentrat, rezultând un extract selectiv final îmbogăţit în polifenoli, având un conţinut de 5 mg GAE per ml extract.
