摘要:
The invention relates to a process for preparing a biopreparation with antimicrobial effect on Phytophthora infestans, pathogenic agent of tomato late blight. The process, as claimed, consists in that a mixture of the following dry and finely ground plants: Urtica dioica (aerial parts), Sambucus ebulus (fruit), Xanthium strumarium (aerial parts and unriped fruit) and Humulus lupulus (cones), is subjected to alcoholic extraction with 50% ethanol in a ratio of 1:10 as compared to the plant mixture, after which it is subjected to ultrasonication for 30 min, at a temperature of 35°C, power of 34 Watt, the resulting extract is left to rest, at a temperature of 5...10°C, for 6 days, after which is filtered under vacuum, the resulting filtrate having the potential to inhibit in vitro the pathogenic agent of late blight.Invenţia se referă la un procedeu de obţinere a unui biopreparat cu activitate antimicrobiană asupra, agent patogen al manei tomatelor. Procedeul conform invenţiei constă în aceea că un amestec de plante:(părţile aeriene),(fructe),(părţile aeriene şi fructele nematurate) şi(conurile), uscate şi măcinate fin, se supune extracţiei alcoolice cu etanol 50% în raport 1:10 faţă de amestecul vegetal, după care se supune ultrasonicării timp de 30 min, la temperatura de 35°C, putere 34 Watt, extractul rezultat se menţine în repaus, la temperatura de 5...10°C, timp de 6 zile, după care se filtrează sub vid, filtratul rezultat având potenţial de a inhibaagentul patogen al manei.
