Overview
The drugsValerinae radix, Crataegi fructus,Leonuri herba and Melissae folium were used to producea liquid plant extract. The experiment revealed that the extraction with 70% ethanol achieved thehighest concentration of extractable active principles. The optimal conditions for obtaining a sedativeextract are established when the method of repercolation is used, and in the production itselfthe batch of the drug is divided into equally large doses and a pre-prepared mixture of plant drugsis extracted. The extract prepared by this manner remains stable for the whole period of storage,i.e., 24 months.
