Studying the technology for obtaining pharmaceutical substances and determination of biologically active substances in them

ABSTRACT

In searching for alternatives to traditional chemical medicines, including feed antibiotics, scientists around the world are developing a new generation of medicines, phytobiotics. This work was aimed at studying the phytobiotics (pharmaceutical substances) production technology using the method of low-temperature vacuum water-ethanol extraction of Siberian medicinal plants, followed by low-temperature vacuum drying and determination of the main biologically active substances that had the required pharmacological effect on the organisms of farm animals and poultry. The objects of the study in this work were Siberian medicinal plants and ready phytobiotics (pharmaceutical substances). The article describes the technological conditions for obtaining pharmaceutical substances and their properties concerning the content of biologically active substances. It has been found that for obtaining pharmaceutical substances, extraction should be performed in three stages two water extractions and ethanol- water extraction. The article provides a list of medicinal plants and the amounts of biologically active substances that ensure certain pharmacological effects on the set of economically useful qualities in farm animals and poultry and contained in phytobiotics (pharmaceutical substances) based on extracts from medicinal plants.
