Biologically active ingredients of new introducing varieties of stevia.

Abstract

Georgia is a small country, therefore, the effective use of the special possibilities of natural and  climatic  conditions  for  growing  local  or  introduced  plants  is  especially  important  for  the  country. Today, unfortunately, in many cases, the soil is not used properly. It is cultivated with plants that are not studied or not suitable for environmental conditions. Crop production (leaf, fruit, etc.) is cost-effective when studying its chemical composition using modern physicochemical methods. The research is particularly relevant when it comes to plants containing biologically active compounds.  Therefore,  there’ should  be  established  qualitative  and  quantitative  content,  as  well  as  the  chemical  structure  and  biological  activity  of  a  plant.  There’ should  also  be  studied  the  optimal  period  of  accumulation  of these  compounds  and,  accordingly,  the  harvest  time  of  raw  material.  It  is  important  to  adapt  the  most  optimal  (chemical  composition,  yield  and  other)  varieties  in  this  region. It  is  necessary  to  develop  processing  technology  and  pay  attention  to  monitoring  of  biologically  active  compounds  during the processing and in the obtained product. Early studies have shown that the Stevia  plant  of  South  American  origin  is  particularly  effective  for  soil  and  climatic  conditions  of  western Georgia.
