Laboratory of Galenic and New Galenic Preparations

 

The laboratory was formed in 2017 on the basis of the Asymmetric Synthesis Laboratory under the structure of the Scientific and Production Center "Armbiotechnology" NAS RA. The laboratory is engaged in the development of industrial technologies for the production of galenic and new galenic preparations from the least investigated endemic medicinal plant raw materials and the organization of their serial production.

 

RESEARCH MAIN DIRECTIONS

  • Obtaining and investigating some highly active galenic and new galenic preparations
  • Phytochemical characterization of plant raw materials for the detection, separation and quantitative evaluation of biologically active compounds in them
  • Development of industrial technologies for more active medicinal preparations from medicinal plant raw materials, obtaining of samples and certification
  • Introduction of the developed technologies for the production of phytopreparations and launching of the corresponding galenic preparations

 

MAIN INVESTIGATION RESULTS

  • Isolation and purification methods of native BAS, some vitamins, tinctures, water-alcoholic extracts and plant oils obtained by cold pressing have been developed and certificated.
  • More effective technologies for extracting amygdalin from bitter kernels, crystal lycopone from bulgarian pepper and BAS from oyster mushroom  have been developed.
  • Analogs of isolated BAS have been obtained by chemical modification.
  • Biological activity of the isolated BAS and their modified analogs has been evaluated.
  • Highly active medicinal oils (milk thistle, sea buckthorn, black and white sesame, apricot, peach, etc.) and preparations (black cumin, round-leaved wintergreen, chaga mushroom, etc.) as natural hepatoprotective, antitumor, analgesic and cosmetic products are produced by the developed methods and are widely used in the treatment of cancer , liver, stomach and other organs diseases and in cosmetology. The secondary products of their processing are in high demand in cattle breeding and poultry as multivitamin feed additives rich in micro- and macro elements. 

 

MAIN OBJECTIVES AND TASKS

  • Development of highly efficient technologies for isolation and purification of native BAS (extraction yield > 85 %) from medicinal plant raw material
  • Obtaining of galenic and new galenic preparations and implementation of biomedical research
  • Clarification of the yield dependence of BAS isolation on the vacuum processing of raw materials and their extraction in inert gas flow
  • Clarification of the yield dependence of BAS isolation on the extraction by the method of vacuum-pulsation
  • Development of methodology for antioxidant and biomedical investigations of extracts
