Presentation flyer of NIRDBS/ “Stejarul” BRC


Short History

The "Stejarul" Biological Research Centre is a branch, without legal personality, of  NIRDBS (INCDSB) Bucharest and was founded in 1957 by the decision nr. 2271/1.11.1956, as a branch of the Faculty of Biology and Geography from the A. I Cuza University, Iassy, Romania.

Scientific certification and activity fields

As a whole, the researches are based on the study of medicinal and aromatic plants from multiple points of view and on the collaboration with private units of the SME type, to elaborate some phytotherapeutical products as part of food supplements.

The researches aim the vegetal raw material of different origins, such as:

  • Prelevation from the wild flora.

  • Transfer of some species from the wild flora to experimental cultures (experimental field).

  • Experimental cultures.

  • Biodiversity evaluations by studying some natural populations and their characterization from the morpho-phytochemical point of view.

  • Analysing the biosynthetic capacity of the medicinal plants reflected at the qualitative and quantitative level of the active principles (natural compounds / secondary metabolites).

  • Extracting vegetal raw materials, fresh and dry, due to the last edition of the European Pharmacopeaea.

  • Qualitative and quantitative phytochemical analysis by modern methods: thin layer chromatography (TLC), high performance liquid chromatography (HPLC), gas-chromatography coupled to mass-spectrometry (GC-MS).

  • Spectrophotometric analysis.

  • Phytobiological tests to evaluate the cytotoxicity/cytogenity of some vegetal extracts or phytopreparations.

  • Elaborating some formuli of food supplements in collaboration with processing units.

  • In vitro multiplication (micropropagation, submersible cultures/cell cultures) of medicinal and aromatic plants.

  • Qualitative and quantitative analysis of the experimental material originated from in vitro cultures.

  • Identifying, characterizing and multiplying genotypes/ecotypes with an optimum biosynthetic potential for the active principles with economic importance.

  • Inducing somaclonal variability, isolation and multiplication of vitroclones / experimental variants obtained.

  • Implementation of in vitro cultures to in situ and ex situ multiplication of the species with medicinal importance in conservation strategies (vulnerable/rare species) and sustainable capitalization.

  • Evaluating the medicinal and aromatic plat biodiversity by help of DNA fingerprint to make an inventory and to preserve the vegetal genetic resources.

  • Autentifying the botanical and phytochemical products with methods based on DNA barcoding.

  • Analysing waters – qualitative and quantitative hydrogeochemical determinations of a large series of macro and microcomponents using volumetric and instrumental methods (flamphotometry, spectrophotometry, etc): parameters comprised in the regime of the nutrients, of salinity, of the specific polluting agents of natural and anthropic origin and of other relevant chemical indicators, etc.

  • Analysing soils and sediments – determinations of mineralogical nature (water content, granulometric composition, etc), of organic nature (fractioning organic material, humic and non-humic compounds, different forms of carbon and nitrogen, etc), as well as on the anorganic nature (pH, Eh, carbonates, soluble saults, determinable compounds in total or changeable form), etc.
