Biochemical analysis of some vegetal extracts obtained from indigenous spontaneous species of Thymus serpyllum L.

After harvesting, medicinal and aromatic plants are appropriately processed or dried/dehydrated in order to obtain phytotherapeutic products of different use. The plant therapeutic action may be due to a group of substances or a phytochemical combination and sometimes to ballast substances that enhance the biologically active substances, thus increasing their activity and making them last. For obtaining optimum yield of bioactive substances it must take care of the procedure of extraction used, type of solvent and also the physical and mechanical features of vegetal product cells. This paper presents the comparative biochemical and physicochemical analysis for four vegetal extracts obtained from aerial parts of thyme, Thymus serpyllum L harvested from Romania spontaneous flora as dried, minced and broken into four fractions (sorts). It was determinated the content of substances extracted in the three solvents for four-dimensional fraction of thyme then were identified the solvent and fraction out of which the maximum of bioactive substances was extracted. After that, four ethanol extracts obtained from the four fractions of thyme were analyzed at Gas-Chromatograph GC-MS. Biochemical analysis of ethanol extracts obtained from Breckland thyme (Thymus serpyllum L.) has shown the existence both of common biochemical compounds and different biochemical compounds.
