Screening Studies of Chemical Composition, Antibacterial Activity and Acute Toxicity of Siberian Fir Oil Fraction

Abstract

Siberian fir is a common species in the taiga zones. A man produces oils, balms, extracts, cell sap, phytoconcentrates, syrups, etc., used in the food, phar-maceutical, perfume and cosmetic industries, in the household chemicals produc-tion and in medicine from the waste left after harvesting the wood. Siberian fir waste processing products have antioxidant and anti-inflammatory properties and can be components of the biologically active additives and functional prod-ucts manufacture. The research aims at studying chemical composition of biologically active substances, macro- and microelements, as well as the antibacterial activity and toxicity of the oil fraction obtained from Siberian fir. The study ob-ject is the oil fraction obtained from the Siberian fir extract by extraction with liquid carbon dioxide. A man run screening and identification of target biologically active substances using methods of analytical HELC, IR spectroscopy (IR), gas-liquid chromatography-mass spectrometry (GLC-MS). The researchers de-termined antibacterial activity of the samples in relation to ten clinical microor-ganism isolates by the agar diffusion method. They studied toxicity on outbred mice, males and females CD-I at doses of 2.5, 1.25, 0.625 g/kg animal weight. The thesis consists of microbiological parameters of Siberian fir extract; experi-mental data on the qualitative and quantitative content of biologically active sub-stances, macro- and microelements in the oil fraction of Siberian fir. The study results of the oil fraction indicate that it is a rich source of biologically active sub-stances with antioxidant and anti-inflammatory properties; it belongs to the third hazard class (moderately dangerous substances). Microbiological indicators are within the permissible norm. The oil fraction of Siberian fir extract can be rec-ommended in the production of biologically active additives, functional products, but only after deep processing associated with the components fractionation of the raw materials used.
