The component composition and antihypoxic activity of Siberian fir (Abies sibirica) essential oil fractions were researched. The foliage of Siberian fir, collected on the territory of the Ilyinsky district of the Perm region in a dark coniferous forest was the raw material for obtaining the essential oil. Samples for the research were collected in December 2018 from trees 40–50 years old. The essential oil was obtained with the Clevenger apparatus. Determination of the component composition of Siberian fir essential oil fractions was made by using chromatography-mass-spectrometry. Experiments for determination of antihypoxic activity of Siberian fir essential oil fractions were made on a hypoxic hypoxia model with hypercapnia. According to the results of the research, it was found that the first fraction is more saturated with monoterpene compounds, but the proportion of sesquiterpenoids increases in following fractions. The main components of all fir oil fractions are: bornylacetate, limonene, ∆3-carene, karyophyllene. It was found that the fractions 1 and 2 have the highest antihypoxic activity in comparison with the reference sample. For further research, we offer fraction 1, because it contains the high level of bornylacetate, and the lowest content of ∆3-carene, which inhibits the ubiquinol cytochrome-C reductase complex, interrupting mitochondrial and cell respiration.

The article presents results of the study of a comparative analysis of essential oil obtained from fresh and dried leaves of medicinal sage (Salvia officinalis L.), growing in the Botanical Garden of the First Moscow State Medical University named after Sechenov. The studies were carried out using gas chromatography– mass spectrometry. Qualitative and quantitative difference in the component composition of the essential oil obtained from fresh and dried raw materials was determined as a result of the study.

Gas Chromatographic Method

Numerous articles on Salvia officinalis L. have been published regarding the composition of their essential oil. The considerable variation found may be due to the quality of the plant material as well as to the methods used for analysis. A simple GC-MS method was developed and optimized in the QbD approach, for the determination of sage essential oils. The optimization of GC-MS analysis was performed using different mobile phase flows, injection volumes, split ratios and temperature programs. The optimized method proved to be simple and can be successfully applied for the determination of sage essential oils.
