The aim of this study was to determine the chemical composition of the CO2 extract obtained from the underground part of Ferula asafoetida L., a plant widely used in traditional Kazakhstani medicine, with a particular focus on the amino acid and fatty acid profiles. Materials and methods. The plant material was collected in accordance with current Good Agricultural and Collection Practice (GACP) guidelines and underwent thorough pre-processing. A subcritical CO2 extraction method was applied to preserve thermolabile and volatile components while minimizing solvent residues. Chemical analysis was performed using GC-MS, and the amino acid and fatty acid profiles were determined by gas-liquid chromatography (GLC) based on standardized methods. Results. The resulting CO₂ extract had a high proportion of unsaturated fatty acids (90.2 %), primarily oleic acid (46.1 %) and linoleic acid (43.0 %), along with a complete set of 20 amino acids, including 25.92 % essential amino acids. The major bioactive compounds identified were 9,12-Octadecadienoic acid, ethyl ester (18.61 %) and ethyl oleate (13.18 %), which have potential antioxidant and anti-inflammatory properties. These findings suggest the extract’s suitability for pharmaceutical and nutraceutical applications. Conclusions. Although the extract shows promising potential for pharmaceutical applications, further verification through comprehensive pharmacological studies is necessary

Ferula asafoetida L. has been studied for centuries by many scientists as food products and in traditional medicine, which are relevant for Kazakhstan as well. Recent studies have shown that Ferula asafoetida L. has neuroprotective, memory-enhancing, digestive enzymatic, antioxidant, antispasmodic, hypotensive, hepatoprotective, antimicrobial, antitumor, cytotoxic, and anthelmintic effects. The aim of this study is to determine the component composition by GC-MS method and to study the antimicrobial properties of Ferula asafoetida L. extract obtained by CO2 extraction, which grows in Kazakhstan. Materials and methods. To determine the possibility of using Ferula asafoetida L., we carried out the component composition of the extract obtained by CO2 extraction in subcritical conditions of the underground part of Ferula asafoetida L. by a certain GC-MS method and also investigated the antimicrobial effect of this extract. Results. The plant raw materials were collected in accordance with GACP requirements. Conducted subcritical CO2 extraction of plant raw materials showed a 2.5% extraction yield. The study of the component composition by GC-MS revealed 46.3% of sulfate compounds. The determination of antimicrobial activities showed high efficacy against gram-positive (Staphylococcus aureus subsp. Aureus, Bacillus subtilis subsp. Spizizenii), gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae subsp. pneumoniae, Salmonella enterica subsp. enterica) and fungi (Candida albicans, Aspergillus niger). Conclusions. The possibility of using the obtained CO2 extract of Ferula asafoetida L. in the field of pharmaceutical products as a substance and a drug that has a huge antimicrobial effect

A special place among vegetable oils was occupied by natural tobacco oil. Natural tobacco oil in folk medicine is used as an antiseptic and antibacterial agent. To determine the possible alternative use of tobacco, the seeds representing Kazakhstan tobacco cultivars, extracted from ground Nicotiana tabacum seeds, were investigated by using the cold press. The quality of the oil was assessed in terms of free fatty acid content. The percentage oil yield was 36.75 ± 0.50%. Tobacco seed oil is highly unsaturated, nonacidic, and would require little purification. The oil can be used for the production of soap, antiwrinkle cream for the face, hair shampoo, shoe cream, and as a high-resolution base oil for perfumes and light industry and can be commercialized due to its high oil yield, for use as anti-inflammatory drugs.
