“…The results for T. vulgaris EO composition are also in line with previously published data [ 20 , 21 , 39 ]. However, because, in the wild thyme EO, several chemotypes are described [ 26 , 27 , 28 ], this oil could be defined as a thymol chemotype.…”

“…However, it is well known that several chemotypes of Thymus serpyllum have been described until now [ 26 , 27 , 28 ]; as differences in chemical composition have a notable influence on investigated biological activities, new data are of great importance. Besides, it is well known that EOs’ chemical composition, contributing to their medicinal value and being responsible for the biological properties, highly depends on many factors such as geographical and climatic conditions, harvesting, isolation techniques, as well as storage [ 29 , 30 ].…”

Bovine mastitis is the most widespread and economically important disease worldwide. The present study aimed to determine bioactive compounds in two essential oils (EOs) from wild (Thymus serpyllum) and common thyme (Thymus vulgaris) and to assess the antioxidant potential as well as antibacterial efficacy of the EOs against mastitis-associated bacteria. The study also included antibiotic susceptibility tests. The strains were previously isolated from lactating animals with clinical and subclinical mastitis. The antioxidant potential of the commercial EOs of wild and common thyme was evaluated by five in vitro assays. The antibacterial activity was performed using the microdilution technique, while antibiotic susceptibility testing was performed by the Kirby–Bauer disc diffusion method. The dominant compound in wild thyme was thymol (45.22%), followed by p-cymene (23.83%) and γ-terpinene (3.12%), while in common thyme, it was thymol (54.17%), followed by γ-terpinene (22.18%) and p-cymene (16.66%). Among the fourteen mastitis-associated bacteria, strain IX Streptococcus spp. (β-hemolytic) was the most sensitive to the tested EOs (minimum inhibitory concentration (MIC)/minimal bactericidal concentration (MBC) were 0.78/1.56 and 0.39/0.78 mg/mL for T. serpyllum (TS) and T. vulgaris (TV), respectively). Regarding Streptococcus spp. β heamoliticus, MICs for TS ranged from 0.78 to 1.56 mg/mL, while for the same oil, MBCs ranged from 1.56 to 12.5 mg/mL. In the case of T. vulgaris, MICs ranged from 0.39 to 3.125 mg/ mL, while MBCs ranged from 3.125 to 6.25 mg/mL. TV is more active against E. coli, E. sakazakii, and Streptococcus spp., while it is less effective against Staphylococcus spp. than TS. The study revealed that the tested EOs possess remarkable antioxidative and antibacterial activities and could be used in the development of pharmaceutical formulation as an alternative to conventional mastitis therapy.

Chelidonium majus L. is a medicinal plant well-known as a valuable source of isoquinoline alkaloids, which has a variety of pharmacological properties including anti-viral and anti-bacterial effects. However, considerable intraspecific bio-morphological variability in C. majus complicates raw material identification and verification. For the first time, we have brought into cultivation five populations of C. majus subsp. majus originated from different regions, and performed their agro-morphological, microanatomical and molecular cytogenetic characterization. All examined populations produced high seed (18.6–19.9 kg/ha) and raw material (0.84–1.08 t/ha) yields; total alkaloid contents were within 0.30–0.38%. Nevertheless, significant differences in plant morphology and yield-contributing traits were observed. The performed microanatomical analysis of leaves and flowers in double- and normal-flowered plants revealed micro-diagnostic features (including tissue topography, types of stomata, laticifers, structure of leaf mesophyll, hairs, sepals and petals) important for identification of C. majus raw materials. The analysis of chromosome morphology, DAPI-banding patterns, FISH mapping of 45S and 5S rDNA and also chromosome behavior in meiosis allowed us to identify for the first time all chromosomes in karyotypes and confirm relative genotype stability of the studied plants. Our findings indicate that the examined C. majus populations can be used in further breeding programs.

Abstract. Pozdnyakova Y, Omarova G, Murzatayeva A, Tankibaeva N. 2022. Biodiversity of wild spice plants of the Central Kazakhstan region and their medicinal potential. Biodiversitas 23: 4609-4625. The Central Asian region stretches from the Caspian Sea in the west to the border of western China in the east. Central Kazakhstan occupies the space of steppe and semi-desert zones within the Turgay Plateau in the west and the Kazakh Uplands in the center and in the east. Due to the remoteness of the steppes of Central Kazakhstan from the oceans, the climate in the region is extremely continental and arid. Due to this, the diversity of plant species is quite small. In this work, we have studied the biodiversity of wild herbs growing in the climatic conditions of Central Asia. We also assessed the prospects of the found plant species as medicines. This study took place as part of the traditional summer practice of biology students in the period July-August 2019. The main method used in the field research was route reconnaissance. As a result of field research, 40 wild spice plant species belonging to 17 families were found. Among them, the most numerous are the families Lamiaceae - 9 species, Brassicaceae - 6 species, Apiaceae - 5 species, Asteraceae - 4 species, the families Rosaceae and Fabaceae - 2 species of herbs. All of these species are mentioned in a number of old recipes and can be revived and re-recommended for widespread use. A critical assessment of the literature on the medicinal properties of the studied spices irrefutably shows that they have enormous health potential. Based on the data obtained, it can be concluded that wild spice plants growing in the territory of Central Kazakhstan have a wide range of taste diversity and prospects for successful commercial exploitation.
