    Determination of volatile components and ethnobotanical properties of Rhus coriaria l. in Isparta province of Turkey
    (Al-Farabi Kazakh Natl Univ, 2023) Sarikaya, A. G.; Kaytanlioglu, E. H. Tigli; Fakir, H.
    Rhus coriaria L., which is from the Anacardiaceae family, is an important as a spice and medicinal plant in Turkey. In recent years, when drugs are insufficient, interest in natural plants has increased and their importance has increased in terms of being a source of raw materials in many industrial areas. In this study, it was aimed to determine the volatile components of sumac fruit samples collected from Kasnak, Kovada Lake, Barla Mountain, Asagigokdere and Sutculer locations in Isparta province and their ethnobotanical use in the region. 159 volatile components of Rhus coriaria, were determined by the Head Void-Solid Phase Micro-Extraction (HS-SPME) technique combined with gas chromatography/mass spectrometry (GC/MS). The main components were a-pinene (Sutculer 16.95%; Barla Mount 24.41%, Kovada 16.37%, Kasnak Forest 5.81%, Asagigokdere 18.20%, limonene (Sutculer 7.50%; Barla Mountain 8.35%; Kovada 18.07%; Kasnak Forest 11%, 83; Asagigokdere 12.38%), 1,3,6-Octatriene, 3,7-Dimethyl- (Sutculer 13.76%; Barla Mountain 19.36%; Kovada 7.97%; Kasnak Forest 5.53%; Asagigokdere 15.01%) and beta-caryophyllene (Sutculer 7.70%; Barla Mountain 21.55%; Kovada 12.99%; Kasnak Forest 33.63%; Asagigokdere 1.18%). To determine the ethnobotanical use of Rhus coriaria in the region, a face-to-face survey of 22 questions was applied to 150 people selected by the stratified sampling model from the local people. The local people use the leaves and flowers of Rhus coriaria as tea, the fruits as a spice, and the sour sauce obtained from the fruits for food purposes. They also stated that they use it for various ailments, especially against Covid-19, for health purposes.

    Determination of volatile components of Viscum album L. distributed naturally in Egirdir (Isparta) province, Turkey
    (Al-Farabi Kazakh Natl Univ, 2022) Kaytanlioglu, E. H. Tigli; Sarikaya, A. G.; Fakir, H.
    This study aims to determining the volatile oil components of naturally distributed Viscum album L. belonging to the Santalaceae family. The study was carried out in villages of Egirdir province of Isparta in Turkey. The isolation of volatile components was performed from of the leaves of the mistletoe collected from five different tree species. Qualitative analysis of volatile components were carried out by the Head Void-Solid Phase Micro Extraction (HS-SPME) technique combined with gas chromatography/mass spectrometry (GC-MS). The identification of the constituents was carried out by comparing the retention index (RI) and mass spectral data (MS) to those reported in the published literature. As a result of the Head Void-Solid Phase Micro Extraction (HS-SPME) technique combined with gas chromatography/mass spectrometry (GC-MS). 54 different components were determined and (E)-2-Hexenal, Benzaldehyde and Nonanal were found as the main components. It is known that there are limited number of studies on the determination of essential oil and volatile components of the Viscum genus. According to this study, the use of mistletoe as a raw material source in different industrial areas have importance.

    Modeling of present and future potential distribution areas of Thymus praecox opiz. in Turkey according to the Maxent algorithm
    (Al-Farabi Kazakh Natl Univ, 2023) Uzun, A.; Sarikaya, A. G.; Kavakli, S. A.
    Thymus L. genus of the Lamiaceae family, which has a cosmopolitan distribution that includes annual or perennial herbs, rarely shrubs or trees, known for their pleasant smell, has medicinal and aromatic species. Although the ethnobotanical use of individuals of the genus Thymus is quite common, its consumption is often preferred as spice and medicinal tea. In this study, Thymus praecox Opiz. forms the material of the study. In this article, potential present and future distribution areas were modeled in MaxEnt 4.1 to determine the effects of climate change on the distribution areas of T. praecox in Turkey. In the model, 2041-2060 (similar to 2050) and 2081-2100 (similar to 2090) periods of SSP2 4.5 and SSP5 8.5 scenarios in CanESM5.0.3 (The Canadian Earth System Model version 5) climate change model were used, together with sample points and bioclimatic variables. According to the study outputs, it is estimated that the estimated potential suitable and very suitable distribution areas of T. praecox today are 108411.705 km2 and according to the CanESM5.0.3 model, it will experience losses in very suitable and suitable distribution areas in the future, and very suitable distribution areas cannot be found in the SSP5 8.5 scenario 2081-2100 periods.
