Aim of the study: This study was performed to determine the essential oil components of Salvia tomentosa Mill., Salvia argentea L. and Salvia bracteata Bank et Sol. Area of study: The study was carried out in two districts (Eğirdir and Şarkikaraağaç) located at Isparta province in Turkey. Material and methods: The isolation of essential oil components was performed from shoots with leaves and flowers. Qualitative analysis of essential oils was carried out by using a Shimadzu 2010 Plus GC-MS device. The identification of the constituents was carried out by comparing the retention index (RI) and mass spectral data (MS) to those reported in the literature. Main results: As a result of the GC-MS analysis, the major components of the essential oil were (-)-caryophyllene oxide (49.56%), β-vatirenene (7.87%), and α-Muurolol (6.78%) in S. tomentosa, sclareol (40.01%), germacrene-D (13.93%) and β-pinene (11.93%) in S. argentea and eucalyptol (1,8-cineole) (16.6%), β-pinene (14.7%) and cembrene (10.88%) in S. bracteata. Sclareol, which was determined at a high concentration in S. argentea in this study, is an economically valuable component that is widely used as flavoring in food and tobacco industry and as a perfume ingredient in the cosmetic industry. Highlights: According to this study, the cultivation of S. argentea can provide high economic returns
Onikişubat yöresinde (Kahramanmaraş) doğal olarak yetişen ve gıda olarak tüketilen bazı doğal bitki taksonlarına ait yöresel tarifleri tespit etmek amacıyla yapılmıştır. Çalışmada veri toplama aracı olarak 10 soruluk anket formu kullanılmıştır. Anket uygulaması kırsal kesimde yaşayan 101 kişiyle yapılmıştır. Anket sonucunda 9 bitki taksonu belirlenmiştir. Belirlenen bitkiler 2019 yılı vejetasyon döneminde toplanmıştır. Çalışma sonucunda yemek yapımında kullanılan bitkiler; ışgın (Pistacia terebinthus L. subsp. palaestina (Boiss.) Engler), tırşik (Arum maculatum L.), yarpuz (Mentha pulegium L.), ebegümeci (Malva sylvestris L.), gelinali (Papaver rhoeas L.), semizotu (Portulaca oleracea L.), su teresi, ıspatan (Nasturtium officinale R.Br.), ısırgan (Urtica dioica L.), çiriş (Asphodelus aestivus Brot.)'dir. Bu doğal bitkiler, sağlıklı ve doğal beslenmenin yanı sıra yöre halkı tarafından ekonomik kazançta sağlamaktadır. Onikişubat yöresinde doğal olarak yetişen bitkilerin gıda olarak tüketilmesi ve gelecek nesillere bu bilgilerin aktarılması amacıyla bu bitkilerle yapılan yöresel tariflere yer verilmiştir. Pistacia terebinthus'tan yapılan dürüm ve Mentha pulegium'dan yapılan çorba literatüre kazandırılmıştır.
In this study, it was aimed to determine the volatile compounds of the flowers of wintersweet (Chimonanthus praecox) belonging to the Calycanthaceae family which is an exotic species and used as an ornamental plant in the parks of Burdur (Gölhisar) in Turkey. Flower specimens were dried at room temperature, followed by determining their volatile compounds by HS-SPME/GC-MS analysis. As a result of the analysis, 33 volatile compounds belonging to the Chimonanthus praecox species were determined, and the first three main compounds were β-Ocimene at a rate of 61.87%, Sabinene at 7.65% and Caryophyllene at 5.03%. The findings that were obtained were compared to those obtained in other studies.
This study was carried out to classify woody vegetation in Gölcük Nature Park. Vegetation classification provides important information on sustainable forestry and biodiversity. In the study, 25 sampling areas with the dimensions of 20x20 meters were taken with the land inventory. For each sampling area, woody plant taxa and habitat characteristics were recorded in the inventory book. Multiple permutation test (MRPP) was applied in order to determine the most suitable of the groups obtained from the cut-off levels by cluster analysis. Indicator plant analysis was applied in order to determine the indicator plant species of the most effective vegetation group separation by the multiple permutation test. Pearson correlation analysis was applied to reveal the relationships between alpha diversity index values and environmental factors. Pinus nigra, Rosa canina, Populus nigra subsp. caudina and Malus sylvestris subsp. sylvestris were determined to be the most common species in the study area. In the study, the most appropriate vegetation classification was obtained in 3 groups. As a result of the mentioned statistical analyzes, it was determined that aspect differences are important in the formation of the most suitable vegetation group separations. The result obtained was supported by the determination that the species diversity in the region is higher in southern aspects compared to northern aspects.
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 Eğirdir 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.
