The purpose of this study was to determine the ethnobotanical features of taxa belonging to the genus Stachys L. in Turkish Flora. Their vernacular names and local usages patterns have been determined. To determine the ethnobotanical uses of Stachys L. taxa; ethnobotanical studies made in Turkey have examined. Also, the field study carried out in different regions in Turkey. The ethnobotanical use of 38 Stachys L. taxa (29 species) has been identified in Turkey. The first 2 species that are used most: S. lavandulifolia and S. cretica. They are used 59 different of the vernacular names for Stachys L. taxa in Turkey, They are mostly known in Anatolia as "Dağ çayı". Also ""BareĢ"", ""Çaye çe"", "Rıhena tehtan" and ""Tokalı çay"" are among the names given. Stachys L. species are generally consumed as a herbal tea for medicinal in Turkey. Besides, they are used for as powder for animal disease, gargle for sore throat and handkerchief and hair accessories (both from leaves) for children. In terms of food as a spice, only the S. mardinensis species was observed. Stachys L. taxa have been revealed that they are being used in the treatment of about 40 different diseases and symptoms. Top diseases and symptoms treated with Stachys L. taxa: stomathic, cold, cough and diabetes. The most used parts of the plants are listed aerial parts and leaves.
Background: The 2019 novel coronavirus disease (COVID-19) has caused a global health catastrophe by affecting the whole human population around the globe. Unfortunately, there is no specific medication or treatment for COVID-19 currently available. Objective: It’s extremely necessary to apply effective drug treatment in order to end the pandemic period and return daily life to normal. In terms of the urgency of treatment, rather than focusing on the discovery of novel compounds, it is critical to explore the effects of existing herbal agents with proven antiviral properties on the virus. Method: Molecular docking studies were carried out with three different methods, Glide extra precision (XP) docking, Induced Fit docking (IFD), and Molecular Mechanics/Generalized Born Surface Area (MM/GBSA), to determine the potential effects of 58 phytochemicals in the content of Rosmarinus officinalis, Thymbra spicata, Satureja thymbra, and Stachys lavandulifolia plants -have antiviral and antibacterial effects- against Main Protease (Mpro) and Angiotensin Converting Enzyme 2 (ACE2) enzymes. Results: 7 compounds stand out among all molecules by showing very high binding affinities. According to our findings, the substances chlorogenic acid, rosmarinic acid, and rosmanol exhibit extremely significant binding affinities for both Mpro and ACE2 enzymes. Furthermore, it was discovered that carnosic acid and alpha-cadinol showed potential anti-Mpro activity, whereas caffeic acid and carvacrol had promising anti-ACE2 activity. Conclusion: Chlorogenic acid, rosmarinic acid, rosmanol, carnosic acid, alpha-cadinol, caffeic acid, and carvacrol compounds have been shown to be powerful anti-SARS-COV-2 agents in docking simulations against Mpro and ACE2 enzymes, as well as ADME investigations.
Bu çalışmada; Stachys L. cinsi (Lamiaceae) Distantes altseksiyonu taksonları üzerinde karşılaştırmalı anatomik ve mikromorfolojik çalışmalar yapılmış ve altseksiyonun taksonları için ayırt edici karakterler belirlenmiştir. Anatomik çalışmalarda, elle kesit alma ve parafine gömme yoluyla mikrotomda kesit alma yöntemleri kullanılmıştır. Mikromorfolojik çalışmalar ise LM (Işık Mikroskobu) ve SEM (Taramalı Elektron Mikroskobu)' de gerçekleştirilmiştir. Anatomik çalışmalarda, taksonların gövde ve yaprak yapılarında benzerlikler bulunmasının yanında bazı ayırt edici farklılıklar da tespit edilmiştir. Mikromorfolojik çalışmalarda ise taksonların tüy ve nutlet özelliklerinin tür ve tür altı seviyede kullanışlı karakterler olduğu görülmüştür. Çalışma neticesinde gövde yapısında köşelerde demet şeklinde sklerenkima varlığı, salgı tüylerinin varlığı ve tipleri, nutlet yüzey ornamentasyonu, nutletteki kanat varlığı ve karın bölgesinin yapısı taksonların ayırt edilmesinde kullanılabilecek önemli karakterlerdir. Numerik bulgulara göre tüy ve nutlet mikromorfolojik karakterlerinin anatomik karakterlerden daha önemli olduğu görülmüştür.
One of the important causes of air pollution is automobile emissions Automobile exhausts can be toxic and harmful to plants. In light of this, this study aimed to examine the anatomical and micromorphological effects of auto exhaust pollution on Pistacia vera L. (Pistachio), an important agricultural plant. Pistachio leaflet samples taken from heavy traffic areas and rural areas were compared anatomically and micromorphologically. Also, the data were statistically evaluated. As a result of the study, it was seen that there are anatomical and micromorphological differences between the plant in the rural area and the plant in the heavy traffic area in the city center where air pollution and the number of cars are high. In particular, significant differences were detected in the epidermis surface and cuticle structure, trichome cover, stomatal characteristics, as well as mesophyll width, and epidermis anticlinal outer wall width. As a result, the study revealed that the agriculturally important P. vera is affected by pollution anatomically and micromorphologically.
The Asteraceae family is the largest in the plant kingdom in the world. Gundelia is a genus that belongs to this family and is commonly referred to as the kenger name in Anatolia. Gundelia dersim is also an endemic species defined from Eastern Anatolia. In this study, anatomical, palynological and biochemical properties of G. dersim were discussed. When the anatomical structure of G. dersim was examined, it was seen that the mesophyll type, in which the midrib of the leaf was developed, was unifacial. There are too many sclerenchymatic cells in the vascular bundles. In addition, laticifer elements were seen on the stem and leaf. Also, it was observed that the pollen of the species is in echinate ornamentation and pollen grains are radial symmetrical, isopolar, tricolporate. Following biochemical analysis, pigment analysis, total carbohydrate and lipid peroxidation were performed. The chlorophyll a and chlorophyll b content of the species in both stem and leaf were analyzed, and the most chlorophyll content was found in the leaf. With this research, for the first time, a detailed anatomical investigation was conducted on the genus Gundelia, and it is a current view with the first consideration of the anatomical, palynological and biochemical aspects of G. dersim.
This study investigated the somatic chromosome numbers and morphometric properties of 11 different taxa belonging to the genus Cuscuta L., which is one of the parasitic flowering plants and causes significant economic losses on agricultural products. For this purpose, the species were examined karyologically and compared statistically. Belonging to the genus Cuscuta, C. campestris Yunck., C. hyalina Roth, C. kotschyana Boiss., C. babylonica Aucher ex Choisy, C. europaea L., C. kurdica Engelm., C. brevistyla A.Braun ex A.Rich, C. planiflora Ten., C. approximata Bab., C. lupuliformis Krock. C. palaestina Boiss. the chromosome number and morphology of the species were investigated using karyological techniques. Chromosome numbers of the species; C. kotschyana, C. babylonica, C. europaea, C. kurdica, C.planiflora 2n=14; C. campestris, C. hyalina, C. approximata, C. lupuliformis, and C. palaestina 2n=28 and C. brevistyla 2n=42 is determined. Also, the species’ chromosome number, total chromosome length, relative length, arm ratio, centromere index and centromere states, and karyotype asymmetry values were determined. Chromosome numbers of C. kotschyana and C. kurdica taxa were defined for the first time in this study. Thus, new data on the systematics of these species have been revealed.
