Öğe Anatomy, trichome micromorphology and phytochemical profile of Stachys rizeensis R.Bhattacharjee from Turkey(Elsevier, 2022) Gercek, Yusuf Can; Sahin, Aydan Acar; Bayram, Nesrin Ecem; Celik, Saffet; Sefali, Abdurrahman; Gidik, Betul; Oz, Gul CevahirIn recent years, the popularity of natural products and natural product formulations has increased due to their beneficial effects on health. As a part of this trend, Lamiaceae family members have attracted attention due to their rich bioactive properties. Although the Stachys rizeensis R.Bhattacharjee plant is an endemic plant species in Turkey, no studies focus on its characterization. Hence, the present study aims to demonstrate the anatomical, morphological and phytochemical characterization of S. rizeensis in Turkey. In the first stage of the study, anatomical and trichome morphological characterization was performed to contribute to the taxonomic definition of S. rizeensis was found to be anatomically different from some other previously studied Stachys sp. by showing lacunar collenchyma type, uncertain cambium at the corners, two or three rows of endodermis in certain areas in the stem and two rows of palisade parenchyma, capitate and peltate glandular trichomes in the leaf. In the second stage, the phenolic profile, total phenolic/flavonoid content and antioxidant activity of the plant extracts prepared using solvents with different polarities (ethanol, methanol, water, ethyl acetate and hexane) were tested to determine the phytochemical content of the plant. The phytochem-ical analysis supported by chemometric analysis (PCA and HCA) revealed that methanol was the most efficient organic solvent for the extraction of the phytochemical compounds of the plant. Additionally, it was observed that chlorogenic acid (1842.40-217,086.19 mg/kg), verbascoside (2591.43-204,429.81 mg/kg), luteolin (3579.56-88,636.14 mg/kg) and kaempferol (9706.30-50,340.93 mg/kg) compounds were present at maximum levels in this plant, in which 31 different phenolic compounds were scanned using LC-MS/MS. In addition, results obtained from the phytochemical analysis revealed that S. rizeensis is a valuable plant that can be used for medical protection/treatment and that it could also have a variety of culinary applica-tions. The present study served as the first original report regarding the chemical profile and anatomical characteristics of S. rizeensis (Lamiaceae) from Turkey. (C) 2022 SAAB. Published by Elsevier B.V.

The aim of this study is to reveal for the first time the biological activities of this plant and evaluate its potential use as a natural product. For this reason, different extracts (ethanol, methanol, ethyl acetate, and hexane) of the plant's aerial parts were used in determining the antioxidant (2,20-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid and 1,1-diphenyl-2-picrylhydrazyl assays), antimicrobial (disc diffusion and microdilution methods), and enzyme inhibition activity (calorimetric methods) related to diabetes (alpha-amylase and alpha-glucosidase). Moreover, the phenolic constituents were analysed by high performance liquid chromatography. Methanol extract of the plant exhibited significant biological activity compared to other extracts. This extract had the highest amount of chlorogenic acid as phenolic compound. In addition, all extracts showed inhibition against at least one test microorganism. According to the results, P. appendicigerus has the potential to be used as a natural antioxidant, antimicrobial and enzyme inhibitor.Öğe Contributions on the southern distribution of Vespertilio murinus Linnaeus, 1758 (Chiroptera: Vespertilionidae) from Turkiye(Tubitak Scientific & Technological Research Council Turkey, 2022) Karatas, Ahmet; Bulut, Safak; Sefali, Abdurrahman; Toprak, Ferhat; Sahin, Mehmet Kursat; Ozkurt, Sakir OnderVespertilio murinus Linnaeus, 1758, has a wide distribution from France to Japan, and from Iran in the south to Scandinavia and Russia in the north. The only records of the parti-coloured bat, Vespertilio murinus known from Turkey so far were based on subfossils, remains from owl pellets, and ultrasound recordings. We present the first records of live individuals from two Turkish provinces, Ardahan and Bayburt. Additionally, based on echolocation call records, its known distribution in the Anatolian Peninsula was proved to be wider. The global distribution of the species has been mapped by using ecological niche modelling. The results revealed that its distribution is highly influenced by precipitation dynamics. Although no cases of domestic cat predation on bats have previously been documented in Turkey, this paper also provides the first case study of V. murinus predated by a domestic cat in Ardahan, in November 2003.Öğe DETERMINATION OF ANTIOXIDANT, ANTIMICROBIAL ACTIVITIES, PHENOLIC COMPOUNDS OF WILD ROSA L. SPECIES BAYBURT, TURKEY(Parlar Scientific Publications (P S P), 2019) Gidik, Betul; Akar, Zeynep; Can, Zehra; Sefali, Abdurrahman; Erturk, OmerFive different rosehip (Rosa L.) species including, Rosa canina, Rosa iberica Stev, Rosa villosa, Rosa beggeriana Schrenk and same kind of but different location Rosa spinosissima grown in Bayburt from Turkey are studied. The wild species of Rosa L. were collected from Rocks and Steps, Field and garden borders. Morphological parameters were measured as fruit and seed weights and fruit and seed size. Ten fruits were chosen randomly for the measurement and take the average of them to determine the weights and size. In our study was determined antioxidant activity, antimicrobial activity and phenolic compounds. As antioxidant activity; total phenolic total flavonoid, condense tannin contents, CUPRAC, FRAP, ABTS. Nineteen standard of phenolic compositions of fruits and seeds were determined. Antioxidant, antimicrobial activities of the extracts were found high levels in rose hip species fruit than seed. Catechin, rutin protocatequic acid and CAPE were principal for all rose hip species fruit but, was not deteceted CAPE Kop Mountain, Yukari Kop Village Rosa spinosissima species. This suggests that the difference in location affects the phenolic content. Pearson Correlation analyze has done with the morphological parameters, GPS data, antioxidant activity and phenolic compounds by using the SPSS software programme version 25.0.Öğe Fruit and seed macro- and micromorphologies of the genus Matthiola (Brassicaceae) in Turkey and their taxonomic value(Tubitak Scientific & Technological Research Council Turkey, 2019) Kaya, Ayla; Unal, Murat; Sefali, Abdurrahman; Martin, EsraMacro- and micromorphological features of fruit and seeds belonging to 12 taxa genera of Matthiola W.T. Aiton were studied via stereomicroscope and scanning electron microscope. In macromorphological studies, the following variables were investigated: the shape, size, and color of fruit and seeds; the length of fruiting pedicel; the structure of the median vein; stigma (horns); and trichome properties and density in fruit. In micromorphological studies, the presence or absence of seed wings, seed coat pattern in disc and wing, and epidermal cell shape in disc and wing were determined. According to our findings, all characters of fruit and seeds are extremely variable and can be used as criteria to distinguish species of the genus.Öğe Pastinaca vanensis (Apiaceae), a new species from Turkey(Magnolia Press, 2022) Demir, Ibrahim; Sefali, Abdurrahman; Yapar, YakupPastinaca vanensis is described as a new species from the Ba??kale district (Van-Turkey).
