  Antigenotoxic Effects of Stachys viscosa (Lamiaceae), a potential medicinal plant in Drosophila melanogaster

  Karabulut, Aygul Kilic; Açar, Mikail

  This research aimed to examine the anti-genotoxic properties of Stachys viscosa, a plant of the Lamiaceae family, which has medicinal and aromatic properties and is widely used in cosmetics, food, and pharmaceutical industries. The Drosophila wing somatic mutation and recombination test (SMART), an in vivo tool for evaluating somatic mutation and recombination, was employed. The antigenotoxic effect of the S. viscosa plant against mitomycin C (MMC) mutagen was investigated. The study evaluated doses of 5 mg, 15 mg, 45 mg, and 60 mg of S. viscosa, concluding that doses of 45 mg and 60 mg effectively mitigated DNA damage induced by MMC. At doses of 45 mg and 65 mg, the total number of spots caused by MMC was suppressed by 8.21% and 13.17%, respectively. The data collected indicate that the S. viscosa plant possesses certain anti-genotoxic properties.

  Yilmaz, Fatih; Türkoglu, Ismail; Kirmizikaya Özmen, Gorkem; Yüce Babacan, Ebru; Yilmaz, Okkes

  13 species of Gundelia species plants are endemic in T & uuml;rkiye and are frequently used by the public for both nutrition and medicinal objectives. In this study, three parts (flower, leaf, and stem) of three species of Gundelia ( G.dersim , G.glabra, and G.munzurensis) were biochemically investigated. DPPH and ABTS analyses for antioxidant activity were performed on methanol extracts of plant parts. As a result of both analyses in parallel, the flower part of G.munzurensis had the highest %Inhibition value (DPPH:91.85 +/- 0.78; ABTS:97.38 +/- 0) (P<0.001). In total phenolic (29.09 mg GAE/g) and total flavonoid (5.59 mg CE/g) measurements, the highest amount was found statistically quite significant (P<0.001) in the leaf part of G.munzurensis. Gallic, vanillic, ferulic, romantic, and cinnamic acids, which are phenolic acids and of the flavonoids, rutin, catechin, naringin, and naringenin, were determined in all plant parts. Vitamin D3, alpha-tocopherol, ergosterol, stigmasterol, and beta-sterol were detected in parts of all plant species. While palmitic (16:0), palmitoleic (16:1), stearic (18:0), oleic (18:1), linoleic (18:2), and linolenic (18:3) fatty acids as the main fatty acids were detected in all parts of the three Gundelia species, lauric (12:0), tridecanoic (13:0), myristic (14:0), pentadecanoic (15:0), cis-10-pentadecanoic (15:1), heptadecanoic (17:0), cis-10heptadecanoic (17:1), and eicosanoid (21:0) acids were also identified at different concentrations. Considering the biochemical properties of Gundelia species, it shows that they can be consumed as food and also used pharmacologically.

  Acar, Mikail; Tasar, Neslihan; Akbulut, Guelcin Beker

  In this study, the anatomical and micromorphological structure, karyological characteristics and biochemical content of Scutellaria orientalis subsp. virens and endemic Scutellaria salviifolia, whose distributions areas overlap, were compared. Some anatomical and micromorphological differences were observed on the taxa; scleranchymatic pericycle layer on the stem, stomata density, distribution of trichomes, as well as the main vascular bundle and general shape of the petiole. The chromosome numbers of both taxa were determined as 2n = 22. However, there was a difference between chromosome length range and total chromosome length. The chromosome numbers and chromosome morphologies of these species have been defined for the first time in this paper. Differences in biochemical content were observed between species. Chlorophyll a (Chl a), total chlorophyll (Total Chl), total carbohydrate and malondialdehyde (MDA) contents were determined higher in leaf and stem samples of S. orientalis subsp. virens than S. salviifolia. There was no significant difference between the two taxa in terms of chlorophyll b (Chl b) content. Carotenoid (Car) content was detected higher in leaves samples of S. orientalis subsp. virens, but no significant difference was found between stems samples. Also, the effect of taxa on biochemical contents in relation to the habitat they live in is given in this study.

  Açar, Mikail; Satil, Fatih

  In this study; comparative anatomical and micromorphological studies were performed on the subsection Distantes of the Stachys L. genus (Lamiaceae). Also, it was determined distinctive anatomical characters for the taxa of subsection in the study. In anatomical studies, free-hand cross-sections and the paraffin embedding method was applied with the microtome. Micromorphological studies were performed in LM (Light Microscope) and SEM (Scanning Electron Microscope). In anatomical studies, besides of similarities in stem and leaf structures there were also some differences in taxa. In micromorphological studies, the trichome and nutlet characteristics were found to be useful characters on taxa and at species and subspecies level. As a result of the study, the presence of sclerenchyma like a bundle in the stem structure and the presence and types of glandular trichomes and ornamentation on the surface of nutlet, the presence of the wing and ventral structure in the nutlet were important characters that can be used to distinguish taxa. According to the numerical findings, trichome and nutlet micromorphological characters were more important than anatomical characters.
