ÜlkemizdePolygonumtürleri ile yapılan çalışmalar daha çok, Türkiye’de madımak olarak bilinenPolygonum cognatumMeissn. bitkisi üzerinedir1.Bu çalışmada ise endemikPolygonum sivasicumKit Tan &Yıldız(Sivas madımağı) türünün toprak üstü kısmından farklı ekstraksiyon yöntemleriyle elde edilen ekstrelerin antioksidan aktiviteleri metal bağlama ve CUPRAC yöntemleri, antiradikal aktiviteleri ise DPPH serbest radikal giderimi ve ABTS katyon radikali giderimi yöntemleriyle belirlendi.Diyetimizin bir parçası olarak, polifenoller birçok sağlık faydası ile bağırsakta sindirim sürecinden geçerek sindirim yoluyla dolaşıma katılmaktadır.Diyet polifenollerinin, insanlarda mide sağlığı açısından etkilerini anlamak için bu bileşenlerinin vitrobiyoerişilebilirlik çalışması ağız, mide ve bağırsakda sindirime uğratıldı. Sindirim öncesi ve sonrası fenolik bileşik profili LC-MS ile belirlendi, 27 bileşiğin tanımlandığı analizde rutin, hiperosit ve klorojenik asit majör fenolik bileşikler olarak belirlendi.

- PublicationMetadata onlyAntibiofilm formation, antioxidant and anticholinesterase activities of essential oil and methanol extract of Marrubium deserti de Noé(2016-01-01T00:00:00Z) Chemsa, Ahmed Elkhalifa; Zellagui, Amar; Öztürk, Mehmet; EROL, EBRU; Ceylan, Ozgür; Duru, Mehmet Emin; Gherraf, Noureddine; EROL, EBRUThe essential oil obtained from the aerial parts of Marrubium deserti de Noé. (Lamiaceae), growing in the North fringe of the Algerian Sahara, was analyzed by GC-MS. Thirty-eight compounds were identified, representing 99.70% of the total oils. The GC-MS analysis revealed the presence of tetracosane, germacrene D, Δ-cadinene, a-cadinol and t-cadinol as the main constituents, representing 31.11%, 7.91%, 6.52%, 6.26% and 5.81%, respectively. Minimum inhibitory concentrations (MICs) of essential oil and methanol extract were calculated by microtitre broth dilution method, and antibiofilm effects by microplate biofilm assay. The highest antibiofilm activity was found to be 69.31% against Micrococcus luteus NRRL B-4375 at 25 mg/mL for methanol extract and 36.62% against Candida albicans ATCC 10239 at 25 μL/mL concentration for essential oil. The antioxidant activity was determined using three complementary tests namely: β-carotene-linoleic acid, DPPHfree radical scavenging, and CUPRAC assays. In β-carotene-linoleic acid assay, both the oil and the extract exhibited good lipid peroxidation inhibition activity, demonstrating 76.81 ± 0.59 and 86.33 ± 0.27% at 200 μg/mL concentration, respectively. In DPPH and CUPRAC assays, however, the methanol extract exhibited high antioxidant activity; however, the essential oil showed weak activity. The in vitro anticholinesterase activity, was carried out against acetylcholinesterase and butyrylcholinesterase enzymes spectrophotometrically using Elman method. Methanol extract showed weak acetylcholinesterase and butyrylcholinesterase inhibitory activities, while the essential oil was inactive against both enzymes.

Leaves and fruits can be prepared as food flavorings, juices, and teas. Phytochemical analysis of these species has reported alkaloids, tannins, phenolic compounds and oleanolic acid, among others. Moreover, p-cymene, limonene and ocimene as major compounds in essential oils were found by gas chromatography. Berberis is an important group of the plants having enormous potential in the food and pharmaceutical industry, since they possess several properties, including antioxidant, antimicrobial, anticancer activities. Here we would like to review the biological properties of the phytoconstituents of this genus. We emphasize the cultivation control in order to obtain the main bioactive compounds, the antioxidant and antimicrobial properties in order to apply them for food preservation and for treating several diseases, such as cancer, diabetes or Alzheimer. However, further study is needed to confirm the biological efficacy as well as, the toxicity.
