Medicinal plants reveal their therapeutic effects due to the high amount of phenolic compounds confined abundantly in roots, fruits, leaves, and flowers. Rosa heckeliana Tratt, as a member of Rosa, was recently discovered as one of the important medicinal plants used in folk medicine. In this study, the therapeutically notable Rosa heckeliana was selected for the analysis of important phenolic components particularly confined in the roots. The roots were first extracted in methanol, then phenolic constituents were partitioned according to polarity by fractionation method. The method was also supported by the total amount of phenolic compounds. The highest total phenolic content as gallic acid equivalent (8.8 +/- 0.19 mu g/mg) was obtained in the ethyl acetate fraction. Hence, that fraction was further analyzed for the identification of phenolic constituents by employing high performance liquid chromatography equipped with diode array and fluorescence detectors. Structural information on the compounds was confirmed by high-resolution mass spectrometry. Accordingly, catechin, caffeic acid, epicatechin, p-coumaric acid, scopoletin, ellagic acid, and quercetin were identified in the ethyl acetate fraction. Catechin, epicatechin, and scopoletin revealed fluorescent characteristics. To the best of our knowledge, this is the first detailed effort for the fractionated analysis of phenolic constituents in the roots of Rosa heckeliana.

Characterization of humic materials extracted from hazelnut husk and hazelnut husk amended soils Cimen, Funda; Ok, Sonay Sozudogru; Kayran, Ceyhan; Demirci, Şahinde; Ozenc, Damla Bender; Ozenc, Nedim (Springer Science and Business Media LLC, 2007-06-01) This study was carried out to determine effects of composted hazelnut husk (CHH) on some chemical properties of soil and soil humic acid (HA). Compost application increases organic matter (OM) content of the soil considerably, OM value of 3.18% became 3.89% in 3 years time interval. Before application of compost, the soil pH was found to be 5.37, while after compost application it became 5.61. FTIR characteristics of humic acid/humic acid-like materials extracted from the original hazelnut husk, composted h...
Isolation of a bioactive compound hypericin from a medicinal plant hypericum perforatum L. using basic chromatography methods Duru, Betül; Çoruh, Nursen; Department of Chemistry (2003) Medicinal plants which have been widely used in folk medicine are known to contain important biologically active compounds. Most of today̕s synthetic drug raw materials are to be prepared by using plant originated compounds as the starting material. Hypericum Perforatum is one of the medicinal plants that grows in Europe, Western Asia and Northern Africa and is distinguished by its golden yellow flowers. The common name of the plant is St. John̕s wort. From the time of the ancient Greeks down through the mi...
Identification and characterization of hydrolytic enzymes from the midgut of Sunn Pest of wheat (Eurygaster integriceps) Ogur, E.; YÜCEL, MUSTAFA; Öktem, Hüseyin Avni (Informa UK Limited, 2009-01-01) To help in the development of Sunn Pest-resistant transgenic plants employing protease or alpha-amylase inhibitors, midgut hydrolytic enzymes of Sunn Pest (Eurygaster integriceps, Put.) (Heteroptera: Scutelleridae) were identified and characterized biochemically. We observed levels of very low proteolytic activity of trypsin (3 nmoles/min/mg), elastase (0.66 nmoles/min/mg) and leucine aminopeptidase-like (14.4 nmoles/min/mg) proteases, but no chymotrypsin and papain-like activity. Proteolytic activities wer...
Formulation and characterization of clove and thyme oil emulsions Tonyalı Karslı, Gökcem; Öztop, Halil Mecit; Şahin, Serpil; Department of Food Engineering (2021-2-10) Essential oils are natural aromatic compounds obtained from various parts of plants such as flowers, bark, stems, and roots. They have been used in medicine, cosmetics, and food science since ancient times due to their antimicrobial, antioxidant, and therapeutic properties. Especially in recent times, negative impressions about synthetic additives have increased the use of essential oils in the food industry. The aim of this study is to produce and characterize emulsions with thyme and clove essential oils ...
Examination of interfacial properties of quince seed extract on a sunflower oil-water interface Kirtil, Emrah; Kurtkaya, Enis; Svitova, Tatyana; Radke, Clayton J.; Öztop, Halil Mecit; Şahin, Serpil (2021-12-14) Seeds of the plant quince are a natural hydrocolloid source whose extract has shown promising results in stabilizing emulsions. The study aims to discover how quince seed extract's interfacial properties (dynamic surface tension and dilatational surface rheology) on an oil–water interface change with varying concentrations (between 0.01% and 1%), pH's (3, 7, and 11), and ionic strengths (0.1, 0.3, 0.5 M NaCl). The lowest concentration that yielded a statistically significant drop in interfacial was found as...
