Botanical origin of the nectar predominantly affects the chemical composition of honey. Analytical techniques used for reliable honey authentication are mostly time consuming and expensive. Additionally, they cannot provide 100% efficiency in accurate authentication. Therefore, alternatives for the determination of floral origin of honey need to be developed. This study aims to discriminate characteristic Anatolian honey samples from different botanical origins based on the differences in their molecular content, rather than giving numerical information about the constituents of samples. Another scope of the study is to differentiate inauthentic honey samples from the natural ones precisely. All samples were tested via unsupervised pattern recognition procedures like hierarchical clustering and Principal Component Analysis (PCA). Discrimination of sample groups was achieved successfully with hierarchical clustering over the spectral range of 1800-750 cm(-1) which suggests a good predictive capability of Fourier Transform Infrared (FTIR) spectroscopy and chemometry for the determination of honey floral source.

Effect of processing on buckwheat phenolics and antioxidant activity Şensoy, İlkay; Ho, Chi-Tang; Karwe, Mukund V. (Elsevier BV, 2006-01-01) The effect of processing on functional compounds in buckwheat was investigated. Extractions of buckwheat flour were carried out before and after roasting or extrusion. Folin-Ciocalteu assays indicated that processing did not cause any change in total phenolic content in buckwheat flour. Roasted (200 degrees C, 10 min) dark buckwheat flour exhibited an increase in non-polar compounds as well as polar compounds whereas extrusion exhibited increase only in polar compounds. Antioxidant activity test (DPPH) show...
Determination of silver by chemical vapour generation and atomic absoption spectrometry Öztürk, Çağla Pınar; Ataman, Osman Yavuz; Department of Chemistry (2004) A method for determination of silver has been developed based on chemical vapour generation atomic absorption spectrometry (CVGAAS). Volatile species of silver in acidified medium were generated by the reduction of sodium tetrahydroborate; these species were sent to a flame-heated quartz tube atomizer (QTA) following isolation by using a gas-liquid separator. Flow injection (FI) was used for sample introduction. Optimization of parameters such as; concentrations of acid and NaBH4 concentration, flow rates o...
Survey of 55 Turkish Salvia taxa for their acetylcholinesterase inhibitory and antioxidant activities ŞENOL, FATMA SEZER; ERDOĞAN ORHAN, İLKAY; Celep, Ferhat; Kahraman, Ahmet; Doğan, Musa; Yilmaz, Guelderen; ŞENER, BİLGE (Elsevier BV, 2010-05-01) In the current work, our target was to screen inhibitory potentials of 55 Turkish Salvia taxa, 28 of which are endemic, against acetylcholinesterase (AChE), which is a chief enzyme in pathogenesis of Alzheimer's disease (AD). The dichloromethane, ethyl acetate, and methanol extracts prepared from 55 Salvia taxa were tested for their AChE inhibitory activity at 25, 50, and 100 mu g/ml using an ELISA microplate reader. The extracts were also screened for their scavenging effect against DPPH radical and iron-c...
Antioxidant capacities of Gundelia tournefortii L. extracts and inhibition on glutathione-S-transferase activity Çoruh, Nursen; Ozgokce, F.; Iscan, M. (Elsevier BV, 2007-01-01) Gundelia tournefortii L. is an important food source and a well-known medicinal plant in Eastern Anatolia. Therapeutic effects of medicinal plants are known to be closely related to their antioxidant capacities. Antioxidant activities of G. tournefortii, both for the aerial parts and seeds, were investigated by using both 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and lipid peroxidation inhibition methods. The seeds were found to have higher antioxidant potential than the aerial, with IC50 valu...
Immunization of the industrial fermentation starter culture strain of Saccharomyces cerevisiae to a contaminating killer toxin-producing Candida tropicalis Izgu, F; Altinbay, D; Derinel, Y (Elsevier BV, 2004-12-01) K3 killer trait was introduced into the fermentation starter strain of Saccharomyces cerevisiae BSP 1 in order to construct immune industrial strain that produces K3 type killer toxin and was resistant to Candida tropicalis (K+) contamination. Protoplasts of respiration-deficient Rhodegrees strain of S. cerevisiae NCYC 761 (K3) and S. cerevisiae BSP 1 were fused. The resulting respiration-competent hybrid with K3 type killer activity was selected on media containing a non-fermentable carbon source and by a ...
