Selecting plants with increased total polyphenol oxidases in the genus Trifolium
expression analysis polyphenolic enzyme protein quality Trifolium medium Trifolium pratense
2015/12/29
One of the aims in red clover (Trifolium pratense) breeding is to increase the polyphenol oxidase (PPO) activity, which may effectively reduce protein breakdown in silage and when cattle are fed by fr...
Total polyphenol and main flavonoid antioxidants in different onion (Allium cepa L.) varieties
onion red yellow and white varieties polyphenols
2015/1/20
Polyphenolic antioxidant compounds were studied in three onion varieties (red – cv. Karmen, yellow – cv. Všetana and white – cv. Ala) regarding their total content and qualitative composition of ...
Influence of cultivar and storage of chicory plants (Cichorium intybus L.) on polyphenol composition and antioxidative potential
antioxidants AOP DPPH leaves storage
2014/3/28
We determine the total polyphenol content (TPC) and antioxidative potential (AOP) in external and internal leaves of different cultivars of chicory, both before and after storage. We analysed the red ...

Purification and Characterization of Pear (Pyrus communis) Polyphenol Oxidase
Purification Characterization Polyphenol Oxidase
2010/4/20
Three isoenzymes of polyphenol oxidase (PPO) were isolated from a local pear variety (Ankara Armutu) through ammonium sulfate precipitation, dialysis and gel filtration. The sample obtained from dialy...
Polyphenol Oxidase Activity during Rooting in Cuttings of Grape (Vitis vinifera L.) Varieties
Vitis vinifera polyphenol oxidase rooting
2010/3/22
Polyphenol oxidase (PPO) activity was investigated during rooting in cuttings from three different grape cultivars (Vitis vinifera L. cvs. Muscat, Cardinal and Perlelte), and the enzyme activity and r...
Characterization of Polyphenol Oxidase from Jerusalem Artichoke (Helianthus tuberosus)
Characterization Polyphenol Oxidase Jerusalem Artichoke
2010/4/21
Polyphenol oxidases (PPO) in Jerusalem arthichoke (Helianthus tuberosus) skin and flesh were extracted and purified through (NH4)2SO4 precipitation, dialysis and gel filtration chromatography. The sam...
Non-Covalent Immobilization of Quince (Cydonia Oblonga) Polyphenol Oxidase
Bentonite polyphenol oxidase purification non-covalent immobilization characterization
2010/4/22
A partially purified polyphenol oxidase from quince (Cydonia oblonga) was immobilized on bentonite by simple adsorption at pH 6.8. The properties of the immobilized enzyme were compared to those of th...
Partially Purification and Characterization of Polyphenol Oxidase of Quince
Quince polyphenoloxidase purification characterization
2010/4/22
Polyphenol oxidase (PPO, EC 1.14.18.1) was extracted from quince (Cydonia oblonga) by using 0.1 M phosphate buffer, pH 6.8. The polyphenol oxidase of quince was partially purified by (NH4)2SO4 and dia...
Incorporation of EDTA for the Elimination of Metal Inhibitory Effects in an Amperometric Biosensor Based on Mushroom Tissue Polyphenol Oxidase
Incorporation of EDTA the Elimination of Metal Inhibitory Effects an Amperometric Biosensor Based Mushroom Tissue Polyphenol Oxidase
2010/6/27
Enzyme based biosensors are highly selective devices which rely on the specific binding of the target analyte (the substrate) to the active-site regions of the enzyme. The enzymatic reaction between m...
