The inhibitory effect of onion extract on cassava leaf polyphenol oxidase was investigated. The polyphenol oxidase from cassava leaves was strongly inhibited by various anti-browning agents such as L-ascorbic acid and L-cysteine. The percentage of inhibition increased with the increased of anti-browning agents concentrations. The addition of heated onion extract exhibited a stronger inhibitory ...
Ultraviolet radiation divides to three bands UV-A (320-390 nm), UV-B (280-320 nm) and UV-C (254-280 nm). Different bands of ultraviolet radiation have different effects on growth, physiological and biochemical plants. In this research the effect of different bands of UV radiation on the shoot and root length, quantity of flavonoids, anthocyanine, protein, ethylene, peroxidase and polyphenol o...
Mitochondria plays a major role in maintaining homeostasis of heart cells. Mitochondria produce ATP and is the main intracellular source of reactive oxygen species (ROS) which can cause oxidative damage. Free oxygen radicals and oxidative damage are associated with cardiovascular pathology. Antioxidant defense can play an essential role in preventing oxidative damage by controlling free oxygen ...
Biosynthesis of Zinc Ferrite Nanoparticles Using Polyphenol-rich extract of Citrus aurantium flowers
This study was conducted to examine the synthesis of ZnFe2O4 nanoparticles, using the hydroethanolic extract of Citrus aurantium flowers, through the application of FeCl2.4H2O, FeCl3.6H2O, and Zinc Acetate. The present piece of work is regarded important especially when ascertaining the potential of a widely distributed underused mangrove associated plant, C. aurantium, as used in the folk medi...
partial purification and characterisation of polyphenol oxidase from tomatoes (solanum lycopersicum)
polyphenol oxidase (ppo) from tomatoes was extracted and partially purified through (nh4)2so4 precipitation, dialysis and ion exchange chromatography. the activity of polyphenol oxidase was investigated in solanum lycopersicum. spectrophotometric method was used to assay the enzyme activity and the kinetic constants - maximum enzyme velocity (vmax) and michealis - menten constant (km). of the ...

There are insufficient data to provide conclusive evidence on the health effects of most flavonoid subclasses. Future research of polyphenol bioactivity requires a more complete understanding of their intake, bioavailability and metabolism. The following summarises the limitations of polyphenol research as described across various reviews throughout the literature and presents the key requireme...
