Xanthine oxidase plays crucial roles in the production of reactive oxygen species (ROS), and uric acid in blood which may lead to gout, one of the oldest known forms of arthritis amongst humans. Summer savory (Satureja hortensis L.) a medicinal/spice exhibits antioxidant activity, but unknown effects on xanthine oxidase activity. Here, for the first time, we examined the effects of S. hortensis...

Absorption and reflectance spectra of maple (Acer platanoides), cotoneaster (Cotoneaster alaunica), dogwood (Cornus alba) and pelargonium (Pelargonium zonale) leaves with a wide range of pigment content and composition were studied in visible and near-infrared spectra in order to reveal specific anthocyanin (Anth) spectral features in leaves. Comparing absorption spectra of Anth-containing and ...

This is the first report to identify the presence of chicoric acid (cichoric acid; also known as dicaffeoyltartaric acid, which is a caffeic acid derivatizedwith tartaric acid) in basil leaves. Rosmarinic acid, chicoric acid and caftaric acid (in the order of most abundant to least; all derivatives of caffeic acid) were identified in fresh basil leaves. Rosmarinic acid was themain phenolic comp...

Precision monitoring of plant health via remote sensing benefits from accurate quantification of attributes such as foliar pigments related to stress. For example, pigment content (the ratio of chlorophyll to carotenoids) can be indirectly related to photosynthetic efficiency in plants and hence productivity. Optical remote sensing can potentially provide this data with high spatial accuracy vi...

Purple heading Chinese cabbage has become popular in recent years due to its attractive color and health benefits. However, purple varieties remain rare, the regulation mechanism of anthocyanin accumulation is still largely unknown. By introducing trait from Brassica juncea, a new cultivar (18M-245) was generated with deep leaves at both seedling adult stages. Anthocyanin 18M-245 increased when...

In this study, purple basil leaves were dried in 3 different methods (oven, microwave, and shade drying) then infused 5 times hot water at 90 oC. Analyses of total phenolic content, antioxidant activity, monomeric anthocyanin color parameters performed on tea samples. When the analysis results evaluated, best determined samples prepared from oven shade, brewing 10 15 minutes. 45 minutes was inf...

to evaluate the effect of chemical and bio-fertilizer on nitrogen, phosphorus and potash concentration, biochemical traits and calyxes yield of roselle, an experiment was conducted in the split plot based on randomized coplete block design with three replications, at the research station in zabol university, during 2013 and 2014. the main plot consisted of three levels: phosphorus, nitrogen and...

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used an electron donor to TiO2 nanoparticles and electrolyte transport medium. One of the extracts purple spinach moringa leaves photosensitizer chlorophyll extract or anthocyanin. The nature able absorb light function in DSSC. Making Moringa leaf red after being blended, dried ground into powder. Then powder was mixed ...

Anthocyanins are flavonoid compounds that protect plant tissues from many environmental stresses including high light irradiance, freezing temperatures, and pathogen infection. Regulation of anthocyanin biosynthesis is intimately associated with environmental changes to enhance plant survival under stressful environmental conditions. Various factors, such as UV, visible light, cold, osmotic str...
