Either NO(3) (-) (16 millimolar) or NH(4) (+) (1 millimolar) completely inhibited infection and nodulation of white clover seedlings (Trifoliin repens) inoculated with Rhizobium trifolii. The binding of R. trifolii to root hairs and the immunologically detectable levels of the plant lectin, trifoliin, on the root hair surface had parallel declining slopes as the concentration of either NO(3) (-...

Strawberries purées are incorporated in foods and subjected to pH modulation according to the expected final food matrix. The effect of pH on strawberry polyphenols stored at 4 and 23 °C for 90 days was evaluated. Total antioxidant activity and total phenolics content were only affected by time according to a first order model. The pH 4.5 induced higher decrease in (-)-epigallocatechin gallate ...

The discovery of a green extraction solvent for natural plants could promote related research. In this study, deep eutectic solvents (DES) were used as coupled with an ultrasound-assisted method (UAE) to extract flavonoids from lotus leaves. Thirty-four different DES performed and choline chloride/urea 40% water was chosen the most promising one, parameters in procedures optimized, resulting hi...

Antennaria dioica ( Asteraceae family) – is a perennial herb, commonly found in dry grasslands and sandy or stony places from Eurasian areas. It known traditional medicine as antioxidant, diuretic, choleretic anti-inflammatory remedy. This species should be reconsidered possible sources of phenols, mainly flavonoids hydroxycinnamic acids. Thus, the aim this study was to validate chromatographic...

The dynamic changes in phenolic composition and antioxidant activity, the potential effect on foam cell formation cholesterol efflux during noni (Morinda citrifolia Linn.) fruit juice fermentation were investigated this study. of compounds was significantly different at various times. Rutin, quercetin, isoquercitrin major phenolics fermented based a quantitative analysis representative phenolic...

Abstract Mulberry ( Morus alba L.) leaf, a “source of both medicine and food”, contains antioxidant ingredients such as flavonoids, alkaloids polyphenols. The effects 6-benzylaminopurine (6-BA) treatment on plant growth flavonoid contents in mulberry leaves were investigated this study. expression rutin (Rut), chlorogenic acid (ChA), isoquercitrin (IQ) astragaloside IV (Ast) related genes the s...
