In this study the changes of total polyphenolics in different anatomical parts (stems, leaves, flowers and seeds) of common buckwheat (Fagopyrum esculentum Moench.) during vegetation period were analysed. The content of total polyphenolics was evaluated in growth phase I (formation of buds), phase II (at the beginning of flowering), phase III (full blossoming) and phase IV (full ripeness). In a...

Apples are one of the most popular foods around world. However, recently there has been a growing interest in preservation traditional apple varieties. This grown due to studies that suggest apples contain higher amounts polyphenolics and antioxidant activity compared commercial ones. Polyphenolics have gained much attention because their beneficial effects on human health, thus they became qua...

In this investigation, two species of Crataegus (hawthorn) were chosen because their polyphenolic constituents have recently received greater attention for the treatment of patients with severe heart disease. One-year-old plants of hawthorn (Crataegus laevigata and C. monogyna) were subjected to water-deficit (continuous water deprivation), cold (4 degrees C), flooding (immersion of roots of pl...

Polyphenolics, which are ubiquitous in plants, currently are among the most studied phytochemicals because of their perceptible chemical properties and antioxidant activity. Oak barrels and their alternatives, which are widely used in winemaking nowadays, contribute polyphenolics to wines and are thought to play crucial roles in the development of wines during aging. This study summarizes the d...

Polysaccharides, secondary metabolites and poly-phenolics are known to co-isolate with nucleic acids from plant tissues resulting in inhibition of molecular manipulations. RNA isolated from the polyphenolic-rich resurrection plant, Myrothamnus flabellifolius, was demonstrated to inhibit a standard polymerase chain reaction used as an assay despite the inclusion of the polyphenolic-binding compo...

Frozen blueberries (Vaccinium corymbosum L.) were processed into juice and concentrate, and the changes in anthocyanin pigments and polyphenolics (cinnamates, procyanidins, flavonol glycosides) were monitored. While juice yield was 83%, only 32% of the anthocyanins were recovered in single-strength juice. Flavonol, procyanidin and chlorogenic acid recoveries in juice were 35%, 43%, and 53%, res...

There is increasing evidence that plants can react to biotic aggressions with highly specific responses. However, few studies have attempted to jointly investigate whether the induction of plant defences is specific to a targeted plant tissue, plant species, herbivore identity, and defensive trait. Here we studied those factors contributing to the specificity of induced defensive responses in t...

INTRODUCTION: Flap necrosis remains a major complication of reconstructive surgery. Euterpe oleracea Mart., popularly known as “açaí,” is cultivated in the Amazon region of Brazil. It contains hydroxybenzoic acids, antioxidant polyphenolics, flavan-3-ols, and anthocyanins. Açaí exhibits anti-inflammatory action through the inhibition of cyclooxygenases 1 and 2 1 , vasodilation, inhibition of ni...

Objective: The present study was carried out to compare the quality of new and 24 months old sample of Chyawanprash from the same brand. Material and Methods: Total polyphenolics, total reducing sugar, ascorbic acid, hydroxymethyl furfural (HMF), and fibre content were measured in both the new and 24 months old sample of Chyawanprash. Results: Results obtained reveal the reduction in the percen...
