Berry fruit by-products are a source of polyphenol compounds and highly nutritious oils can be reused to fulfill the requirements circular economy model. One methods obtaining polyphenol-rich extracts or is extraction. Applying conventional solvent extraction techniques may insufficient reach high lipid fraction yields selectivity specific compounds. Alternative methods, mainly ultrasound-assis...

Polyphenols are naturally derived bioactive compounds with numerous reported health benefits. We have previously reported on the beneficial effect of a polyphenol-enriched apple extract in a murine model of food allergy. The objectives of the present study were to elucidate the class of bioactive polyphenols that exhibit a beneficial anti-allergic effect and to assess whether the protective eff...

Received: December 28, 2013; Revised; January 25, 2014; Accepted: March 2, 2014 . Abstract: A major problem in the micro propagation of litchi is the secretion of polyphenols into the medium by the tissues once excised. This secretion undergoes oxidation to produce substances that kill the tissues. The first visual symptom of deterioration is skin browning which has been reported to appear due ...

Supplement use among athletes is widespread, including non-traditional and biological compounds. Despite increasing research, a comprehensive and critical review on polyphenol supplementation and exercise is still lacking. This review is relevant for researchers directly involved in the topic, as well as those with a broad interest in athletic performance enhancement and sports nutrition. The p...

In recent times, there is a growing interest in nutrition and preventive health care in the development and evaluation of natural bioactive and antioxidant active products from plant materials. It is well known that polyphenol compounds are responsible for the potential antioxidant activity and radical scavenging capacity of plant foods. Consumption of a diet rich in polyphenol substances has b...

Polyphenols are a group of plant metabolites with potent antioxidant properties, which protect against various chronic diseases induced by oxidative stress. Evidence showed that dietary polyphenols have emerged as one of the prominent scientific interests due to their role in the prevention of degenerative diseases in humans. Possible health beneficial effects of polyphenols are measured based ...

The genus Streptomyces is known as producers of bioactive compounds that have antibacterial and antioxidant properties. sp. SAE4034 was to produce can inhibit kill pathogenic bacteria, including Staphylococcus aureus, but the group their inhibitory mechanisms were not yet known. ability in producing antioxidants unknown yet. This research aimed determine classification produced by SAE4034, know...

Nutrient management has increasingly become important in producing quality medicinal plant materials. Vitex negundo is an perennial widely distributed tropical Asia and Africa. This study aimed to examine the effects of nitrogen (N) phosphorus (P) fertilization on biomass, polyphenol contents, essential oil yield composition field cultivated V. negundo. Two experiments were conducted; one was p...

Dietary polyphenols come mainly from plant-based foods including fruits, vegetables, whole grains, coffee, tea, and nuts. Polyphenols may influence glycemia and type 2 diabetes (T2D) through different mechanisms, such as promoting the uptake of glucose in tissues, and therefore improving insulin sensitivity. This review aims to summarize the evidence from clinical trials and observational prosp...
