ISANH Polyphenols 2014 Distinguished Speakers


Dr Fred Stevens, from Linus Pauling Institute and College of Pharmacy, Oregon State University, Corvallis, Oregon, U.S.A will present his recent studies about Global metabolomics for discovery of polyphenol bioactivity: unravelling broad-spectrum effects of xanthohumol in a rodent model of obesity during Lisbon Polyphenols World Congress.

Xanthohumol is a prenylated flavonoid found in hops and beer, and in dietary supplements.

The team treated Zucker fa/fa rats, a model of obesity and metabolic syndrome, for six weeks with xanthohumol at four dose levels and measured metabolome profiles in addition to single endpoints of glucose and lipid homeostasis.


Saura Calixto

Dr Fulgencio Saura-Calixto, from ICTAN-CSIC, Madrid, Spain will give an overview of recent advances & perspectives of non-extractable polyphenols and macroantioxidants during the 8th World Congress on Polyphenols Applications 2014.

Non-extractable polyphenols (NEPP) or macroantioxidants are a new type of antioxidants bioavailable in the large intestine where they exhibit a significant antioxidant activity and produce absorbable metabolites after the action of the microbiota. They are plant food constituents that contribute significantly to the total PP intake in the diet.


Perez-JimenezDuring Lisbon Polyphenols 2014, as special session will be dedicated to Pomegranate Polyphenols: Recent Advances & Perspectives.

One of the presentation will be done by Dr Jara Perez-Jimenez, from ICTAN, Spain about "Regular consumption of a pomegrante and grape juice improves oxidative status and causes metabolome changes in healthy adults". This study was elaborated by Dr Maria Elena Diaz Rubio from ICTAN, Spain.



Fruit and vegetable by-products are today considered as a cheap source of valuable components, as since the existent technologies allow the recovery of target compounds and their recycling inside food chain as functional additives in different products. Polyphenols, phenolics acids, antioxidants found in huge amount in bio-waste and by-products, can be used in health and food industries.



Frau Richling f 02 03Pr. Elke Richling from Kaiserslautern Technical University, Germany will talk about Encapsulation modulates the bioavailability of anthocyanins and their degradation products during Polyphenols 2014 World Congress in Lisbon next June 2014.

Anthocyanins are responsible for attractive color of red fruits and are attributed with beneficial effects. Especially bilberries have a broad spectrum of anthocyanins. For the described biological mechanisms, the bioavailability of anthocyanins at the site of absorption has a crucial importance.
