1. Antioxidant Capacity in Fruit and Vegetables -Cultivar Variation - Storage Conditions - Human Antioxidant Status
Abstract : The health-promoting effects of fruits and vegetables have been extensively discussed during the past decade since epidemiologic studies have shown relations between increased intake of fruit and vegetables and decreased incidences of several chronic diseases. It has been suggested that antioxidants are a main contributors to the observed effects, for example by acting as scavengers of free radicals. READ MORE

2. Antioxidant Activity of Bolivian Plant Secondary Metabolites
Abstract : Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. READ MORE

3. Antioxidants in Andean food and meals
Abstract : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. READ MORE

4. In vitro and in vivo oxidation of diastereomers of lignin models of arylgylcerol b-aryl ether type and heterologous expression of laccase
Abstract : Enzymic and non-enzymic oxidation of lignin models of the arylglycerol β-aryl ether type was investigated in experiments aimed at providing a better understanding of the initial phase of biological lignin degradation. Product profiles and diasteromer selectivity were determined to gain knowledge of the properties of the oxidants and pave the way for evaluation of the presence of the oxidants in ligninolytic fungal cultures.

5. Antioxidants in Bolivian Plant Foods. Antioxidant Capacity, Flavonoids and other Phenolic Compounds
Abstract : The total antioxidant capacity was measured and the major phenolic and flavonoid compounds were identified and quantified in a selection of Bolivian crops growing at different altitudes above seal level (a.s.l.). READ MORE
