Si se comparan estos resultados con los obtenidos en las semillas de Capsicum annuum L. (pimiento) y en las zuecas de Cynara scolymus L. (alcachofa), se obtienen resultados similares, y que, además, contrastan con la diferentes concentraciones elementales del resto de los estadíos de las tres plantas comparadas. Esta evidencia permite concluir que la influencia unificadora de la función multiplicativa y diseminadora, sea sexual o vegetativa, es más fuerte que la diversidad biológica encontrada en los estadíos vegetativos.

Nevertheless important data are still unknown on the ecology of truffle and the environment in which it is developed. Our experience in truffle cultivation studies, following up of the mycorrization of plantations for more than 10 years without interruption, has allowed us to observe the variation of flora to the extent that truffle-beds evolve and mature, for which a study of flora in depth has begun. To achieve this aim, the species in the burnt areas of two truffle-beds of different ages in Navarra have been sampled and determined, as well as in near areas of natural production. The floristic catalogue and the characteristics of the environment in which they appear of natural form are shown and compared. All this puts in evidence that the p...

Oxidative stress is an imbalance between free radicals and antioxidants, so today, compounds capable of reducing or neutralizing free radicals are being studied for a therapeutic use. Origanum vulgare L. is a traditional medicinal plant used for a wide number of health problems due to its antimicrobial, carminative and antioxidant activities. However, when administered orally, gastrointestinal digestion can modify some of therapeutical properties. To avoid this, two different solid oral formulations have been designed for an O. vulgare extract evaluating their antioxidant behaviours in vitro and in vivo after a simulation of gastrointestinal digestion. The results showed that the divided powder has a lower antioxidant activity both in vitro and in vivo than the encapsulated extract. The quantitative difference of polyphenols found on HPLC-DAD (especially luteolin, apigenin and caffeic acid) may explain the differences in pharmacological activity. Thus, we propose that the best form to administrate O. vulgare extracts to maintain the antioxidant properties is the encapsulated form, that is, two capsules of 250 mg of a hydroalcoholic extract of O. vulgare with a minimum of 33 % of rosmarinic acid as a daily dose.

Healthier composition and lipid profile was obtained: 85 kcal/100 g, 3.6% fat, 0.6 g ALA and 0.44 g DHA per 100 g of product and ω-6/ω-3 ratio of 0.4. Technological and sensory problems were not detected in the new formulations. Besides, reformulation did not cause oxidation problems during 32 days of storage under refrigeration. The results suggest that it is possible to obtain reduced-fat Bolognatype sausages rich in ALA and DHA and stabilized with natural antioxidants, applying the appropriate technology without significant effects over the sensory quality, obtaining interesting products from a nutritional point of view. Highlights-Nutrition claims for Bologna-type meat products.-Sensory viability of healthier cooked reduced-fat meat products.-Natural antioxidants to preserve omega-3 enriched meat products.
