چکیده

The analyze of an increasing number of plants, and through this one the discovery of new organic molecules of vegetable nature introduced, in the profile industry, new molecular structures, pharmacologically active, that serve as a large perspective base for the future therapy, each isolated molecular structure from plant serving, in its turn, to obtain new derivate biologically active. The forest fruits represent a particular importance in phytotherapy, especially due to exceptional nu-tritive qualities, these ones containing numerous basics which present bioactive properties, including even a remarkable antioxidant activity, put on the account of the ascorbic acid presence, of pro-vitamins A, of vitamin E, of flavonoid and of other phenolic compounds (1). The fruits have energetic and plastic role due to their contribution in various substances needful for the organism, mostly in what concerns the deploy of different biologic processes through the enzymatic substances, the hormonal substances, the vitamins and the microelements contained in, contributing at the rational alimentation of the human being. There were taken in study a number of five species from spontaneous fauna namely Vaccinium myrtillus, Ribes rubrum, R. nigrum, Hyppophae rham-noides and Rosa canina harvested from the Suceava County's territory, Romania, in Aug-Sep 2014 period , in the fruits' pulp being determined the content of vitamin C and provitamin A. Taken into account that the sun exposure and, respectively the shading degree of bushes were different, it had been recourse to prelevation of biologic material from several exemplars with the aim of obtaining a reproductibility degree higher as possible of experimental results, the values systematized in Fig 1 and 2 representing, for each active principle in part, the average of these repetitions. Ascorbic acid content assay was affected using method with potassium ferricyanide and the caro-tenes through colorimetric method, using like liquid of compensation the ether of petroleum (2). The forest fruits analyzed by us are sources very reach in vitamin C, which they maintain in stable condition (due to antocians) and in biologic active condition, because they don't contain the ascorbat-oxidase enzyme, which inactivate the vitamin C, transforming this one in dehi-droascorbic acid. Thus, the highest content of ascorbic acid it is found in the case of Hyppophae rhamnoides species (369.2 ± 7.651 mg/100 g bio-logic material), followed by R. nigrum (294.4 ± 16.809 mg/100 g biologic material and Rosa cani-na (273.38 ± 28.077 mg/100 g biologic material), while the red currant presents a medium contain …

Avocado Consumption Enhances Human Postprandial Provitamin A Absorption and Conversion from a Novel High–β-Carotene Tomato Sauce and from Carrots12

Dietary lipids have been shown to increase bioavailability of provitamin A carotenoids from a single meal, but the effects of dietary lipids on conversion to vitamin A during absorption are essentially unknown. Based on previous animal studies, we hypothesized that the consumption of provitamin A carotenoids with dietary lipid would enhance conversion to vitamin A during absorption compared wit...
