Abstract: Selenium (Se) is an essential trace element to animals and humans as Se is incorporated in a series of organic molecules, such as 30 mammalian selenoproteins or seleno-enzymes, which are vital for the basic functions of life. To increase the Se intake in Se-deficient areas, food and feed can be enriched using Se fertilizers or supplements. The aim of this study is to investigate the distribution, speciation, bioaccessibility, and bioavailability of Se in Se-enriched wheat (SW) grain and in Se-enriched chicken meat products using commercial enzymes and human gastric juices (HGJs). Results from the present work show that Se in wheat is bioaccessible and bioavailable, and that SW flour or bran can serve as a valuable dietary source of Se to humans. However, the bioaccessibility studies using commercial enzymes and HGJs for wheat flour, bran, and chicken meat digestion suggests that the use of commercial enzymes overestimate Se bioavailability. Furthermore, the use of NaCl or Tris-HCl to extract Se proteins from enriched products was not suited for bioaccessibility studies.The SW flour or bran can, however, serve as a valuable dietary source of Se to humans.

Roseroot, Rhodiola rosea, is a perennial herbaceous plant of the family Crassulaceae. The rhizomes of 95 roseroot clones in the Norwegian germplasm collection were analysed and quantified for their content of the bioactive compounds rosavin, salidroside, rosin, cinnamyl alcohol and tyrosol using HPLC analysis. All five bioactive compounds were detected in all 95 roseroot clones but in highly variable quantities. The ranges observed for the different compounds were for rosavin 2.90-85.95mgg-1, salidroside 0.03-12.85mgg-1, rosin 0.08-4.75mgg-1, tyrosol 0.04-2.15mgg-1 and cinnamyl alcohol 0.02-1.18mgg-1. The frequency distribution of the chemical content of each clone did not reflect a certain geographic region of origin or the gender of the plant. Significant correlations were found for the contents of several of these bioactive compounds in individual roseroot clones. A low, but not significant correlation was found between AFLP markers previously used to study the genetic diversity of the roseroot clones and their production of the chemical compounds. The maximum level of rosavin, rosin and salidroside observed were higher than for any roseroot plant previously reported in literature, and the roseroot clones characterized in this study might therefore prove to be of high pharmacological value.
