A Comparison of the Occurrence of Bioactive Compounds in the Grain of Different Triticum Species

This review is a collection of information on bioactive compounds found in the grain of different <i>Triticum</i> species, both old and modern. The whole wheat grain, as well as its parts, e.g., bran, contains compounds, such as phenolic acids, flavonoids, alkylresorcinols, benzoxazinoids, tocopherols, carotenoids, and others. These compounds differ in both their chemical structure and biological properties. There are significant differences in the content and composition of these compounds between <i>Triticum</i> species. Apart from the wheat species, there are many other factors influencing these differences, e.g., cultivars, environmental factors, growth conditions, and farming systems. The <i>Triticum</i> species the best researched and described in terms of the content of bioactive compounds are <i>Triticum aestivum</i> L., <i>T. durum</i> Desf., <i>T. spelta</i> L., <i>T. turgidum</i> L., <i>T. monococcum</i> L., <i>T. dicoccum</i> Schrank, <i>T. timopheevii</i>, and <i>T. polonicum</i> L.
