Alkyl resorcinols in grains from plants from the family Gramineae

Abstract

5-n-alkylresorcinols were found in 22 of the 27 studied species of grasses. In <em>Agropyron caninum</em> and <em>Bromus macrostachys</em> only the content of alkyl resorcinols was determined, in <em>Agropyron repens, Bromus mollis</em> and <em>Elymus arenarius</em> the composition of alkyl resorcinol homologues was also established. When calculated per gram of dry mass of air-dried grains, the content of alkyl resorcinols was found to be: in the genus <em>Agropyron</em> - approximately 715 µg, in the genus <em>Bromus</em> approximately 60 µg and in <em>Elymus</em> arenarius, 272 µg. The homologues of alkyl resorcinods in the studied genera of grasses differ from the homologues found in wheat or rye by their greater content of long-chain fractions.
