Alkyl resorcinols in grains from plants from the family Gramineae

Grzegorz Kubus, Franciszek Tłuścik

Abstract


5-n-alkylresorcinols were found in 22 of the 27 studied species of grasses. In Agropyron caninum and Bromus macrostachys only the content of alkyl resorcinols was determined, in Agropyron repens, Bromus mollis and Elymus arenarius 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 Agropyron - approximately 715 µg, in the genus Bromus approximately 60 µg and in Elymus 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.
