5-n-alkylresorcinols from grains of winter barley (Hordeum vulgare L.)

摘要

The resorcinolic lipid content and homologue composition of winter barley grains harvested at two field locations were evaluated. Depending on the crop location, the predominant alkylresorcinols identified were 1,3-dihydroxy-5-n-heneicosylbenzene or 1,3-dihydroxy5-n-pentacosylbenzene. Both resorcinol concentration and their homologue profiles were diverse in samples harvested at different fields indicating a prevailing role of the environment upon the alkylresorcinol biosynthesis in cereals.
