Abstract/Contents:"Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) of cereal grain proteins has received much attention in the literature in recent years as a quick and efficient means of cultivar identification. A study of perennial ryegrass (Lolium perenne L.) and annual ryegrass (Lolium multiflorum Lam.) was undertaken to determine if RP-HPLC could be adapted to the identification of these species. Chromatograms of the different cultivars of the seed kinds studied all had distinct peak patterns, which correlated with each of the two species. Cultivar differences within each species group were distinct enough so that all of the cultivars were distinguished from each other. RP-HPLC was shown to be a quick, repeatable and reliable method of ryegrass species and cultivar identification for a general screening of seed lots. Protein analysis of single seeds could differentiate annual ryegrass seeds from perennial ryegrass seeds. Mixtures and blends of ryegrass were analyzed and compared. The sensitivity of the detector was such that the changes of area under the peaks of the chromatogram were able to detect a lower limit of 5% annual ryegrass in perennial ryegrass."
