| Abstract/Contents: | "Six grass species (zoysiagrass, bermudagrass, centipedegrass, tall fescue, St. Augustinegrass, and Kentucky bluegrass) were analyzed for polyphenols and flavonoids by high performance liquid chromatography. Each gave a characteristic leaf chemistry profile that allowed it to be differentiated from the other grasses. `Emerald' zoysiagrass was characterized by the presence of chlorogenic acid and a group of luteolin-glycosides containing glucose and/or arabinose. `Tifgreen' bermudagrass contained no chlorogenic acid, and at least two of the flavonoids were apigenin-glycosides in addition to several luteolin-glycosides. Common centipedegrass and Ky 31 tall fescue both contained high levels of chlorogenic acid, but their flavonoid composition was different. Centipedegrass contained luteolin-type flavonoid-glycosides and maysin, an unusual luteolin-diglycoside that possesses a unique keto-sugar. Tall fescue contained quercetin-type flavonoids rather than luteolin. Rutin was found as a major constituent of tall fescue. `Kenblue' Kentucky bluegrass and `Raleigh' St. Augustinegrass contained no chlorogenic acid. These two grasses contained several luteolin-glycosides but not the broad, multiple flavonoid. proflies of zoysiagrass and bermudagrass. Fall armyworm [FAW; Spodoptera frugiperda (J.E. Smith)] larval growth was significantly affected by the type of grass they fed upon in laboratory no-choice tests. Fall armyworm larval weight reductions (as a percentage of the bermudagrasses) at 7 d after infestation were 90, 79, and 29% for zoysiagrass, centipedegrass, and St. Augustinegrass, respectively. Chlorogenic acid, luteolin, and the flavonoid-glycosides rutin, maysin, and isoorientin were highly active in a laboratory bioassy in reducing FAW larval weights; however, no correlations could be made between FAW resistance and the levels of chlorogenic acid, flavonoids, or total phenolics extractable from the grasses evaluated." |
