| Abstract/Contents: | "Corn gluten hydrolysate (CGH) has been observed to inhibit root formation of germinating grass seeds and has the potential for use as a natural herbicide. Five dipeptides have been isolated from the aqueous solution of CGH and proved to have greater root-inhibiting activity than the crude extract of CGH. The objective of this study was to isolate and identify other biologically active compounds from CGH with herbicidal properties. A perennial ryegrass (Lolium perenne L.) Petri dish bioassay was used to test for the bioactivity. A pentapeptide, Leu-Ser-Pro-Ala-Gln, was isolated fron CGN by using Sephadex G-15 gel filtration and two-step C18 reversed phase high performance liquid chromatography procedures. The compound suppressed growth of both the root and the shoot of germinating perennial ryegrass. It required 0.5 mg/mL of the pentapeptide to inhibit 50% of root length in the perennial ryegrass bioassay, and this compound is more active than any of the five dipeptides isolated previous from CGH." |
