(2014) IDENTIFICATION OF POTENTIAL AND POTENCY OF ALLELOCHEMICALS IN VELVETBEAN COCHINCHINESIS (WIGHT) BURCK) FOR THE CONTROL OF STRIGA HERMONTHICA (DEL.) BENTEhttps://keffi.nsuk.edu.ng/handle/20.500.14448/3060The experiment was cot ducted 1 the Toxicology laboratory. Faculty 0Agriculture, University Putra Malaysia؛ Sc d ng, Malaysia in 1013, The study was to identify plant growth-inhibitory cotnpounds in ا . cochinchinensis م a 0 clarifying the weed-suppressing effect o f this plant. The treatments consisted o f five concentrations (100, 75. 50. 25. ٠ ppnt); pla٦٦t parts (leaf, root, seed) and extraction solvents (methanol, water) were replicated three times and arranged as a completely randomi ed block (CRD) design, in all the treatments, inhibition from root u w greater than from leaves. The seed extract showed less inhibition. Six phenolic/fiavonone compounds including gallic acid, cajfeic acid, L-dopa, tyrosine, quercetin and isovitexin were isolated and identified in velvetbean leaves, root and seed. Concentration of these phenolic compounds in root was higher than in the leaves. These compounds showed different degrees o f inhibition against Striga hermonthica and therefore results in the stronger allelopathic activity o f M. cocb cin-ensiSi The identification o f these substances might provide cliemical basis for the development o f bio-herbicides for environmentally friendly sustainable agricultural systems.enVelvet bean, Striga, Identification, Phenolic compoundsArticle
