Abstract: An examination was made of the effects of various ethanol concentrations on the extraction of crude yield and allelopathic activity of Murraya paniculata L. Various water-ethanol concentration (0, 25, 50, 75 and 100%, v/v) was extracted by maceration method on dried leaf of M. paniculata at 1: 10 w/v by three times. The highest crude yield was obtained in 50% ethanol by three times extraction followed by 25%, 0%, 75% and 100% respectively. Each crude extract was tested the allelopathic activity to inhibit the germination and seedling growth of Echinochloa crus-galli and Trianthema portulacastrum L. on the concentrations of 0, 0.25, 0.5, 1 and 2% by petri dish test. The results showed that all crudes did not inhibit seed germination of E. crus-galli and T. portulacastrum, however they effected on seedling survival and seedling growth. The crude of 100% ethanol showed the highest inhibitory effect on root growth of E. crus-galli and T. portulacastrum. The inhibitory level dramatically decreased with reducing on ethanol percentage.
