Two pyranoisotlavones, alpinumisoflavone and 4' -rnethyl-alpinumisoflavone and methyl 2-([3-D-glucopyranosyloxy) benzoatc were isolated trom the aerial parts of Pueraria phaseoloides. Phytotoxic effects of these compounds and of the P. phaseoloides hydroalcoholic extract fractions obtained by liquid-liquid partition were examined in Petri dish bioassay. The dichloromethanic and ethyl acetate tractions had a significant effect 011 seed germination of the weed species Mimosa pudim, showing 100 and 76 % inhibition, respectively. However, the three isolated compounds had a greater effect on radicle elongation of the weed species Mimosa pudim. Senna obtusifolia, Senna occidentalis and Urena lobata. 4'-Methylalpinumisoflavone at the highest dose tested (3.0 ppm) exhibited stronger inhibition (77 %) on S. obtusifolia, whereas, alpinumisotlavone at 3.0 ppm was more active (60% inhibition) on U. lobata and methyl 2-([3-D-glucopyranosyloxy) benzo ate at 4.0 ppm (the highest dose tested) showed significam inhibition (44 %) on M. pudim. Our experimental data showed that three natural products tested have selective herbicidal activity against weed species. |
