    摘要： Disclosed is a natural herbicidal agent including momilactones A and B, which are identified in and isolated from hulls of rice (Oryza sativa L.). The momilactones A and B inhibit the growth of duckweed (Lemna paucicostata Hegelm 381) at concentrations as low as 1 ppm, and completely inhibit the germination of seeds of three weed species, Leptochloa chinensis L., Amaranthus retroflexus L. and Cyperus difformis L., at 20 ppm.
