摘要：

Root exudate of Vigna unguiculata was extracted from a soil system consisting of charcoal and vermiculite. Germination stimulating activity for Striga gesnerioides was found in extracts of the soil system, and an active compound was isolated. The chemical structure of the active ingredient was determined to be (+)-4-O-acetylorobanchol, based on analysis of the spectral data of 1-D and 2-D NMR together with nuclear Overhauser effect (NOE) experiments. Application of the active compound to the seeds of S. gesnerioides at a concentration of 0.35 x 10(-9) mol/disk led to 69% germination. The germination observed with application of GR-24, a positive control, at 0.57 x 10(-10) mol/disk was 80%.
