説明
Abstract A plant growth inhibitor, dihydro-5,6-dehydrokawain, has been isolated from Alpinia speciosa leaves. Its chemical structure was elucidated from spectroscopic data and by synthesis. This compound caused a 35% reduction in hypocotyl length of lettuce seedling compared to the control at 25 ppm, etiolation at 100 ppm and necrosis at 200 ppm. Subsequently, we synthesized some related compounds. Among these, 4-methoxy-6-( m -chlorophenethyl)-2H-pyran-2-one was much more active, causing a 66% growth retardation at 25 ppm.
