Abstract

A potent growth inhibitor was isolated from blue light-illuminated sunflower (Helianthus annuus) hypocotyls and identified as 8-(β-D-glucopyranosyloxy)-3-hydroxy-1,9,14-pentadecatriene-4,6-diyne (1, designated "helian") from analysis of its 1H and 13C NMR spectra, and HRFABMS. Helian 1 showed plant growth-inhibitory activity at concentrations higher than 2.6 × 10-6 mol/L for the cress root growth test. The amount of helian was higher in the illuminated halves than in the shaded ones in phototropically stimulated sunflower hypocotyls. These results suggest that this new potent growth inhibitor, helian, may play an important role on phototropism of sunflower hypocotyls.
