Abstract

Strigolactones are plant secondary metabolites that function as host recognition signals for arbuscular mycorrhizal fungi and root parasitic plants, Striga and Orobanche, and, in addition, plant hormones inhibiting shoot outgrowth. In this study, a novel strigolactone fabacyl acetate was purified from root exudates of pea (Pisum sativum L.) and its structure was determined as ent-2'-epi-4a,8a-epoxyorobanchyl acetate, by 1D and 2D NMR spectroscopy, ESI- and EI-MS spectrometry, X-ray crystallography, and by comparing ^1H NMR spectral data and retention times in LC-MS and GC-MS with those of synthetic standards prepared from (+)-orobanchol and (+)-2'-epiorobanchol. The ^1H NMR spectral data and retention times of fabacyl acetate were identical with those of an isomer prepared from (+)-2'-epiorobanchol except for the opposite sign in CD spectra.
