Sorghum (Sorghum bicolor) is an important food crop in Africa and a host of the devastating root parasitic weed Striga hermonthica. Seeds of root parasitic weeds germinate only when they are exposed to exogenous germination stimulants produced by and released from roots of host and some non-host plants. Sorghum has already been shown to exude sorgolactone, strigol, and 5-deoxystrigol. In addition to these known strigolactones, an isomer of strigol was identified in root exudates of sorghum cultivars M800 and Hybrid. This novel strigolactone, named sorgomol, was isolated and its structure was determined as (3aR,8R,8bS,E)-8-(hydroxymethyl)-8-methyl-3-(((R)-4-memyl-5-oxo-2,5-dihydromran-2-yloxy)methyleme)-3a,4,5,6,7,8-hexahydro-3H-indeno[1,2-b]furan-2(8bH)-one by 1D and 2D NMR spectroscopy and ESI- and EI-MS spectrometry.
