Isolation and stomatal opening activity of two oxylipins from Ipomoea tricolor.
Bioassay-guided fractionation of a 50% MeOH extract of Ipomoea tricolor enabled the isolation of two oxylipins, cis-12-oxophytodienoic acid (OPDA, 1) and a novel monogalactosylmonoacylglyceride (2) containing OPDA, that acted as inducers of stomatal opening. These oxylipins enhanced stomatal opening of Commelina communis in darkness at micromolar concentrations.
