Isolation and characterization of the unstable allene oxide. A, SP-HPLC profile of the allene oxide methyl ester from 12R-hydroperoxy-linolenic acid chromatographed on a silica column (4.5 × 0.46 cm) with the solvent hexane/ether (100/1, v/v) at a flow rate of 3 ml/min. All procedures were performed at −15 °C. B, UV spectrum of the allene oxide showing the maximum absorbance at 236.5 nm. C, 1H NMR spectrum of the allene oxide methyl ester recorded at −20 °C in d-hexane.
