Application of [1,2‐ 14 C]1‐deoxy‐ d ‐xylulose, the committed precursor of terpenoids, thiamine and pyridoxol, to a variety of plant species resulted in the labelling of an unknown metabolite. The isolation and purification of this metabolite from Ipomoea purpurea plants fed with 1‐deoxy‐ d ‐xylulose (DX), followed by NMR analysis, resulted in the identification of its structure as (−)‐2C‐methyl‐ d ‐erythrono‐1,4‐lactone (MDEL). MDEL has been previously isolated as a stress metabolite of certain plants. A hypothetical biosynthetic scheme is given.
