Detection and identification of complex oxylipins in meadow buttercup (Ranunculus acris) leaves.

Screening of linolipins, i.e. galactolipids containing esterified residues of divinyl ether oxylipins, in the leaves of several higher plants revealed the presence of these complex oxylipins in the meadow buttercup leaves.

Isolation and structure elucidation of linolipins C and D, complex oxylipins from flax leaves.

Two complex oxylipins (linolipins C and D) were isolated from the leaves of flax plants inoculated with phytopathogenic bacteria Pectobacterium atrosepticum. Their structures were elucidated based on UV, MS and NMR spectroscopic data. Both oxylipins were identified as digalactosyldiacylglycerol (DGDG) molecular species.

Unprecedented pathogen-inducible complex oxylipins from flax--linolipins A and B.

Oxylipins constitute a large family of bioregulators, biosynthesized via unsaturated fatty acid oxidation. This study reports the detection of an unprecedented family of complex oxylipins from flax leaves. Two major members of this family, compounds 1 and 2, were isolated and purified.
