Diterpene acids from Helianthus species and their microbiological conversion by Gibberella fujikuroi, mutant B1-41a

The diterpene acid content in 10 species of Helianthus has been investigated. Ent-12,16-cyclokauranoic acid, isolated from H. annuus, is converted into a series of 12,16-cyclogibberellins by cultures of Gibberella fujikuroi, mutant B1-41a, and 12,16-cyclogibberellins A 9, and A 12 have been isolated...

Zusammenfassung:The diterpene acid content in 10 species of Helianthus has been investigated. Ent-12,16-cyclokauranoic acid, isolated from H. annuus, is converted into a series of 12,16-cyclogibberellins by cultures of Gibberella fujikuroi, mutant B1-41a, and 12,16-cyclogibberellins A 9, and A 12 have been isolated. Ent-12β-acetoxykaurenoic acid and ent-13( S)-angeloxyatisenoic acid have been isolated from H. decapetalus; the metabolism of ent-13( S)-hydroxyatisenoic acid and atisenoic acid by B1-41a is also described.
