| Abstract: | Three novel gibberellins, GA54 (ent-1α, 3α, 10-trihydroxy-20-norgibberell-16-ene-7, 19-dioic acid 19, 10-lactone), GA55 (ent-1α, 3α, 10, 13-tetrahydroxy-20-norgibberell-16-ene-7, 19-dioic acid 19, 10-lactone) and GA56 (ent-2β, 3α, 10, 13-tetrahydroxy-20-norgibberell-16-ene-7, 19-dioic acid 19, 10-lactone) were shown to occur in the culture broth of Gibberella fujikuroi. Their structures were determined mainly by mass spectrometrical comparison of the derivatives with those of authentic compounds prepared from known gibberellins. |
