3-EPI-GA63, ANTHERIDIOGEN IN ANEMIA PHYLLITIDIS

Article abstract of DOI:10.1016/0031-9422(94)00834-G

3-Epi-Gibberellin A₆₃ (3-epi-GA₆₃) was identified by full-scan GC-mass spectrometry of a purified extract from culture media of prothallia of the fern, Anemia phyllitidis.This is the third antheriodiogen, following antheridic acid and 3α-hydroxy-9,15-cyclo-GA₉, in this species. 3-Epi-GA₆₃ showed slightly less activity than antheridic acid in antheridial formation and dark spore germination assays. - Key words: Anemia phyllitidis; Schizaeaceae; fern; prothallia; antheridiogen; antheridic acid; 3-epi-gibberellin A₆₃.
