Preparation and occurrence of gibberellins A75 and A76 and 3-epi-A72
Abstract
Three water-soluble compounds were detected in extracts from mature seeds of Helianthus annuus by g.l.c.–mass spectrometry. The structures of these putative gibberellins were confirmed by comparison with authentic samples of the 15β-hydroxygibberellins GA75, GA76, and 3-epi-GA72 prepared from GA3.
