Identification of three C20-gibberellins : GA97 (2β-hydroxy-GA53), GA98 (2β-hydroxy-GA44), and GA99 (2β-hydroxy-GA19)

Identification of three C20-gibberellins : GA97 (2β-hydroxy-GA53), GA98 (2β-hydroxy-GA44), and GA99 (2β-hydroxy-GA19)

Three new C20-gibberellins, GA97 (2 beta-hydroxy-GA53), GA98 (2 beta-hydroxy-GA44) and GA99 (2 beta-hydroxy-GA19), have all been isolated from spinach, GA97 also from tomato root cultures and pea pods, and GA98 from maize pollen. The structures of these compounds were established by GC-mass spectrom...

Zusammenfassung:Three new C20-gibberellins, GA97 (2 beta-hydroxy-GA53), GA98 (2 beta-hydroxy-GA44) and GA99 (2 beta-hydroxy-GA19), have all been isolated from spinach, GA97 also from tomato root cultures and pea pods, and GA98 from maize pollen. The structures of these compounds were established by GC-mass spectrometric comparisons of the trimethylsilylated methyl esters with authentic samples prepared from gibberellic acid (GA3).
