M. Penny et al., PREPARATION OF GIBBERELLINS A(91) AND A(92) AND THEIR OCCURRENCE IN DEVELOPING WHEAT-GRAIN, Phytochemistry, 37(4), 1994, pp. 1063-1067
Extracts of endosperm of developing grains of Triticum aestivum (cv Ma
ris Huntsman) were analysed by GC-MS and found to contain a previously
known synthetic compound, 1 beta-hydroxyGA(5), now named GA(92), The
structure of a new GA metabolite, 2 beta-hydroxyGA(60), was confirmed
by comparison with a synthetic sample prepared in nine steps from GA(3
) methyl ester and assigned the trivial name GA(91).
