Abstract

Extracts of carboxylic acids from immature fruits of strawberry (Fragaria x ananassa Duch. cv. Elsanta) were analysed for gibberellins by combined gas chromatography-mass spectrometry. The following previously characterised gibberellins were identified by comparison of their mass spectra and Kovats retention indices (KRIs) with those of standards or published data: GA1, GA3, GA5, GA8, GA12, GA17, GA19, GA20, GA29, GA44, GA48, GA49, GA53, GA77, GA97, GA111and GA112. Evidence for endogenous 1-epi GA61 (GA119) and 11α-OH-GA12 was also obtained. In addition, a number of putative GAs were detected. Of these, three were shown to be 12α-hydroxy-GA53, 12α-hydroxy-GA44, and 12α-hydroxy-GA19 by comparison with authentic compounds prepared by rational synthesis, and have been allocated the descriptors GA123, GA124 and GA125, respectively.
