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, GA111 and GA112. Evidence for endogenous 1-epi GA61 (GA119) and 11alpha-OH-GA12 was also obtained. In addition, a number of putative GAs were detected. Of these, three were shown to be 12alpha-hydroxy-GA53, 12alpha-hydroxy-GA44, and 12alpha-hydroxy-GA19 by comparison with authentic compounds prepared by rational synthesis, and have been allocated the descriptors GA123, GA124 and GA125, respectively.

摘要

采用气相色谱 - 质谱联用技术分析了草莓（Fragaria x ananassa Duch. cv. Elsanta）未成熟果实中羧酸提取物的赤霉素。通过将其质谱图和科瓦茨保留指数（KRIs）与标准品或已发表数据进行比较，鉴定出了以下先前已表征的赤霉素：GA1、GA3、GA5、GA8、GA12、GA17、GA19、GA20、GA29、GA44、GA48、GA49、GA53、GA77、GA97、GA111和GA112。还获得了内源性1-表GA61（GA119）和11α-羟基-GA12的证据。此外，还检测到了一些假定的赤霉素。其中，通过与合理合成制备的真实化合物进行比较，确定其中三种为12α-羟基-GA53、12α-羟基-GA44和12α-羟基-GA-19，并分别赋予描述符GA123、GA124和GA125。
