Ten gibberellins (GAs) have been identified by Kovats retention indices and full mass spectra from GC-MS analysis of purified extracts of sporophytes of the tree-fern, Cyathea australis. These include the known GA(1), GA(4), GA(9), GA(15), GA(24), GA(35), and GA(58) and three new GAs, 12beta-hydroxyGA(9) (GA(69)), 12alpha-hydroxyGA(9) (GA(70)) and 12beta-hydroxyGA(4) (GA(71)). The structure of GA(71) was established by the preparation and characterization of its methyl ester (as a metabolite of GA(4) methyl ester in a culture of prothallia of Lygodium japonicum).
已通过气相色谱-质谱联用分析从树蕨桫椤的孢子体纯化物中鉴定出 10 种赤霉素(GA),并通过其科瓦茨保留指数和全质谱确定了它们的结构。这其中包括已知的 GA(1)、GA(4)、GA(9)、GA(15)、GA(24)、GA(35)和 GA(58),以及三种新的 GA:12β-羟基 GA(9)(GA(69))、12α-羟基 GA(9)(GA(70))和 12β-羟基 GA(4)(GA(71))。GA(71)的结构是通过其甲酯的制备和表征确定的(作为在海金沙原叶体培养物中 GA(4)甲酯的代谢产物)。
