Abstract Extracts of mature grain of Triticum aestivum (cv Maris Huntsman) were analysed by GC-MS and found to contain two gibberellins with a 1β,2β-vicinal diol, namely GA 79 and a new gibberellin, 2β-hydroxyGA 61 . The structure of the new GA metabolite was confirmed by comparison with a synthetic sample prepared in nine steps and 15% overall yield from GA 7 methyl ester and assigned the GA number
摘要 用 GC-MS 分析小麦 (cv Maris Huntsman) 成熟谷物的提取物,发现含有两种赤霉素和 1β,2β-邻二醇,即 GA 79 和一种新赤霉素,2β-羟基GA 61 。新 GA 代谢物的结构通过与 GA 7 甲酯分九步制备的合成样品进行比较得到确认,GA 7 甲酯的总产率为 15%,并指定了 GA 编号 GA 90。描述了通向 GA 79 和 GA 90 的合成路线。
