ent-1 α，10，13-三羟基-20-降赤霉素-16-烯-7，19-二酸19，10-内酯（GA 60）和对映异构体-1 α，以赤霉素3和赤霉素7为原料，分别合成了10-二羟基-20-去甲赤霉素-16-烯-7，19-二酸19，10-内酯（GA 61），经GLC-质谱分析，与小麦籽粒发育过程中检测到的2种赤霉素相同。ent-1 α，10-二羟基-20-去甲赤霉-2，16-二烯-7，19-二酸19，-10-内酯（GA 62）是由赤霉酸（GA 7）合成的。小麦GA61和GA62在苹果梨未成熟种子中检测到。尝试制备第四个推定的GA 4，在T.但没有成功。
ent-1.alpha.,10,13-Trihydroxy-20-norgibberell-16-ene-7,19-dioic acid 19,10-lactone (GA60) and ent-1.alpha.,10-dihydroxy-20-norgibberell-16-ene-7,19-dioic acid 19,10-lactone (GA61) were prepared from GA3 and GA7, respectively, and are identical with 2 GA previously detected by GLC-mass spectrometry in developing grains of Triticum aestivum. ent-1.alpha.,10-Dihydroxy-20-norgibberella-2,16-diene-7,19-dioic acid 19,-10-lactone (GA62) was prepared from GA7 and is present in the grain of T. aestivum. GA61, and GA62 were detected in immature seed of Pyrus malus. Attempts to prepare a 4th putative GA4, detected in T. aestivum, were not successful.
