The diterpene acid content in 10 species of Helianthus has been investigated. Ent-12,16-cyclokauranoic acid, isolated from H. annuus, is converted into a series of 12,16-cyclogibberellins by cultures of Gibberella fujikuroi, mutant B1-41a, and 12,16-cyclogibberellins A9, and A12 have been isolated. Ent-12β-acetoxykaurenoic acid and ent-13(S)-angeloxyatisenoic acid have been isolated from H. decapetalus;
摘要 对10种向日葵中的二萜酸含量进行了研究。Ent-12,16-环甲壳酸,从一年生草中分离出来,通过藤黑赤霉、突变体 B1-41a 和 12,16-环赤霉素 A9 和 A12 的培养转化为一系列 12,16-环赤霉素. Ent-12β-acetoxykaurenoic acid 和 ent-13(S)-angeloxyatisenoic acid 已从 H. decapetalus 中分离出来;还描述了 B1-41a 对 ent-13(S)-羟基二烯酸和二烯酸的代谢。
