compounds to plants of Loniceratatarica, and Catharanthusroseus (hybrid) and to suspensioncultures of Rauwolfiaserpentina corroborated that secologanin, vindoline, ajmaline and vomilenine in these plants and cultured cells are biosynthesized via cyclization of 10-oxogeranial/10-oxoneral to iridodial in the same way as secologanin and vindoline in plants of L. morrowii and C. roseus. Therefore, this cyclization
摘要 将各种 3H-、2H-和 13C-标记的化合物喂给忍冬属植物和长春花(杂交)植物以及萝芙木的悬浮培养物的实验证实,这些植物和培养细胞中的赛洛加宁、文多林、阿玛林和伏米林是与 L. morrowii 和 C. roseus 植物中的 secologanin 和 vindoline 一样,通过 10-oxogeranial/10-oxoneral 环化为 iridodial 进行生物合成。因此,这种环化机制似乎在含有类环烯醚萜类和吲哚生物碱的植物中很常见。
