Tanacetum vulgare or Thuja plicata from acetate-[1- 14 C], -[2- 14 C] and -[2- 3 H 3 ] or from CO 2 -[14C] at physiological concentration revealed a pattern of asymmetric labelling whereby tracer predominantly (72–98% resided in that part of the skeleton derived from IPP. This is similar to the patterns previously obtained for uptake of MVA-[2- 14 C] but differed from those reported in other species with
在摄入 14 C 标记的醋酸盐或 CO 2 后,天竺葵和薄荷中形成的香叶醇和 (+)-胡薄荷酮的部分降解表明,这些单萜骨架的 C-2 单元也被标记到不同程度,这些模式在一系列喂养和季节性条件下持续存在。这些结果表明乙酰辅酶A和/或乙酰乙酰辅酶A的代谢库存在于这些植物中。这种池的普遍出现以及随之而来的次级代谢中的非等效标记模式可能会使从标记天然产物的部分降解中得出的生物合成结论无效。
