Abstract The transformation of germacrone, a 10-membered ring sesquiterpene, by suspension culturedcells of Lonicera japonica, Bupleurum falcatum, Polygonum tinctorium and solidago altissima , was investigated. Germacrone was converted into several types of sesquiterpenes, such as guaiane, eudesmane and seco-guaiane and their structures were determined from spectral and chemical evidence. The configurations
摘要 研究了金银花、柴胡、何首乌和一枝黄花悬浮培养细胞对10元环倍半萜基麦角酮的转化。Germacrone 被转化为几种类型的倍半萜,如愈创木、eudesmane 和 seco-guaiane,它们的结构由光谱和化学证据确定。一些产品的构型是通过 CD 光谱确定的。讨论了四种悬浮培养细胞在产品种类上的差异。

The biotransformation of germacrone-4,5-epoxide (2), germacrone-1,10-epoxide (3), isogermacrone-4,5-epoxide (5), germacrene B-4,5-epoxide (6) and germacrene B-I,10-epoxide (7) by a suspension of fresh chicory root (Cichorium intybus) was investigated. Enzyme catalysed cyclisations towards substituted guaianes and eudesmanes were observed.
