The biotransformation of the synthetic (E,E)-1,5-cyclodecadienol 5 and (+)-hedycaryol (11) by a root suspension of fresh chicory has been investigated. Incubation of 5 with a root suspension gave a 2 : 1 mixture of the epimeric eudesmanediols 7a and 7b whereas 11 was selectively converted into cryptomeridiol (12). An explanation for the obtained results is proposed.
Sesquiterpenes isolated from Alpinia speciosa and Alpinia japonica, and their derivatives were found to inhibit histamine- or barium chloride-induced contraction of excised guinea pig ileum when tested by the Magnus method. Major spasmolytic principles contained in those extracts were the sesquiterpenes, β-eudesmol, nerolidol, humulene epoxide II and 4α-hydroxydihydroagarofuran. Relationships between the chemical structures of the sesquiterpenes and their derivatives, and their spasmolytic activities were discussed.
通过马格努斯法测试发现,从白山药和白山药中分离出的倍半萜及其衍生物可抑制组胺或氯化钡引起的切除豚鼠回肠收缩。这些提取物所含的主要解痉成分是倍半萜、β-桉叶油醇、橙花叔醇、环氧化葎草烯 II 和 4α-羟基二氢豨莶草醚。讨论了倍半萜及其衍生物的化学结构与它们的解痉活性之间的关系。
