Five new sesquiterpenes were isolated from Acorus calamus L., in addition to calameone (or calamendiol), the structure of which was revised, and their structures were established. Furthermore, chemical co-relation among these sesquiterpenes was carried out. In particular, the thermal isomerization of shyobunone (I), an elemene-type sesquiterpene, to preisocalamendiol (VI), a germacrone-type compound
从cal蒲中分离出五个新的倍半萜烯,除了其甘草酮(或甘瓜二醇),并对其结构进行了修改,并确定了它们的结构。此外,在这些倍半萜之间进行了化学相关。特别地,应该注意的是,将玉兰酮型倍半萜烯(Syobunone)(I)热转化为胚芽酮型化合物异二十烷二醇(VI)。
