The ether extract of the liverwort Chiloscyphus polyanthos afforded sesquiterpenoids which are enantiomeric to those found in another liverwort Lepidozia vitrea. The absolute configurations of the sesquiterpenoids found in the title species were determined by spectroscopic evidence, chemical derivatization and /or X-ray crystallographic analysis.
地草 Chiloscyphus polyanthos 的醚提取物提供了倍半萜类化合物,其与另一种地草 Lepidozia vitrea 中发现的化合物是对映异构体的。在标题物种中发现的倍半萜类化合物的绝对构型是通过光谱证据、化学衍生化和/或 X 射线晶体学分析确定的。
