Abstract

The essential oil of the liverwort Plagiochila bifaria was analysed by GC and GC-MS. Three eudesmane type sesquiterpenes, ent-eudesm-4-en-6-one, ent-eudesm-4(15)-en-6-one, ent-7-hydroxyeudesm-4-en-6-one were isolated and identified as new natural products. Structure elucidation and the determination of absolute configurations are described.

摘要

对叶苔（Plagiochila bifaria）的精油进行了气相色谱（GC）和气相色谱-质谱联用（GC-MS）分析。分离并鉴定出三种桉叶烷型倍半萜类化合物，即对映-桉叶-4-烯-6-酮、对映-桉叶-4(15)-烯-6-酮、对映-7-羟基桉叶-4-烯-6-酮，它们均为新的天然产物。描述了其结构解析和绝对构型的确定。
