• 中文摘要： 葉蘚植物Scapania robusta的倍半?碳氫化合物組成經分離後光譜分析推定含anastreptene(3), longifolene(5), se-
  lina-4.11-diene(9), 及α-selinene(10)。由氣相層析的兩不同極性液相之柯氏指數比較，尚可能含下列化合物：cyclosa-
  tivene, sinuene, scapanene, α-humulene, α-amorphene, aequilobene, β-selinene, cuparene（或calamenene
  ），及5.10-epi-α-selinene。此外，由本植物中尚分離出一70%純度的不明倍半?，由其GC柯氏指數及nmr光譜初步判
  斷，可能為一新化台物。o
• 英文摘要： In the course of a systematic survey of the chemical constituents of liverworts grown in Taiwan,the oil of Scapania robusta was examined and found to contain sesquiterpene hydrocarbons anastreptene(3), longifolene (5), selina-4, 11-diene (9), and α-selinene (10) by spectral evidence. Other possible com-portents are cyclosativene, sinuene, scapanene, α-humulene, α-amorphene, aequilobene, β-selinene, cuparene(or calamenene) and 5, 10-epi-α-selinene on the basis of GC retention data. In addition, an unidentifiedsesquiterpene was isolated and appeared to be a new compound, as judged from the GC retention indicesand NMR spectrum of the partially pure material.
