摘要
Four new sesquiterpenes and nine known compounds were isolated from the ether extract of the liverwort Reboulia hemisphaerica. Their structures were established by spectral and chemical evidence. The structures of the new compounds were shown to be gymnomitr-8(12)-en-4-one, ent-arist-9-en-8 alpha-ol, 6 beta, 10 beta-epoxycupar-3-ene and 3(15)-thujopsen-10 alpha-ol.
