STRUCTURES OF THREE NEWENT-LONGIPINANE TYPE SESQUITERPENOIDS FROM THE LIVERWORTMARSUPELLA EMARGINATASUBSP.TUBULOSA
摘要:
Three new sesquiterpenoids were isolated from the liverwort Marsupella emarginata subsp. tubulosa. The structures and absolute configurations of the compounds have been shown to be (−)-marsupellone(1), (+)-marsupellol(2) and (+)-acetoxymarsupellone(3), containing an ent-longipinane skeleton, on the basis of chemical and spectral evidence.
