title: Two new triterpenoids from Lycopodium obscurum L.
abstract: Two new onoceranoid triterpenoids, (3 alpha,8 beta,14 alpha,21 beta)-26,27-dinoronocerane-3,8,14,21-tetrol (1) and 26-nor-8 beta-hydroxy-alpha-onocerin (2), were isolated from Lycopodium obscurum L. Their structures were elucidated on the basis of spectroscopic analyses.
