Abstract:
To study the triterpenoid constituents from air-dried whole plants of Lycopodium obscurum L., the constituents were isolated by normal-phase and reverse-phase silica gel column chromatography from the EtOAc extract. Their structures were elucidated on the basis of spectral analysis. Five triterpenoids were purified and identified as 3beta, 19alpha-dihydroxy-20beta-acetate-serrat-14-en-21beta-ol (1), serratenediol (2), alpha-onocerin (3), 26-nor-8-oxo-alpha-onocerin (4), (3beta, 8beta, 14alpha, 21alpha)-26, 27-dinoronocerane-3, 8, 14, 21-tetrol (5). Compound 1 is a new serratane-type triterpene and compound 5 is isolated from this plant for the first time.
