Two new Lycopodium alkaloids, (+)‐cermizine D N‐oxide (1) and (8β)‐8‐(acetyloxy)obscurumine A (2), along with five known compounds, were isolated from the crude alkaloid portion of Lycopodium obscurum. Their structures were elucidated on the basis of spectroscopic data and chemical correlation. All of these alkaloids were tested in an assay for acetylcholine esterase (AChE) inhibitory activity.
The seven new triterpenoid saponins 1–7 were isolated from the roots of Gypsophila paniculata L. Their structures were established by 1D‐ and 2D‐NMR techniques, HR‐MS, and acid hydrolysis. The isolated compounds include 3,28‐O‐bidesmosides with or without a 4‐methoxycinnamoyl group (see 1vs.2 and 3), and 3‐O‐monoglucosides 4–7. All isolated saponins 1–7 and their aglycones were evaluated for their...
