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.
两个新的石松生物碱,(+) - cermizine d Ñ氧化物(1)和(8 β)-8-(乙酰氧基)obscurumine A(2)中,用5点已知的化合物一起,被从粗生物碱部分隔离玉柏。根据光谱数据和化学相关性阐明了它们的结构。所有这些生物碱均通过乙酰胆碱酯酶(AChE)抑制活性试验进行了测试。
