红树植物水黄皮pongamia pinnata中一个生物碱的分离与结构表征

Isolation and Structure Characterization of Dehydrocorydaline from Mangrove pongamia pinnata

利用各种层析手段,从海南红树植物水黄皮 pongamia pinnata 的正丁醇部分中分离纯化了一个生物碱类化合物,通过各种波谱实验(1D-NMR,2D-NMR,ESI-MS)确定其结构为:dehydrocorydaline(1)。该化合物为首次从红树植物水黄皮中分离得到。

In our continued searching for bioactivity compounds from marine source,we have made chemical investigation on Hainan mangrove pongamia pinnata,An alkaloid has been isolated from the BuOH fraction of 80% EtOH extraction of the whole plant.The structure was established mainly by varous NMR(~1H NMR,^(13)C NMR,COSY,HMQC,HMBC)and ESI-MS experiment.The structure is determined as: Dehydrocorydaline(1).
