石杉碱庚的结构鉴定

STRUCTURAL IDENTIFICATION OF HUPERZINE G

从石杉（Ｈｕｐｅｒｚｉａｓｅｒｒａｔａ（Ｔｈｕｎｂ．）Ｔｒｅｖ．）的正丁醇提取部分分离得到一个新的水溶性石杉类生物碱，通过ＩＲ、ＭＳ、１ＤＮＭＲ和２ＤＮＭＲ确定了其化学结构，命名为石杉碱庚（ｈｕｐｅｒｚｉｎｅＧ）。

A new lycopodium alkaloid, huperzine G was isolated from the n butanol fraction of Huperzia serrata (Thunb.) Trev. The structure of this alkaloid was determined through IR, MS, 1D and 2D NMR spectral analyses.
