摘要
从虎皮楠属植物交让木(Daphniphyllum macropodum)乙醇提取物的氯仿萃取部分分离得到5个生物碱,采用核磁共振(1H-NMR、13C-NMR、DEPT)和ESI-MS波谱解析技术对其结构进行鉴定,最终分别确定为Daph-nilactone(1)、Paxdaphnine B(2)、Methyl homosecodaphniphyllate(3)、Paxdaphnine A(4)和Daphnigraciline(5)。并检测了上述生物碱的杀卤虫活性,发现化合物2具有微弱的活性。
Five alkaloids were isolated from the chloroform part of ethanol extracts of Daphniphyllum macropodum Miq.using classic phytochemistry techniques in the present work.They were identified as Daphnilactone（1）,Paxdaphnine B（2）,Methyl homosecodaphniphyllate（3）,Paxdaphnine A（4） and Daphnigraciline（5） by spectroscopic analysis methods including 1H-NMR,13C-NMR,DEPT,and ESI-MS.The activities against Artemia Salina were evaluated,and compound 2 showed weak effect.
