Abstract: A new Lycopodium alkaloid , diphaladine A (1 ) , was isolated from the 95% EtOH extract of Diphasiastrum complanatum together with other nine known alkaloids . Their structures were elucidated on the basis of extensive spectroscopic analysis. To the best of our knowledge , obscurumine A (2 ) , L20 , lycoposerramine-K, des-N-methyl-β-obscurine, des-N-methyl-α-obscurine , lycoflexion , and phlegmariurine B were all isolated from this plant for the first time .
