The chemical constituents of Huperzia serrata Trev. are mainly flavonoids, triterpenoids and alkaloids. In order to get further comprehension of lycopodium alkaloids, we studied the low-polar section of the alkaloids extraction of Huperzia serrata and 19 alkaloids were isolated by ways of silica gel, RP-18 and Sephadex LH-20 etc. All of their structures, including five new compounds and two known ones that were firstly found from this genus, were elucidated with the help of Mass, IR, NMR spectra and so on. The five new alkaloids (HS-07, HS-08, HS-09, HS-10 and HS-11) are belonged to lycopodine class. The other two ones that were new to this genus (HS-18 and HS-19) are belonged to miscellaneous group.

蛇足石杉的主要化学成分为黄酮，三萜和生物碱，为进一步了解该植物的生物碱成分，我们研究了蛇足石杉氯仿总碱低极性部位的生物碱成分，运用正相硅胶、反相RP-18、凝胶LH-20等方法分得了19个生物碱，并通过质谱、红外、核磁共振等波谱鉴定了它们的结构，其中5个为新化合物，2个为首次从该属植物中分离得到的化合物，所分得的新化合物：HS-07、HS-08、HS-09、HS-10和HS-11均为lycopodine类石松生物碱，首次从该属植物中分得的化合物为miscellaneous类：HS-18和HS-19。
