The Lycopodiwn alkaloids discovered from January, 1994 to March, 2003, and the research progress of huperzine A (HA) were reviewed. This paper illustrated the structure characters of lycopodine-type, lycodine-type, fawcettimine-type and miscellaneous group, common four types of Lycopodium alkaloids. Pharmacological studies showed HA was a potent, high selective, and reversible acetycholinesterase(AChE) inhibitor. The structure-activity relationship studies on HA disclosed that HA possesses a concise structure, in which most of structure fragments, such as two double bonds, pyridone ring, tri-carbon bridge ring, and the N-atom of the amino group were necessary for its high anti- AchE activity. Recently, some HA Schiff base derivatives and HA-tacrine hybrids were reported that they had near or better anti-AChE activity than HA.
