BACKGROUND
Huperzia squarrosa (Forst.) Trevis is used in traditional medicine for improving memory deficits. Alkaloids, triterpenoids, flavonoids are main bioactive compounds of Huperzia squarrosa (Forst.) Trevis.
OBJECTIVE
This study aimed to investigate the antioxidant, AChE inhibitory activities

Huperzine A is a natural cholinesterase inhibitor derived from the Chinese herb Huperzia serrata. There is evidence that huperzine A may compare favorably in symptomatic efficacy to cholinesterase inhibitors in use. In addition, huperzine A has antioxidant and neuroprotective properties that suggest
Potent effects of alkaloid-rich extract from Huperzia selago against sodium nitroprusside-evoked PC12 cells damage via attenuation of oxidative stress and apoptosis.

Huperzine A (HupA), derived from Huperzia Serrata, has exhibited a variety of biological actions, in particular neuroprotective effect. However, the protective activities of HupA on murine embryonic fibroblast NIH3T3 cells after X-rays radiation have not been fully elucidated. Herein, HupA treatment

Acetylcholinesterase (AChE) inhibitors have been used for the symptomatic treatment of Alzheimer's disease. Eleven whole plants from Panama belonging to the Lycopodiaceae family have been screened for their anticholinesterase inhibitory and antioxidant activities by a thin-layer chromatography (TLC)
