Neuroprotective effects of total alkaloids fraction of Huperzia serrata on scopolamine‐induced neurodegenerative animals

Phytotherapy Research, 2022
Huperzia serrata contains Huperzine A (HupA)—an alkaloid used to treat cognitive dysfunction. In this study, we used the total alkaloids (HsAE) to investigate their potential in managing cognitive impairment in comparison with HupA.
