Huperzia continentalis (Lycopodiaceae), a New Species of Gemmiferous Firmoss Separated from Huperzia haleakalae

Systematic Botany, 2016
A new species of gemmiferous clubmoss, Huperzia continentalis, is described. This species is most abundant in northwestern North America, but also occurs in Greenland, northern Europe, and northeastern Siberia. Material of this species was previously treated as Huperzia haleakalae, but detailed morphological study shows that the species differ by color,

Comparative pan-genome analysis of Huperzia and Phlegmariurus and transcriptomics reveals thermal adaptation in Huperzia

Functional & Integrative Genomics
Huperzia and Phlegmariurus are ancient genera within the Lycopodiaceae family with significant medicinal value and ecological adaptability, yet the evolutionary dynamics and genetic diversity of their chloroplast genomes remain poorly characterized.

Anticholinesterase activity in an alkaloid extract of Huperzia saururus

Phytomedicine, 2004
Huperzia saururus (Lam.) Trevis. (Lycopodiaceae) is used widely in Argentinian traditional medicine as an aphrodisiac and for memory improvement. An aqueous extract from the aerial parts was obtained by decoction, revealing the presence of alkaloids, among other constituents. By partition with organic solvent in alkaline media, alkaloids were extracted

New Epoxyserratanes from Huperzia serrata

Planta Medica, 2003
Three new serratane-type epoxytriterpenoids were isolated from the whole plant of Huperzia serrata. The structures of these new compounds were characterized as 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21 beta-ol (1), 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21alpha-ol (2), and 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21alpha-ol-3 beta-O ...
