Infraspecific Variation of Huperzine A and B in Icelandic Huperzia selago Complex [PDF]

open access: yesPlanta Medica, 2018
AbstractThe alkaloids huperzine A and huperzine B were originally isolated from the Chinese club moss Huperzia serrata. They are known inhibitors of acetylcholinesterase, and especially huperzine A shows pharmaceutical potential for the treatment of Alzheimerʼs disease. Its supply heavily relies on natural plant sources belonging to the genus Huperzia,

Valorization of Ficus carica Pruning Residues as Selective Botanical Insecticides: Optimized Furanocoumarin Extraction, Efficacy Against Neotropical Stink Bugs, and Mechanistic Insights via Molecular Docking. [PDF]

open access: yesArch Insect Biochem Physiol
Optimized extracts from Ficus carica pruning waste exhibit strong biological activity against major stink bug pests. Complementary in silico analyses suggest this efficacy relies on pest‐specific acetylcholinesterase inhibition, predicting a promising, pollinator‐safe alternative for sustainable agriculture.
