Jointfir
Gnetum
Gnetum is a plant traditionally unrecorded in specific medicinal practices. The species Gnetum parvifolium has shown potential for its stilbene enantiomers, (±)-Gnetuparin A, which exhibit xanthine oxidase inhibitory activity, though the evidence is limited and inconclusive. Similarly, Gnetum gnemon demonstrates unique physiological behavior with negative gravitropism due to tensile stresses generated by reaction wood and phloem with G-fibers, similar to some angiosperms. Both nanoextract and conventional extract of Gnetum africanum have been noted for increasing SIRTUIN-1 expression in cells, though the strength of evidence is still being evaluated. The nutritional value of Gnetum species, particularly Gnetum africanum from the Congo Basin, has been highlighted due to its high protein, mineral, and vitamin content. Safety concerns are minimal with no major issues recorded, and there are currently no reported drug interactions associated with these plants.

What the science says
- The study identified (±)-Gnetuparin A as a pair of stilbene enantiomers with xanthine oxidase inhibitory activity from Gnetum parvifolium.
- G. gnemon shows negative gravitropism due to tensile stresses generated by reaction wood and phloem with G-fibers, mechanisms similar to some angiosperms.
- The study found that Gnetum africanum and other indigenous leafy vegetables from the Congo Basin have high nutritional density with significant protein, mineral, and vitamin content.
- Both nanoextract and conventional extract significantly increased SIRTUIN-1 expression in cells, with the nanoextract showing enhanced pharmacokinetic parameters.
- Isorhapontigenin reduced airway inflammation and oxidative stress, alleviating allergic asthma symptoms in mice.
