Rhaponticin 6′′-O-gallate 

Rhaponticin 6′′-O-gallate is a stilbene glucoside gallate that can be found in rhizome of Rheum undulatum L. Rhaponticin 6′′-O-gallate inhibits nitric oxide production in lipopolysaccharide-activated macrophages^[1].

Rhaponticin 6′′-O-gallate shows inhibitory activity of NO production in lipopolysaccharide-activated macrophages, with IC₅₀ of 11-69 μM^[1].
