Chemical compound
Rhaponticin is a stilbenoid glucoside compound. Its aglycone is called rhapontigenin . It can be found in rhubarb rhizomes .[ 1]
It has beneficial effects on diabetic mice,[ 1] and in vitro results suggest it may be relevant to Alzheimer's disease with an action on beta amyloid .[ 2] It is a phytoestrogen and has estrogenic activity.[ 3] [ 4]
