Kaempferol 7-O-glucoside is a flavonol glucoside. It can be found in Smilax china,^[1] and in the fern Asplenium rhizophyllum, and its hybrid descendants, as part of a complex with caffeic acid.^[2]

Derivatives

Amurensin is the tert-amyl alcohol derivative of kaempferol 7-O-glucoside. 6'''-O-acetyl amurensin is found in the leaves of Phellodendron japonicum.^[3]
