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[edit]

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]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
