Abstract
A new acylated flavonol glucoside was isolated from the fronds of a Philippine Pterophyta species, Cyathea contaminans COPEL. (Cyatheaceae) and chemically characterized as kaempferol-7-(6"-succinyl)-glucoside. This is the first report of s succinyl ester of a flavonoid glycoside and this compound was named pteroflavonoloside. The distribution of pteroflavonoloside in 57 species of 11 genera belonging to the three representative families of pterophyta is also discussed from the viewpoint of chemotaxonomy and biochemical systematics.
