• Kaempferol 3-O-[(6 ''' E-caffeoylglucosyl)-(1 -> 3)-glucoside]-7-O-glucoside
• Flavonol
• Aspleniztm altajense
• Asplenium ruta-muraria
• Aspleniaceae

A flavonoid was isolated from the fronds of Asplenizun ritta-nutraria and A. altajense (Aspleniaceae) collected in the Altai Mountains and adjacent area. The compound was identified as kaempferol 3-O-beta-[(6 ''' E-caffeoylglucopyranosyl)-(1 -> 3)-glucopyranoside]-7-O-beta-glucopyranoside (1) by UV, H-1 and C-13 NMR spectroscopy, LC-MS, and acid and alkaline hydrolyses. Another flavonoid (2) was isolated from A. allajense, as a minor compound, together with 1 and identified as deacylated compound 1, i.e. kaempferol 3-O-laminaribioside-7-O-glucoside. They were found in nature for the first time.
