From the fronds of the following ferns the flavonoid compounds, including three new glycosides, were isolated and their structures elucidated by chemical and spectroscopic methods. From Brainea insignis J. SM. a new flavonol acylglycoside kaempferol 3-O[2-O-(6-O-caffeoyl)-β-D-glucopyranosyl]-β-D-galactopyranoside (I), from Thelypteris palustris SCHOTT a new flavanone glycoside (2S)-5,7-dihydroxy-6-methylflavanone 7-O-β-D-glucopyranoside (II), cryptostrobin ((2S)-5,7-dihydroxy-8-methylflavanone), kaempferol 3-O-β-D-glucopyranoside and kaempferol 3-O-β-rutinoside and from Adiantum malesianum GATAK. a new flavonol glycoside kaempferol 3-O-α-D-galactopyranoside (III), vitexin, isovitexin, hyperin (quercetin 3-O-β-D-galactopyranoside) and kaempferol 3-O-β-D-galactopyranoside were isolated.
