title: Phenolic compounds from Selaginella moellendorfii.
abstract: Chemical investigation of the leaves and roots of Selaginella moellendorfii Hieron has resulted in the isolation and characterization of two new flavone glucosides, 7-O-(β-glucopyranosyl(1→2)-[β-glucopyranosyl(1→6)]-β-glucopyranosyl)flavone-3',4',5,7-tetraol (1) and 7-O-(β-glucopyranosyl(1→2)-[β-glucopyranosyl(1→6)]-β-glucopyranosyl)flavone-4',5,7-triol (2), two new biflavonoids, 2,3-dihydroflavone-5,7,4'-triol-(3'→8″)-flavone-5″,6″,7″,4'''-tetraol (3) and 6-methylflavone-5,7,4'-triol-(3'→O→4''')-6″-methylflavone-5″,7″-diol (4), two new lignans, (7'E)-3,5,3',5'-tetramethoxy-8 : 4'-oxyneolign-7'-ene-4,9,9'-triol (5) and 3,3'-dimethoxylign-8'-ene-4,4',9-triol (6), together with two known monolignans, four known lignans, and four known biflavonoids. Their structures were established by spectroscopic means and by comparison with literature values.
