To study the chemical constituents of the herb of Antenoron filiforme.The constituents were separated by column chromatography and their structures were elucidated by spectral data analyses.Eleven compounds were isolated from the ethanol extract of A. filiforme and identified as, bronane-5-hydroxy-2-O-beta-D-glucopyranoside (I), adenosine (II), bonaroside (III), rhamnetin (IV), hyperoside (V), rhamnetin-3-O-beta-D-galactopyranoside (VI), kaempferol-3, 7-O-bis-alpha-L-rhamnopyranoside (VII), stigmasterol (VIII), nonacosanoic acid (IX), daucosterol (X), 3beta-sitosterol (XI).All compounds are obtained from A. filiforme for the first time.
