Objective: To study the chemical constituents of the herb of Antenoron filiforme.
Methods: The constituents were separated by column chromatography and their structures were elucidated by spectral data analyses.
Results: 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).
Conclusion: All compounds are obtained from A. filiforme for the first time.
