Objective: To explore the bioactive components of Lonicerae Japonicae Caulis and to study the phenolic acids of the plant. Method: Compounds were isolated and purified by solvent extraction ethanol extraction
repeated column chromatography on silicagel and Sephadex LH-20.Their structures were elucidated on the basis of physical characteristics and spectral data. Result: Six phenolic compounds were obtained and identified as methyl p-hydroxycinnamate (1)
ethyl caffeate (2)
methyl caffeate (3)
ferulic acid (4)
caffeic acid (5)
and chlorogenic acid (6). Conclusion: Compounds 1
3 and 4 were isolated from Lonicerae Japonicae Caulis for the first time.
