Herbals and botanicals contain a variety of bioactive compounds that have purported health‐enhancing properties. Spices are a variety of herbs that are common to US diets and are generally overlooked with regards to health impact. In this study, the phenolic content of arnica flower (Arnica montana L.) was identified using high‐performance liquid chromatography‐electrospray ionization‐mass spectrometry (LC‐DAD‐ESI/MS). A total of eight glycosylated flavonols and 27 hydroxycinnamates were identified. Among them, six flavonoids and nine dicaffeoylqunic acids were unambiguously identified. The remaining compounds were provisionally identified by their UV and MS data. This is the first report of the existence of four flavonol glucuronides and fifteen hydroxycinnamates in arnica flowers. The caffeoylquinic acids isolated from honey suckle flowers and characterized by Ms and NMR were used to identify those in the arnica flowers and in artichoke for the first time. These results demonstrate the variety of phenolic compounds found in a single spice and illustrate the potential of spices, in general, to impact human health as a result of their bioactive constituents.
