## Abstract In our chemotaxonomic investigation of pharmaceutically relevant __Crataegus__ species, the qualitative and quantitative flavonoid fingerprint of __Crataegus monogyna__ and __C. pentagyna__ is presented. Six flavonoids were identified as vitexin‐2″‐__O__‐rhamnoside (**1**), vitexin (**2
