Staurogyne stenophylla (Hemsl.) C. B. Clarke ex S. Moore (S. stenophylla) has long been recognized in traditional folk medicine for its anti-inflammatory properties. However, its specific bioactive components and underlying molecular mechanisms remain unclear, which limits its scientific application as a novel anti-inflammatory feed additive for livestock and poultry. This study employed ultra-performance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS) to characterize the che
