[Objectives] This study was conducted to screen lavandulyl flavonoids with anti-inflammatory activity from Sophora flavescens. [Methods] 35 compounds were screened from traditional Chinese medicine S. flavescens using the nitric oxide (NO) anti-inflammatory activity model. [Results] Five components, 8 (xanthohumol), 13 (kurarinol), 27 (4-methoxysalicylic acid), 28 (b-resorcic acid) and 30 (b-resorcic acid), exhibited significant anti-inflammatory activity, with IC
50 values of 5.99, 4.76, 6.96, 3.41 and 5.22 μM, respectively. Especially, 8 (xanthohumol) and 13 (kurarinol) were typical lavandulyl flavonoids in S. flavescens, which were worth further exploration. Furthermore, UPLC-Q-Exactive and GNPS molecular networking technique were used for rapid analysis of lavandulyl flavonoids from S. flavescens. A total of 15 components were identified. [Conclusions] This work lays a theoretical foundation for further separation and analysis of lavandulyl flavonoids with anti-inflammatory activity from S. flavescens.
