摘要：Abstract Millettia speciosa (M. speciosa) Champ is a medicinal and edible plant. The roots are rich in flavonoids, which possess multiple biological activities, including lipid‐lowering effects. This study aimed to explore the effect of flavonoid‐enriched extract from M. speciosa (FMS) on obesity. The UPLC‐Q‐TOF‐MS analysis and chromatographic analysis were adopted to identify flavonoid compounds in FMS. Male C57BL/6J mice were fed with a high‐fat diet for 3 months and were then treated with FMS (50 or 100 mg/kg/d) or Orlistat (10 mg kg−1 d−1) for another 8 weeks. A total of 35 flavonoids were identified in the extract of M. speciosa root. FMS reduced body weight gain, liver weight gain, white adipose tissue, lipid accumulation, and blood glucose. The levels of TG, ALT, AST, and inflammatory‐related adipokines (TNF‐α and IL‐6) in serum were also reduced by FMS. In addition, FMS promoted thermogenesis in brown adipose tissue and induced the activation of lipolysis, fatty acid oxidation, and oxidative phosphorylation in white adipose tissues. In summary, long‐term administration of FMS could ameliorate high‐fat diet–induced obesity by stimulating adipose thermogenesis and lipid metabolism.
