| 摘要 | [Objectives] This study was conducted to investigate the extraction process, content determination, and antioxidant properties of flavonoids from Hylocereus undatus (Haw.) Britton & Rose. [Methods] Using H. undatus as the raw material, the effects of ethanol concentration, ultrasonic temperature, time, and solid-to-liquid ratio on the total flavonoid yield were investigated through single-factor and orthogonal experiments. [Results] All factors had a significant effect on the yield. The optimized conditions were determined as follows: ethanol concentration 75%, ultrasonic temperature 60 ℃, ultrasonic time 30 min, and solid-to-liquid ratio 1:50 (g/ml). Under these conditions, the total flavonoid yield reached 3.08%. Evaluation of antioxidant activity revealed that the extract exhibited superior scavenging rates against both DPPH and hydroxyl radicals compared with the standard reference compound BHT. [Conclusions] This study holds significant importance for elucidating the pharmacological mechanisms of flavonoids in H. undatus and for expanding their application in medicine and health products. |
