| Abstract: | Ultrasonic-assisted extraction method was used to investigate the extraction of flavonoids from loquat flower.The method of response surface analysis with four factors and three levels was adopted to optimize the extraction conditions of flavonoids on the basis of single-factor experiment.The results showed that optimal conditions for extraction of flavonoids could be reached using 64% ethanol as extraction solvent with solid and liquid ratio 1∶ 44(g∶ mL)at 59 ℃ for 38 minutes.Under these conditions,the yield of flavonoids from loquat flower was 106.422 mg/g. |
