| Abstract: | Surfactant assisted microwave extraction of total flavonoids from Microcos paniculata was investigated.The effects on the extraction with surfactant kinds,surfactant concentration,solid to liquid ratio,microwave radiation time,and pH of solution were discussed.Results of orthogonal rotation design indicated that the optimum conditions were as follows:sodium dodecyl sulfate(SDS),suitable surfactant for extraction of 0.12%,solid to liquid ratio of 1∶35 g/mL,microwave extraction time of 2.5 min,and pH=5.5.Under the conditions,the maximum yield of flavonoids could reach 11.33%.Compared with other extraction methods,surfactant assisted microwave extraction of total flavonoids from Microcos paniculata had advantages of energy-efficient and high extracting objective constituent yield. |
