Title: T Research on the Extraction of Total Flavonoids from Broussonetia papyrifera by Microwave - assisted Extraction
Abstract: [Objective] To optimize the extraction process of total flavonoids from Broussonetia papyrifera leaves by Microwave-assisted Extraction.[Method] Single factor test was adopted to study on the effects of microwave time,microwave temperature,ethanol concentration,microwave power,solid-liquid ratio on the extraction rate of total flavonoids from B.papyrifera leaves.[Result] The optimal extraction process was selected,which was 1∶12(g/ml) solid-liquid ratio,55% ethanol concentration,15 min microwave time,450 W microwave power,60 ℃microwave temperature,and ethanol as the solvent.Under these conditions,the extraction rate of total flavonoids from B.papyrifera leaves was 79.62 mg/g.[Conclusion] This method was simple,repeatable and stable,and could be used for the extraction of total flavonoids from B.papyrifera leaves.
