Optimization on the Rapid Extraction Process of Polyphenols from Phyllanthus emblica L.by Response Surface Method
The flash extraction process of Phyllanthus emblica L.polyphenols was optimized using response surface methodology.In order to enhance the polyphenol yield,Phyllanthus emblica L.was employed as the raw material,with polyphenol yield as the indicator.Single-factor flash extraction experiments were conducted,varying the liquid-to-material ratio,extraction speed,extraction time,and number of extractions.The response surface methodology was employed to optimize the extraction process parameters,and to establish a regression model.The results demonstrated that the regression model effectively reflected the relationship between polyphenol yield and extraction parameters.The optimal flash extraction conditions were determined as follows:extraction speed of 6 000 r/min,liquid-to-material ratio of 66∶1 mL/g,and extraction time of 80 s.Under these conditions,the polyphenol yield of Schisandra chinensis L.reached 0.574％±0.034％,significantly higher than the yield achieved through conventional reflux extraction(0.359％±0.102％).The optimization of polyphenol flash extraction technology of Phyllanthus emblica L.is helpful to open up the development path of Phyllanthus emblica L.production,to tap the potential of exploitation and application of Phyllanthus emblica L.resources,and to provide ideas and references for the industrialization of natural functional factors.
