Title: Study on microwave-assisted extraction technique of flavonoid from Ophiopogon japonicus.
Abstract: Objective:To study microwave-assisted extraction technique of flavonoids from Ophiopogon japonicus. Methods:The effect of the parameters,i.e.ratio of solid to liquid,microwave treatment time,microwave power and volume ratio of ethanol on extraction amount of flavonoid were analyzed by single factor experiment.Results:Optimum processing data were determined as follows:90.0% ethanol as extracting solvent,stock ratio 1:14(g/ml) ,microwave extracting for 4 minutes at the power of MED. The extraction rate was 39.7% higher than that of non-microwave's.Conclusion:Extraction of flavonoids by microwave from Ophiopogon japonicus is an eficient method.
