Title: Effects of the Extraction Rate of Multi- component in Chuju by Different Concentrations Ethanol
Abstract: To investigate the effects of the extraction rate of multicomponent in Chuju by different concentrations ethanol,through using the ultrasonic method,the extraction conditions was 70℃ extraction temperature,30min extraction time,extraction 3times,1 ∶ 30 dosage liquor ratio,200W hypersound power. The compositions were detected by UV- visible spectrophotometry. The result showed that the optimum extraction solvent of extraction yield is 60% alcohol( 47. 52%),the optimum extraction solvent of total flavonoids is 70% alcohol( 10. 86%), the optimum extraction solvent of total polyphenol is 80% alcohol( 3. 02%),and the optimum extraction solvent of total sugar is water solution( 4. 27%). Ethanol concentrations on the extraction rate of different components of Chuju have a certain influence.
