Abstract
Total polyphenol from herba artemisiae scopariae was extracted by ultrasound extraction method.Influence of extraction solvent concentration,material-solvent ratio,extraction temperature and time on extraction rate of total polyphenol was researched.The results showed that when using 60% ethanol as solvent,the material-solvent ratio was 1 ∶10(m/V),temperature was 70 ℃,the ultrasonic extraction 100 min,the extraction yield of total polyphenol was 0.503 6%.
