The results showed that optimum extraction conditions were 80.00%, 30 ∶ 1(ml/ g),55.40minand64.19℃ forethanolvolumefraction,ratioofliquid-to-solid,extractiontimeandextraction temperature,respectively.Undertheseconditions,thepredictedandactualextractionratesofflavonoidfromPortulaceoler- acea L. were 1.42% and 1.38%,respectively. The predictive value of the regression model agreed with the experimental value,and the optimized conditionsfor flavonoid extraction fromPortulace oleracea L. were reliable. Key words: Portulace ol
