Abstract: The authors investigated the effect of ethanol solution concentration,microwave power,microwave irradiation time,ratio of material to solvent,and temperature on Spiranthes lancea polyphenols extraction ratio applying microwave assisted method.Spiranthes lancea polyphenols extraction process was optimized by response surface analysis methods and the experimental results was analyzed on the basis of  varaiance analysis.Results showed that with ethanol concentration at 47%,temperature under 48℃,Spiranthes lancea polyphenols extraction ratio reached 0.551% in 84 minutes.

Key words: response surface method, Spiranthes lancea polyphenols, microwave assisted extraction
