| Abstract: | This paper compared the result of heat heat circum-fluence extraction with that of microwave-assisted extraction of Salidroside from Rhodiola crenulata .The optimum extraction conditions are compared and fixed on by using single factor and orthogonal test. Conclusion: The optimum extraction conditions of microwave-assisted extraction are ethanol solution of 95 % ,liquid-solid ratio of 1:20,microwave power of middle frequency, extraction time of 30 seconds, and extraction degrees of 2 ,respectively. There is obvious difference on the extraction rate and extraction time between microwave-assisted and heat circum-fluence ways , microwave-assisted extraction rate are apparently 40 % better than heat circum-fluence extraction, the taken time is also curtailed greatly. |
| Keywords: | Rhodiola crenulata effectual ingredient salidroside microwave-assisted extraction |
