[Study on microwave extracting process of polysaccharide from Euonymus fortunei].
OBJECTIVE
To study the best extraction process of the polysaccharides from Euonymus fortuei with microwave.


METHODS
The orthogonal experiment was used to investigate 4 influential factors: the ratio of solid to liquid (A), microwave power (B), extraction time (C), the times of extraction (D).


RESULTS
The optimal conditions were A1B1C3D3 as the microwave power was 30W, the ratio of solid to liquid was 1:50, the time of extraction was 14 min, and extracting for 4 times. The extraction yields of polysaccharide from Euonymus fortunei was 10.56%.


CONCLUSIONS
The microwave can be used in the extraction of the polysaccharides from Euonymus fortunei for shorter time and less energy.
