Study on the microwave-assisted extraction of aloe polysaccharide form aloe leaves
The extracting technology of Aloe polysaccharide from Aloe with micro wave was studied using the orthogonal test. Results of tests showed that the optimum microwave-assisted extraction conditions included: ethanol concentration of 90%, extraction time of 20 minutes, the power of microwave of 480 W, solid/liquid ratio of 1∶8. Under this conditions the extraction rate of Aloe polysaccharide was 0.0765%. Compared to traditional extraction method, this method has the advantage of simple procedure and improving extraction yield.
