Optimization of Extraction Technology of Polysaccharide from Perilla Leaf Assisted by Microwave Technology |
| |
| Abstract: | The process conditions for perilla leaf polysaccharide were studied. Perilla leaf polysaccharide was extracted by microwave-assisted. The experimental factors, such as ration of solid to solvent (g/mL), microwave power, microwave time, and load were investigated. The result showed that load had remarkable influence on the extraction rate of polysaccharide; Microwave power and microwave time had significant effect on the extraction rate of polysaccharide. The optimum extraction conditions of perilla leaf polysaccharide by microwave were obtained as follow: load 10 mL, microwave time 30 s, microwave power 800 W. Under these conditions, the extraction rate of perilla leaf polysaccharide was about 3.99%. The extraction effect of perilla leaf polysaccharide was strengthened by microwave technology. |
