Study on microwave extraction of anti-gout active substance from corn silk

More Information
  • Received Date: March 07, 2013
  • Anti-gout active substance from corn silk was carried out using microwave extraction.The Quadric Regression Orthogonal Rotary Test was employed to screen the key factors which would affect the extraction yield and the inhibition ratio of the anti-gout active substance from corn silk.Key factors were the concentration of ethanol, the microwave extracting power, the irradiation time and the liquid-solid ratio.The optimized condition within the experimental range of the variables studied were: microwave of 600W, ethanol concentration of 70%, irradiation time of 10min and the solvent to material ratio was 20∶1 (mL /g) .Under this condition, the extraction yield of flavonoids was 26% and the enzyme inhibition ratio was 39%.
