Enzymatic hydrolysis was performed in conjunction with high hydrostatic pressure (HPP) treatment to extract tricin from rice hull. Enzymatic hydrolysis performed with Celluclast (0.5%, w/w) prior to HPP (500 MPa) treatment yielded maximum tricin content (32.9 mg/kg rice hull). The tricin content obtained by conventional solvent extraction and HPP treatment alone were 14.7 and 19.7 mg/kg rice hull, respectively. The rice hull extract containing tricin displayed antioxidant, anti-inflammatory, and antiadipogenic activities. The efficacy of rice hull extract obtained by either HPP or combination of enzymatic hydrolysis and HPP treatments was significantly greater than that of extract prepared by traditional solvent extraction.
进行酶水解并结合高静水压（HPP）处理以从稻壳中提取小麦黄素。在HPP（500兆帕）处理之前用纤维素酶（0.5%，w/w）进行酶水解可获得最高的小麦黄素含量（32.9毫克/千克稻壳）。单独通过传统溶剂萃取和HPP处理获得的小麦黄素含量分别为14.7毫克/千克和19.7毫克/千克稻壳。含有小麦黄素的稻壳提取物具有抗氧化、抗炎和抗脂肪生成活性。通过HPP或酶水解与HPP处理相结合获得的稻壳提取物的功效明显高于传统溶剂萃取制备的提取物。
