摘　　要：通过选择酶用量、pH值、料液比等作为考察因素,以多酚得率为指标进行正交实验.研究纤维素酶法提取雀儿舌头中多酚物质的最佳工艺条件.结果表明:在最佳工艺条件下,多酚得率达到了4.24mg/g,相比超声波法提取雀儿舌头多酚得率(3.34 mg/g),有较大提高.该工艺多酚得率高,稳定性好,对环境绿色无污染,适用于产业化.The optimum technological condition by the Cellulase Enzymatic Extraction Technology of the poly- phenols from Leptopus Chinensis （Bunge） Pojark is studied. Through the Orthogonal design, we analysed the effect of ethanol concentration, ratio of material to liquid,to the polyphenols from Leptopus Chinensis （Bunge） Pojark. The experiment result shows that compared with ultrasonic wave extraction technology on polyphenols from Leptopus Chinensis （Bunge） Pojark, this method has a greater extraction rate （4.24mg/g）. The extrac- ting technology shows higher extraction rate of polyphenols, good stability, green, no pollution, and is availa- ble for industrial production.
