摘要
为研究大高良姜活性成分,选用纤维素酶法提取大高良姜黄酮,并选取酶添加量、酶解时间、酶解温度和酶解pH值4个因素进行单因素试验,在此基础上以4个因素为自变量,提取率为响应值,采用Box-Behnken试验设计和响应面分析法,建立数学模型确定大高良姜黄酮提取的最佳工艺条件为酶添加量30.0U/mL、酶解温度56.6℃、pH5.14、酶解时间1.71h,在此条件下,大高良姜总黄酮的提取率为5.08%。
The cellulose-assisted extraction of flavonoids from galangal rhizomes（Alpinia galanga） was optimized by response surface methodology based on Box-Behnken design.The extraction efficiency of flavonoids was investigated with respect to four variables including enzyme dosage,hydrolysis time,temperature and pH,and a mathematical model was developed.The optimal enzyme dosage,temperature,initial pH and time for extracting flavonoids from galangal rhizomes were 30.0 U/mL,56.6 ℃,5.14 and 1.71 h,respectively.The extraction yield of flavonoids under these conditions was 5.08%.
