【摘要】 利用微波提取花生壳中总黄酮类化合物.在单因素试验的基础上,采用响应面法研究微波提取的最佳工艺条件.结果表明,以80%的乙醇为提取溶剂,微波提取最佳条件为:微波功率510 W、提取时间12 min、液固比32∶1(mL/g);在此最佳工艺条件下,花生壳总黄酮得率为2.385 mg/g.更多还原

【Abstract】 We carried out the extraction of total flavones from peanut hull by microwave-assisted extraction,and studied the optimal extraction conditions,such as microwave power,extraction time and liquid-to-solid ratio,by response surface analysis(RSA) based on single factor tests.The results show that the optimal extraction conditions are as follows in the presence of 80% ethanol as solvent,microwave power 510 W,extraction time 12 minutes and liquid-to-solid ratio 32∶1 mL/g.Under the optimal conditions,the yield of total flavones from peanut hull reached 2.385 mg/g.更多还原
