摘要
以小蓟为原料,采用微波辅助法提取绿原酸。在单因素试验的基础上,以液料比、微波功率和提取时间为试验因素,以小蓟中绿原酸得率为响应值,利用响应面分析法,确定了绿原酸提取的最佳工艺参数为液料比26︰1(m L/g)、微波功率550 W、提取时间95 s,在此条件下从小蓟中提取绿原酸的得率为2.81%,与预测值接近。
Response surface methodology was used to optimize the microwave-assisted extraction of polysaccharides from Cirsium setosum. The response surface method（RSM） was used to establish the extraction yield of chlorogenic acid with solid-to-solvent ratio. The optimal conditions were determined to be as followings： extraction time of 95 s, microwave power of 550 W and liquid-to-solid ratio of 26︰1（mL /g）. Under these conditions, the actual extraction yield of polysaccharide was 2.81%, which was close to the predicted value.
