红景天中黄酮类化合物的微波提取工艺优化OACSTPCD
The.Extraction Conditions of Flavonoids from Qinghai Rhodiola by microwave
对微波提取青海产红景天中黄酮类化合物的工艺进行了优化,考察了提取时间、微波功率、乙醇浓度、固液比和加热温度对提取红景天中黄酮类化合物含量的影响.结果表明:当微波提取时间为4 min,微波功率为600 w,乙醇体积分数为70％,固液比为1∶40,加热温度为80℃时提取液黄酮含量最高,为2.68％.
Flavonoids fromrhodiolawere extractedby microwave,theConditions of time、power、concentration of ethanol、silid to liquid and temperature by microwave were studied.The results showed that the optimum extraction of Flavolids fromrhodiola by microwave extraction method was4min,700W power,1∶ 35 of solid to liquid(W/V),70％ ethanol,extracting 4 min.The content of flavonoids was 2.68％.
