摘  要:
以新疆昆仑山产雪菊为原料,采用水作为萃取剂提取黄酮类化合物,研究提取温度料液比、提取时间和粒度大小4因素对生物黄酮含量的影响,进行响应面试验设计分析。以黄酮类化合物含量为指标,通过响应面法对提取工艺条件进行优化,最终确定水溶液萃取法提取黄酮的最优条件为提取温度90℃、料液比1:90(g/mL)、提取时间60min、粒度40目,在此条件下昆仑雪菊的水溶性黄酮含量为24.85%。

摘  要:
Response surface methodology(RSM) was applied to optimize the extractions of water soluble flavonoids from Coreopsis tinctoria flowers using water as the extraction solvent.The effects of extraction temperature,material/liquid ratio,particle size and extraction time on the extraction efficiency of water soluble flavonoids were investigated.The optimal extraction conditions were extraction temperature of 90 ℃,material/liquid ratio of 1:90,extraction time of 60 min and raw material particle size of 40 mesh.The actual extraction rate of flavonoids from Coreopsis tinctoria under the optimal extraction conditions was 24.85%,which was close to the predicted value.
