摘要
为从闹羊花中提取总黄酮,采用正交试验法研究闹羊花总黄酮的提取工艺,考察了浸提用醇的体积分数、浸提时间、浸提次数、液料比4个因素对闹羊花总黄酮提取率的影响.确立了闹羊花总黄酮最优提取条件为:70%乙醇溶液作溶剂;液料比25∶1;浸提2次,每次30min.
The extracting condition on flavonoids from Rhododendron molle was optimized by orthogonal test design methods and UV--spectrophotometry was used for the determination of flavonoids. Effects of ethanol contents, extraction time, extraction times and ratio of liquid to material on flavonoids contents were investigated. The optimum extracting conditions were 70% alcohol as solvent, ratio of liquid to material 25：1, extracting times 2, each extracting time 30min.
