摘要
试验以经过超微粉碎后的荷叶为原料,研究了超微粉碎对荷叶中黄酮类物质提取的影响。结果表明:在荷叶超微粉碎粒度D50为72.5μm,提取温度为80℃,提取液乙醇体积分数为70%,料液比(g∶mL)为1∶30的条件下回流提取25min,荷叶黄酮的提取率最高为6.71%,提取效率为98.24%。
The effect of super fine crushing on the extraction of flavonoids in lotus leaf was studied in this paper. The results showed that the optimum extraction conditions were： size ot material D50-72.5μm, the extraction temperature - 80℃ , ethanol concentration - 70 %, solid/liquid ratio - 70 %, and the extraction time - 25rain respectively. The yield of the flavonoids was 6.71% and the extraction efficiency was 98.24%.
