摘要
目的 考察几种提取方法对山楂果中总黄酮含量的影响。方法 采用不同的提取方法获得山楂浸膏 ,经大孔吸附树脂分离提取有效成分。结果 以甲醇为溶剂 ,用索氏提取器提取经大孔吸附树脂分离 ,提取效率最高(2 .0 0 % ) ;以 6 0 %乙醇为溶剂 ,超声提取经大孔吸附树脂分离 ,提取效率较高 (1.96 % )。结论 以 6 0 %乙醇为溶剂 ,超声提取 ,经大孔吸附树脂分离 ,提取效率较高 ,且方法简便易行 ,适于大规模生产。
Objective To study the extraction methods of flavonoids from hawthorn fruits. Methods Using different methods to extract flavonoids from hawthorn fruits.Results The highest extract rate(2.00%) was got through the method of continuous distillation,then seperating different parts by adsorbent resin. Comparatively high extract rate (1.96%) was got through the method of 60% ethanol ultrasonic extract, then seperating different parts by adsorbent resin. Conclusion 60% ethanol ultrasonic extract then seperating different parts by adsorbent resin is a good method to get flavonoids from hawthorn fruits.
