摘要
本文建立了苦瓜中苦瓜总皂甙超声波乙醇浸提快速测定方法,该法仅需样品0.1g,浸提溶剂80%乙醇2ml,浸提时间仅需30min,不需加热,降低能耗,分析测定效率提高十倍以上。测定结果与常规的乙醇回流没有显著差异。
A rapid determination of total momordicoside by ultrasonic extraction from bitter melon （Momordica charantia） was reported in this paper.In the operation of ultrasonic extraction,only O.lg of sample and 2ml of 80% ethanol were used.Only 30min was necessary for the extraction.As compared with the conventional Soxhlet＇s method,the ultrasonic extraction method required shorter extraction time, less solvent reagent and no heating. The determination efficiency of the ultrasonic method was 10 times higher than the Soxhlet, s method.There was no significant difference between the analytical results obtained by those two methods.
