摘要

采用物理化学分析方法对四种不同提取方法（冷水、热水、超声和超临界流体）的番木瓜叶提取物进行了表征。超声波提取粗提物的产率最高（6.76%），超临界流体提取物的产率最低（1.83%）。冷水提取物的红外光谱显示其官能团与槲皮素最相似。同样，热分析表明，冷水提取物的吸热峰与槲皮素非常相似，所得值为137°C，起始值为118°C。液相色谱（LC）图谱表明，只有冷水提取物显示出0.203ppm的槲皮素。

Physico-Chemicals Characterization of Quercetin from the Carica papaya Leaves by Different Extraction Techniques

Carica papaya leaf extracts from four different extraction methods (cold-water, hot-water, sonication and supercritical fluid), were characterized using physico-chemical analysis. Sonication extraction showed the highest percentage yield of crude extracts (6.76%) and the lowest from the supercritical fluid extraction (1.83%). The Infrared (IR) spectrum of cold-water extract demonstrated the most similarity of functional group to quercetin. Likewise, the thermal analysis indicated that cold-water extract gave a quite similar Endothermic peak to quercetin with the obtained value which was 137°C and onset value which was 118°C. The liquid chromatography (LC) profile indicated that only the cold-water extract exhibited 0.203 ppm of quercetin.
