Carica papaya leaf is one of the considered agricultural waste; nevertheless, this leaf has been reported to contain diverse health benefits to humans. In as much as natural-based oils are of higher demands because of their aromatherapy property, this study focused on the extraction of oil from C. papaya leaf using microwave-assisted extraction (MAE) technique. Then, the extracted oil was analysed using gas chromatography-mass spectrometry. The influences of MAE parameters which include time of irradiation, microwave power, volume of solvent, and temperature on the extracted oil were investigated. The considered parameters were time of irradiation (30–180 min), microwave power (400–700 W), volume of the solvent used (distilled water) within the range of 100 to 300 mL, and temperature (40–100 °C). The outcomes from this finding showed that time of irradiation, microwave power and volume of solvent significantly altered the oil yield from C. papaya leaves. At the apex points of the considered parameters (time of irradiation, 120 min; microwave power, 500 W; volume of solvent, 200 mL; and temperature of 100 °C); the major identified compounds were n-Hexadecanoic acid; 9, 12, 15-Octadecatrienoic acid; phytol; 9-Octadecenoic acid; 9, 17-Octadecadienal; Oleic acid; and Octadecanoic acid. Therefore, C. papaya leaf is an embodiment of oil rich in fatty acid which can be employed as aromatherapy agent.

番木瓜叶是被认为是农业废弃物之一；然而，据报道，这种叶子对人类具有多种健康益处。由于其芳香疗法的特性，在对天然油的需求量较高的情况下，本研究的重点是从番木瓜中提取油。叶片采用微波辅助提取（MAE）技术。然后，使用气相色谱-质谱法分析提取的油。研究了辐照时间，微波功率，溶剂量和温度等MAE参数对提取油的影响。考虑的参数包括辐照时间（30–180分钟），微波功率（400–700 W），所用溶剂的体积（蒸馏水）在100至300 mL范围内以及温度（40–100°C） 。该发现的结果表明，辐照时间，微波功率和溶剂量显着改变了番木瓜的油产量。树叶。在所考虑参数的顶点（辐照时间：120分钟；微波功率：500 W；溶剂体积：200 mL；温度：100°C）；鉴定出的主要化合物为正十六烷酸。9，12，15-十八碳三烯酸; 植醇 9-十八碳烯酸; 9、17-Octadecadienal；油酸; 和十八烷酸。因此，番木瓜叶是富含脂肪酸的油的实施方案，其可以用作芳香疗法剂。
