Calophyllum inophyllum, seed oil, ultrasonic-assisted extraction, optimizationAbstract
Calophyllum inophyllum (C. inophyllum) is a plant known as “Penaga Laut†in Malaysia. Its seeds contain valuable oil that serve as a potential alternative sources for vegetable oil. In this study, C. inophyllum seeds oil was extracted using an ultrasonic-assisted extraction (UAE) technique. The optimization of extraction parameters namely different types of solvent, extraction time, ultrasonic power, extraction temperature and liquid to solid (L/S) ratio were performed using one-factor-at-a-time (OFAT) method. The optimum extraction conditions obtained were n-hexane as a solvent, extraction time 20 min, ultrasonic power 210 W, extraction temperature 40°C and L/S ratio 20 ml/g, with an oil yield 55.44 ± 0.53 %.
