Ultrasonic-assisted extraction of oil from calophyllum inophyllum seeds: Optimization of process parameters

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 40ºc and l/s ratio 20 ml/g,with an oil yield 55.44 ± 0.53 %. © 2016,penerbit utm press. all rights reserved.
