Abstract: This paper reports the optimization of process conditions for the ultrasonic-assisted extraction of oil from Chirocephalus diaphanous by one-factor-at-a-time and orthogonal array design methods. Ethyl acetate was found to be the most suitable solvent for Chirocephalus diaphanous oil among 5 solvents under investigation. The optimal extraction conditions were determined as 150 W of ultrasonic power, 1:10 of material/liquid ratio (g/mL), 40 min of extraction time, and 60 ℃ of extraction temperature. Under these conditions, the oil yield was 84.83%. The ultrasonic-assisted extraction method had the advantages of time-saving extraction and better oil quality over the traditional solvent extraction method.

Key words: Chirocephalus diaphanous oil, ultrasonic-assisted extraction, physico-chemical properties
