Abstract: The use of ultrasonic-assisted solvent extraction of lutein from flower of marigold ( Tagetes erecta Linn.) under different operating conditions was studied. Influences of solvent, ratio of material to liquid, ultrasonic power and ultrasonic treatment time on the extraction yield of lutein were studied. It was found that both n-hexane and petroleum ether were good solvent forultrasonic-assisted process. Optimal ultrasonic-assisted n-hexane and petroleum ether extraction conditions for 1.000 g marigold flower powder were: 1:20(g::mL) for ratio of material to liquid, 30 min for ultrasonic time, 300 W and 400 W for ultrasonic power, and extraction rates were 93.65% and 98.77%, respectively.

Key words: lutein, ultrasonic-assisted extraction, marigold (Tagetes erecta Linn.)
