Title: Research on ethanol extraction of rose pigment by ultrasonic assisted extraction
Abstract: The ultrasonic assisted extraction(UAE) being used for rose pigment extraction from deoiled roses was investigated.The optimum technological conditions were obtained by single-factor and orthogonal experiments as ethanol solution concentration 65%(V/V)(pH=1),the ratio of material to solvent 1∶20(m∶V),ultrasonic power 400 W,the temperature 70 ℃ and the extraction time 120 min.Under these conditions,the maximum OD value of the pigment was obtained.
