Abstract
Low aromatic curcumin extraction methods as the study based on solvent choice,extract time and solvent volume for the experimental conditions,researched the method of solvent extract of curcumin in ultrasonic field and volatile oil of the best conditions.Ultraviolet spectrophotometry and gas chromatographic analysis of laboratory test results,and observed under electron microscope before and after ultrasonic curcuma cell morphological changed,to determine effects of ultrasound on the experimental.Extracted volatile oil first,than to extract curcumin,again extracted curcumin first,than to extract volatile oil,the volatile oil yield was high by more than 36.1％,up to 1.21g/h,and a higher yield of curcumin by more than 361.4％,to 0.787mg/h.With curcumin as the target product,used petroleum ether as extract agent,with volatile oil as the target product,better used ethyl ether as extract agent.Extract volume increased with time and solvent volume improved.Ultrasonic destructed the cell walls and fiber of curcuma for target extracted better,the study on extracted low aromatic curcumin technology,so that it could be more widely used in cosmetics,food and other areas.关键词
