Extraction of Solanesol by Ultrasonic-microwave Synergistic Saponification Method

Ultrasonic-microwave synergistic saponification technique was applied to extract solanesol.The effects of main factors on saponification reaction were discussed and the optimum saponification conditions were as followed:the saponification time was 60 min,the microwave power was 40 W,the mass ratio of sodium hydroxide to tobacco extract was 1∶2,and the ultrasonic was turned on.The results showed that under the optimized condition,the recovery rate of solanesol was 126.3%.Compared with other saponification methods,the ultrasonic-microwave synergistic saponification technique was a better method for solanesol extraction with less time and higher recovery rate of solanesol.
