| Abstract: |
| Sesamin was extracted from black sesame by ultrasound-assisted extraction method with ethanol as extraction solvent. The effects of ethanol volume fraction, solid-liquid ratio, ultrasonic power, extraction temperature and extraction time on the extraction rate of sesamin were studied by single factor experiment. The extraction process of sesamin was optimized by response surface methodology. The results showed that the optimal conditions were obtained as follows: ethanol volume fraction 60%, solid-liquid ratio 1∶ 15, ultrasonic power 300 W, extraction temperature 57.0 ℃ and extraction time 23 h. Under the optimal conditions, the extraction rate of sesamin was 0.449 6%. The study provided guidance for the development and utilization of sesamin. |
