| Abstract: | Extraction technology of flavonoids from cactus with ultrasonic wave was checked and modified in the study.As a result,the optimal condition were as follows:extraction solvent was 80% ethanol,extraction time was 20 min,ratio of solvent to material was 10:1,the best extrac- tion yield was 323.81 mg/100g.The result showed that this process have value of high yield,low extraction temperature and less time. |
