Study on the Ethanol Extraction of Total Flavonoids from Sweet Potato Stem and Leaves |
| |
| Abstract: | On the basis of single factor experiment, extraction of total lfavonoids using the ethanol from stems and leaves of was studied, through the orthogonal experiment. The results showed that the ultrasonic and ethanol immersion extraction was used to extract the optimum extraction condition of total flavonoids from stems and leaves of sweet potato is:70 ℃ ultrasonic extraction temperature,80% volume fraction of ethanol,liquid material ratio 1 ∶ 40 and 30 h ultrasonic extraction time. Under the optimum conditions, the total lfavonoids extraction rate of sweet potato stem and leaf was 0.831 6%. |
