| Abstract: | The extraction technology of flavonoids antioxidants in Protulaca Oleracea L was studied in this paper. Ethanol was used as extracting alcohol, together with the treatment of supersonic wave during extraction. According to a L 9(34) orthogonal experiment, the optimal condition of extraction was obtained as follows: 60% alcohol as solvent, solid/liquid ratio being 1:40, supersonic wave treatment of 30 min at 60℃, and the extraction being repeated for three times. |
