| Abstract: | The extraction conditions of mimosa flavonoids were optimized by orthogonal test experiment using microwave assisted extraction,the separation,purification and characterization of the flavonoids were also processed.Results showed that the optimal experimental conditions were the microwave power of 450 W,microwave extraction time of 4min,solid-to-liquid ratio of 1∶50g.mL-1,with the extraction yield of the mimosa flavonoids of 8.66mg.g-1.By spectra analysis and determination,the mimosa flavonoids extracted was 7,8,3′,4′hydroxy 6-Cα-L-a rhamnose(1→2)]-β-D-glucose carbon flavonoid glycosides,that is C27H30O15. |
