Abstract: Had studied the extraction technology purification method and structural appraisal of ginger’s flavonoid. The results showed that the best excellent condition was adopting 40multiples’ raw materials weight of 90% methyl alcohols solvent, current soaking 4h under 60~65℃. But the best combination was that adopting 40multiples’ raw materials weight of 75% methyl alcohols solvent , current soaking 2h under 60~65℃. The highest obtain rate was 1.250%. The main composition is flavanones.

Key words: ginger, flavonoid, extraction, purifition, structural appraisal
