Objective To optimize the extraction technology of flavonoids from Pyrrosia gralla.Methods Extract flavonoids from Pyrrosia gralla by Soxhlet extraction with ethanol as solvent .Based on single factor test ,orthogonal test was adopted to optimize extraction technology by taking extraction temperature ,extraction time,ethanol concentration and solid-liquid ratio as factors.UV was used to determined the content of flavonoids from Pyrrosia gralla.Results ptimum extraction technology was as followng:extracted 5 h with 30 times,the amount of 80%ethanol,liquid to solid ratio:1∶30 at 100 ℃.Extraction rate of total flavonoids was up to 4.02% on this condition.Conclusion This method is stable,economical,easy and higher extraction rate and can be used as the best extraction for Pyrrosia gral-la.
