Abstract
The celexy which is of low price and high yield is used as raw material and organic solvent re -fluxing extraction technique of flavonoids from celexy leaves are discussed .The effect of extraction solvent , ex-traction concentration , solid to liquid ratio , extraction temperature , extraction time on extracting the flavonoid was investigated .Moreover on bases of this , with orthogonal experiments , the optimal condition are obtained . The experimental results showed that dry celery leaves as raw material , the extraction flavonoids'best techno-logical conditions are as follows:extraction agent is ethanol , extractant concentration is 80%, the solid to liq-uid ratio is 1∶30 , extraction temperature is 85 ℃and extraction time is 60 min.In these conditions , the yield of flavonoids may reach around 2.43%.Through orthogonal test , the concentration of alcohol have greatly ef-forts on the extraction rate .关键词
