Optimal extraction, purification and antioxidant activity of total flavonoids from endophytic fungi of <i>Conyza blinii</i> H. Lév

Abstract

The result indicated using macroporous resin in the extraction of total flavonoid from endophytic fungus is better than organic solvents with higher extraction ratio, safety and lower cost. In vitro testing indicated that the flavonoid extracted by macroporous resin have good antioxidant activity, providing more evidence for the production of flavonoid by biological fermentation method.
