To optimize the extract technology of flavonoids for Plumula Nelumbinis. Five methods such as alkali-solution and acid-isolation method, water extraction,ethanol extraction, microwave-assisted ethanol extraction , ultrasonic-assisted ethanol extraction were used to extract flavonoids for Plumula Nelumbinis and also compared and analyzed the flavonoids by adopting the total content of flavonoids and the yield of dry extract as markers.The comprehensive values Y was calculated.Through the comprehensive evaluation of the two markers ,the comprehensive values Y ranked in the order of microwave-assisted ethanol extraction ,ultrasonic-assisted ethanol extraction, ethanol extraction,water extraction,alkali-solution and acid-isolation method. Microwave-assisted ethanol extraction is the optimal method to extract flavonoids for Plumula Nelumbinis.
