摘  要:
Using ethanol as solvent,flavonoids were extracted from Gynura divaricata( L.) with the assistance of microwave.The experiment obtained the optimum extracting technology:presoaking in 70% ethanol for 30 min,the ratio of solid material to liquid was 1∶ 30;microwave acting under 630W microwave for 30s.The extraction rate of flavonoids reached to 94.7% with the optimum extracting conditions,the total flavonoids content was 2.985% in leaves.
