▎ 摘  要

NOVELTY - Extraction method of the total flavonoids of Artemisia subdigitatacomprises (S1) crushing A.subdigitataand mixing with ethanol solution and magnetically immobilized cellulase to obtain A.subdigitatasolution, (S2) placing the A.subdigitatasolution into a high-voltage pulsed electric field and extracting for 10-20 minutes at an intensity of 45-50 kV/cm, a pulse width of 60-80 μs and a pulse frequency of 1200-1400 Hz to obtain an extract and (S3) filtering the extract and performing ultrafiltration to obtain the total flavonoids of A.subdigitata. USE - The method is used for extracting total flavonoids of Artemisia subdigitata. ADVANTAGE - The method improves the extraction rate of the total flavonoids of A.subdigitata.
