Abstract:The extraction technology of flavonoids from Ginkgo biloba leaves was studied in this paper. When the crude leaves used the cellulase enzyme pretreatment before extraction process, the extraction yield of total flavone was up to 2.01%. The extraction conditions were also determined experimentally as following: concentration of enzyme in the liquor being 0.125 g/L, mixture ratio between enzyme and substrate being 1:1200, treating 2 hours, at 45 degrees C, under natural pH value.
Keywords:Enzymatic treatment  Cellulase enzyme  Flavonoids  Extraction process
