Abstract:

The study’s aim was to obtain Ginkgo biloba extract with a high mass fraction of total flavonoids. On the basis of single-factor test, the sample concentration, ethanol volume fraction, eluate volume, and elution flow rate were used as the investigation factors and the mass fraction and yield of total flavonoids extracted from G. biloba were used as the investigation indicators. Box-Behnken design (BBD) and response surface method were used to optimize the column chromatography process for purifying the total flavonoids extracted from G. biloba. Optimal purification was achieved by using a sample concentration of 3.1 mg/mL, ethanol volume fraction of 71%, eluate volume of 2 BV (BV is the column void volume), and elution flow rate of 2 BV/h. Under the optimal conditions, three batches of verification experiments were conducted. The average mass fraction of total flavonoids in the G. biloba extract reached 35.77%, and the yield was 93.30%. The mass fraction of total lactones in the G. biloba extract reached the standards of The Pharmacopoeia of the People's Republic of China. Using BBD and response surface method for optimizing the column chromatography process for the purification of total flavonoids is scientific, reasonable, and feasible.This study can be used as a reference for the industrial production of total flavonoids.
