Summary The ginkgo biloba extract ( GBE ) nanoparticles were successfully prepared by adopting the liquid anti‐solvent precipitation ( LASP ) method to enhance the antioxidant activity and oral bioavailability of GBE . Under the optimum preparation conditions, the particle size of GBE nanoparticles had reached 76.90 nm. Moreover, the antioxidant activity and intestinal transmittance of GBE nanoparticles were tested before and after the simulated in vitro digestion, which were both significantly higher than that of raw GBE . Significantly, the AUC ( 0→t) value of flavonoids and terpene lactones in GBE nanoparticles were 2.20 and 2.24 times of that in raw GBE , respectively. What cannot be ignored was that the residual amount of ethanol and n‐hexane meets the safety standards for food.
