Abstract:To promote the release of polyphenols from Lonicerae japonica（L.japonica）and improve the antioxidant and antiallergic abilities of L.japonica，Aspergillus niger（A.niger）was used to treat L.japonica by solidstate fermentation.The results showed that six days were the optimal fermentation time based on the contents of total polyphenols and flavonoids.The fermentation process lasted for six days，and the DPPH·scavenging rate increased from 61.25% to 84.57%；the·OH scavenging rate increased from 23.43% to 30.10%；the ABTS+·scavenging rate increased from 32.09% to 55.06%，and the total reducing power increased from 0.730 9 to 0.826 9.The inhibition rate of hyaluronidase increased from 13.51% to 64.86%.The content of total polyphenols increased from 76.60 mg/g to 97.56 mg/g；the content of total flavonoids increased from 20.76 mg/g to 24.12 mg/g，and the content of total saponins increased from 3.50 mg/g to 4.26 mg/g.Meanwhile，the highest activities of cellulase，β-glucosidase，and xylanase produced by A.niger were 11.70，15.78，and 32.39 IU/g，respectively.This study showed that the solid-state fermentation of L.japonica by A.niger could promote the release of polyphenols in L.japonica.
