In this study, the contents of total phenols and total anthocyanins in blue honeysuckle fruit from six regions (Jiagedaqi, Xinlin, Hongwei, Amur, Tuqiang and Tahe) of the Greater Khingan Mountains were determined and compared, the antioxidant capacity of phenols from blue honeysuckle fruit was comprehensively analyzed using three different methods, and the hypoglycemic activity was evaluated by measuring its half maximal inhibitory concentration (IC50) against α-amylase and α-glucosidase. The crude extract rich in polyphenols were separated and purified, and the resulting fractions were analyzed qualitatively and quantitatively. The results showed that the contents of total phenols and total anthocyanins in blue honeysuckle fruit from these six regions differed significantly, but the compositions were basically the same and all phenolic extracts had high antioxidant capacity. They had inhibitory activity against α-amylase and α-glucosidase, indicating the potential of blue honeysuckle fruit from these six regions for development and utilization.
