Abstract:
In order to promote the development and utilization of berry-related products in Northeast China, 9 kinds of berries widely cultivated and common in Northeast China were used as the research objects, the contents of total phenols, total flavonoids and total anthocyanins in were determined and analyzed. The types and contents of the phenolic monomers in these berries were determined by high performance liquid chromatography. The antioxidant activity and anti-inflammatory activity of the berries were evaluated by measuring DPPH• scavenging ability, ABTS+∙ scavenging ability, hyaluronidase inhibitory ability and albumin denaturation inhibitory ability, and correlation analysis was conducted. The results showed that the contents of total phenols, total flavonoids and total anthocyanins in blue honeysuckle and lingonberry were higher, which were 2.83 and 2.42 g GAE/100 g DW, 0.99 and 2.09 g Rutin/100 g DW, 104.33 and 414.73 mg/100 g DW, respectively. These two berries had strong antioxidant and anti-inflammatory activities. The correlation results showed that the total phenolic content determined the antioxidant and anti-inflammatory activities of the berries. 19 monomer phenols were identified and quantified in 9 berries, with chlorogenic acid, cryptochlorogenic acid, arbutin and baicalein all being detected in berries. Chlorogenic acid and cryptochlorogenic acid were the main phenolic monomers in most berries. Among them, the number of the type of monomer phenol species in lingonberry and the content of the monomer phenols in blue honeysuckle were the highest. This experiment provides a theoretical basis for the comprehensive utilization of berries in Northeast China.
