영문 초록

Fruits of 10 cultivars (‘Blue Gold’, ‘Brigitta’, ‘Coville’, ‘Duke’, ‘Nelson’, ‘North Blue’, ‘Rancocas’, ‘Sierra’, Sunrise, and ‘Weymouth’) of blueberries (Vaccinum corymbosun) were analyzed for characteristics, contents of total phenolic compounds and flavonoids and antioxidant activity in this study. Fruit weights ranged from 0.83 to 1.88 g. Total soluble solids concentration varied from 9.7 in ‘Duke’ to 16.6 ˚Brix in ‘Sierra’ with titratable acidities of 0.94 % in ‘Sunrise’ and 1.75% in ‘Brigitta’. There are relatively high contents in ‘North Blue’ (23.75 mg GAE·g-1 FW) and low contents in ‘Coville’ (17.15 mg GAE·g-1 FW) in total phenolic compounds. Contents of total phenolic compounds were high in ‘Nelson’(14.1 mg QE·g-1 FW) and low in ‘Duke’ (10.1 mg QE·g-1 FW). Analysis of antioxidant activity of blueberry fruits showed that there were high acitiviites of ABTS+ radical scavenging in ‘Rancoccas’ (82.2%), ‘Bluegold’ (79.6%), and ‘Nelson’ (77.8%), and high activities of DPPH radical scavenging in ‘Rancocca’ (76.0%), and high in hydroxy radical scavenging in ‘Nelson’ (73.0%). Quantification analysis method of qualitative data showed that ‘Bluegold’, ‘Nelson’, ‘Northblue’, and ‘Rancocas’ had high contents of phenol and flavonoid compounds, and activity antioxidants of berries. Blueberry cultivars selected by statistical quantification analysis can be utilized as valuable genetic resources for breeding of blueberry with high antioxidant activities in the future.
