Abstract

Blueberries (Ericaceae) are cultivated worldwide, and are used not only as foodstuff but also for relievement of eyestrain. Bluberry species representatively includes highbush blueberry (V. corymbosum L.), lowbush blueberry (V. angustifolium $A_{IT}$.), rabbiteye blueberry (V. ashei $R_{EADE}$), and bilberry blueberry (V. myrtillus L.). All of these species contain large amounts of phenolics and anthocyanins. In this regard, we isolated six compounds from Korea cultivated blueberry and identified as 3-O-caffeoylquinic acid (1), 5-O-caffeoylquinic acid (2), myricetin-3-O-${\beta}$-D-galactoside (3), quercetin-3-O-rutinoside (4), ethyl-3-O-caffeoylquinic acid ester (5), ethyl-5-O-caffeoyl quinic acid ester (6) by $^1H$-NMR, $^{13}C$-NMR and MS. Anti-oxidative activities of six compounds were verified by anti-oxidant assay such as DPPH, ABTS and Hypoxanthine/xanthine oxidase system. And then, anti-oxidant activities of Korea blueberry and Canadian were compared with each other. These results support that Korean blueberry has also the possibility to be potential supplementary material as healthy food like Canadian blueberry. Therefore, Korean blueberry can be used as a substitute of Canadian blueberry.
