Abstract:

The anthocyanins in St. cloud blueberry fruits were extracted with 60% ethanol (pH 3.0) at 40 ℃ and the extract was concentrated, followed by purification with AB-8 macroporous resin and vacuum drying, to obtain a dark purple powder. A monomeric compound was isolated from the powder by preparative high-performance liquid chromatography (HPLC) and identified as malvidin-3-arabinoside by ultraviolet-visible, infrared, mass and nuclear magnetic resource spectroscopy as well as thin layer chromatography. This indicates that St. cloud blueberry fruits are exploitable for further development.

Key words: St. cloud blueberry fruits, structural identification, malvidin-3-galactoside
