摘要
采用体积分数60%(pH3.0)的乙醇在恒温水浴(40℃)条件下提取圣云蓝莓花色苷,将所得浓缩液经AB-8大孔树脂纯化,40℃减压浓缩,真空干燥得到紫黑色粉末,再经过制备型高效液相色谱分离获得单体化合物。经紫外光谱、红外光谱、质谱、1H和13C核磁共振、薄层色谱对单体化合物进行结构鉴定,确定此化合物为锦葵色素-3-半乳糖苷。
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.
