Analysis of Anthocyanins Components of 11 Blueberries in Yunnan Lijiang and Jilin Jingyu

The anthocyanins components of 11 blueberries in Yunnan Lijiang and Jilin Jingyu were determined by HPLC. The regression equation of the concentration of delphinidin-3-galactoside, delphinidin-3-glucoside, cyanidin-3-galactoside, cyanidin-3-glucoside, malvidin-3-galactoside and malvidin-3-glucoside were achieved by analysis of standard. The results showed that accuracy and feasibility of the correlation coefficients was 0.9939~0.9968, precision RSDs of 2.00%~3.73% (n=5) and the recovery rates of six anthocyanins were in the range of 98.90%~100.99%. Delphinidin-3-galactoside, cyaniding-3-galactoside, malvidin-3-galactoside were contained in all samples by the intercomparison of 6 standards in 15 samples. The average content of delphinidin-3-galactoside and malvidin-3-galactoside were 223.99 and 153.34 μg/g with 65% of the total anthocyanins. Cluster 1 showed the higher contents of delphinidin-3-galactoside was contained by Lijiang Legacy, Lijiang O'neal, Jingyu Duke and cluster 2 showed the higher content of total anthocyanins of Lijiang Northland, Jingyu Earliblue by the cluster analysis of euclidean distance. In addition, the contents of delphinidin-3-galactoside and total anthocyanins were the evaluated important factor of blueberries anthocyanins characteristics.
