Analysis of Anthocyanin Content in Different Variety Resources of Colored Rice

In order to screen the germplasm resources of rice with high content of anthocyanins, 124 varieties of colored rice were used as research materials, and the content of anthocyanins in different varieties of colored rice was determined by pH-differential method. The results showed that there were very significant differences in the content of anthocyanins in different varieties of colored rice. The three materials with the highest content were all the varieties of black rice, among which the black rice HY023 had the highest content, reaching 22.01 mg·hg^-1, while the red rice HY102 had the lowest content, reaching 8.06 mg·hg^-1. The mean content value of anthocyanins in 124 varieties of colored rice was 12.90 mg·hg^-1, and two varieties had higher content of anthocyanins (>19 mg·hg^-1).
