Succeed to structural elucidation, the anthocyanins in the Korean restive Brassica juncea were quantitatively investigated. And obtained results were as follows: 1. The amount of total anthocyanins showed a little difference according to harvesting season, such as 175.5㎎% in spring and 192.7㎎% in autumn, as peonidin-3-glucoside. 2. By colored degree of leaf, the amount of total anthocyanins showed 290.2㎎% in both side colored, 73.6㎎% in one side colored and 40.0㎎% in none colored as peonidin-3-glucoside. 3. The characteristic color of fresh Brassica juncea couldn`t he detected with naked eyes within the limits of 40㎎% of anthocyanin as peonidin-3-glucoside. 4. There were no differences with the harvesting season and the colored degree in the ratio of two kinds of anthocyanins, which was consisted of 57.3% of peonidin-3-glucoside and 44.7% of peonidin-3-galactoside.
