To furnish basic data for the utilization of leaf mustard as a raw material of salted and fermented vegetable food, the contents of carotenoids and chlorophylls of Dolsan Leaf Mustard(DLM) were investigated. Total carotenoid content of DLM was 4.75 mg%, and the compositions were ${eta}-carotene(80.91%)$, lutein(13.07%), lutein epoxide(3.93%). The contents of chlorophyll a and b were 4.1 and 1.5 mg%, and leaf was 7.4- and 8.1-fold, respectively, higher than leaf stalk. The ratios of chlorophyll a/b in leaf (2.7:1) and leaf stalk(3.0:1) were similar to those of other vegetables.
