Abstract;In this experiment, 12 kinds(2 kinds of them were 2 varieties) of marketable vegetables were roughly divided into the colored and lightly colored ones; analysis of contents of chlorophyll, carotenoid, vitamin E, vitamin C, and minerals was carried out and then the following result was obtained.With regard to chlorophyll, a considerable content of pheophytin was found in all of them except for carrots, indicating that a considerable amount of chlorophyll became decomposed toward the harvest from the growth period.It was difficult to measure the degree of decomposition of chlorophyll, and there was no clear standard for the measured values; it became clear that there was a difficulty in classification of the colored and lightly colored ones.The above result showed that the retinol equivalent converted from the .BETA.-carotene equivalent could provide a basis for distinguishing between the colored and lightly colored ones.Moreover, lycopene can be detected from tomatoes and carrots, showing red color, but cannot become the retinol equivalent.And though capsorubin and capsanthin which have been detected from pimientoes are also orange-red-colored, it cannot become the retinol equivalent.Vitamin E is rich in colored green vegetables such as beefsteak plant, garland chrysanthemum, leek, parsley and spinach.It was proven that there was a small amount in tomatoes and pimientoes(fruit vegetables).It was estimated that vitamin C accumulated from the period of green unripe fruits to become the considerable content. That is to say, it became clear that vitamin C with the endiol group increased together with the decrease of chlorophyll.Of the minerals, K and Ca are extraordinarily abounding as compared with others; on an average K occupied 80% and Ca occupied 18%, with their being relatively abounding in colored ones.Next to them, Mg was abundant, and generally mineral contents were more abundant in the colored(greenish yellow) vegetables than in the lightly colored ones.
