The amount of dietary fiber (neutral detergent fiber, acid detergent fiber and lignin) in the edible portion; leaf, stalk and bud; of 53 species of wild plants was determined by Van Soest method and also the amounts of crude fiber, water, fat and ash of these plants were estimated. These plants were taken in Fukushima prefecture and belonged to Compositae, Liliaceae, Umbelliferae, Polypodiaceae, Araliaceae, Cruciferaeae, Uruticaceae, Polygonaceae, Caprifoliaceae, Equisetaceae, Rosaceae, Lardinabalaceae, Campanulaceae, Leguminosae, Chenopodiaceae, Saururaceae, Plantaginaceae, Berberidaceae, Saxifragaceae, Rutaceae, Gramineae, Actinidiaceae and Clethraceae. Takadiastase digestion of plant before analysis of neutral detergent fiber had little effect on the amount of neutral detergent fiber in leaf, stalk and bud of wild plants. The amounts of neutral detergent fiber, acid detergent fiber and crude fiber of these plants were 1.07 to 5.92%, 0.79 to 5.19% and 0.64 to 3.67% respectively. The correlation (r) of c ude fiber with neutral detergent fiber, acid detergent fiber and cellulose; the difference between acid detergent fiber and lignin; were 0.63, 0.65 and 0.77 respectively. Neutral detergent fiber had a little correlation with nitrogen free extract (r=-0.64) but no correlation with protein and ash (r=-0.24, 0.22).
