Nicotinic Acid, Pantothenic Acid and Biotin in Fruits, Vegetables and Nuts

Nicotinic acid, pantothenic acid and biotin in fruits, vegetables and nuts.

Little information is available about the vitamins of the B group (with the possible exceptions of aneurin and riboflavin) in fruits and vegetables, particularly those most widely cultivated in the British Isles. The riboflavin contents of home-grown fruits have been surveyed by the author (James, 1944). This paper records estimations, made in the 1947 and 1948 seasons, of nicotinic acid, panto...

The daily excretion of riboflavin biotin, pantothenic acid, and nicotinic acid derivatives by normals.

Flavonoid content of U.S. fruits, vegetables, and nuts.

Analytical data are reported for 20 flavonoids (as aglycones) determined for more than 60 fresh fruits, vegetables, and nuts collected from four regions across the United States at two times of the year. Sample collection was designed and implemented by the Nutrient Data Laboratory (USDA). Analyses of eight flavan-3-ols (catechin, catechin gallate, epicatechin, epicatechin gallate, epigallocate...

Determination of Ascorbic Acid Contents of Fruits and Vegetables

Ascorbic acid contents of some fruits and vegetables in Abakaliki were analyzed through titrimetric methods. The results recorded the concentrations (mg/100g) of ascorbic acids in various fruits as orange (15.47 ± 0.23), lemon (12.87 ± 0.45), grape (2.00 ± 0.10), paw-paw (46.40 ± 1.65), apple (2.20 ± 0.10), banana (1.87 ± 0.06), carrot (1.80 ± 0.04), pineapple (2.80 ± 0.10), water melon (2.27 ±...

Pantothenic Acid and Acetic Acid Utilization in Tomato Fruit-set.

Fruit-set in the tomato has been shown to be dependent upon the presence of mature leaves (3). The nature of the nutritive materials supplied by the leaves has been studied by use of excised tomato flowers cultured on an agar medium to which various nutrients have been added. Of the organic acids tested, all those participating in the Krebs tricarboxylic acid cycle were found to be effective in...
