Evaluation of Nutrient and Anti-nutrient Contents of Parkia biglobosa (L.) Flower

Abstract

Nutritional and antinutritional contents of Parkia biglobosa flower were analysed using standard analytical methods. On dry weight basis, the flower had the following proximate compositions; ash (6.50 ± 1.00%), crude lipid (4.66 ± 0.29%), crude protein (6.77 ± 0.15%), available carbohydrate (78.9 ± 1.18%) and crude fibre (3.17 ± 0.29%). The calorific value was 384.7 kcal/100g. Mineral analysis indicates that the flower contain some essential minerals such as K, Na, Ca, Mg, and Zn, but was low in Cu, Mn, and Fe. The flower has low concentration of anti-nutritive factors: phytate (1.41±0.24mg %); oxalate (0.03±0.01mg %); hydrocyanic acid (0.17±0.01mg %) and nitrate (1.32±0.10mg %). The values
are below the reference toxic standard levels. Therefore, P. biglobosa flower could supplement the microelements requirement, energy and to some extent protein.
