Abstract:
The search for solution to malnutrition problem in it various forms particularly in developing countries necessitated the exploration of indigenous plants and spices that has been widely utilized for diverse purposes. The study was aimed at evaluating the nutrients composition of costus lucanusianus stem which include proximate, minerals, vitamins and amino acids analyses. Proximate composition was assessed by AOAC methods, minerals by (AAS), and vitamins by U.V spectrophotometer and amino acid by Gas chromatography spectrophotometer. Proximate composition revealed moisture content (74.87±0.70mg/100g), carbohydrate (19.44±0.98mg/100g), crude fiber (3.24±1.29mg/100g), crude fat (1.10±0.26mg/100g) and ash (0.89±0.19mg/100g) the least. Caloric value (kcal/100g) was 89.54±6.46. Macro and micro minerals includes calcium (28.14±27.11mg/100g),Phosphorous (20.50±17.17mg/100g) and Potassium (18.34±17.12mg/100g) Iron (35.56±17.12) and Zinc (21.91±0.63). Vitamin present include vitamins B2 (1.85±0.65), B6 (1.75 ± 0.01), B9 (1.75 ± 0.01mg/100g), B1 (1.36 ± 0.10mg/100g), A (1.04±0.00mg/100g), and E (1.20. ±0.07mg/100g). Amino acid present include lysine (20.38 ± 0.15mg/100g), threonine (18.58 ± 0.24mg/100g), methionine (16.21 ±0.57mg/100g) and Phenylalanine (13.47 ±0.41mg/100g). Glutamine (41.41±0.93mg/100g), cystein (37.90 ±0.39mg/100g), asparagine (27.25±0.10mg/100g), alanine (23.33±0.40mg/100g), aspartic acid (21.36±0.41mg/100g) and glutamic acid as the least (0.07±0.02mg/100g). Costus lucanusianus stem, could serve as herbal nutritional supplement considering its rich macro and micro nutrients constituent.
