Aframomum alboviolaceum is a plant that belongs to the family of Zingiberaceae, genus Aframomum and species of A. alboviolaceum. It is wide spread across tropical Africa and represented about 50 species. Proximate analysis is usually done to determine the values of macronutrients present in plant or food sample; it gives the composition of the biomass in terms of gross components. Proximate analysis includes determination of: Ash (sodium, potassium, iron, calcium, phosphorus) and other dietary minerals; moisture, proteins, fats, carbohydrate (dietary fibre, sugars, sugar alcohol, e.t.c). A. alboviolaceum (ridl.) k. schum) harvested in Republic of the Congo proximate analysis revealed the presence of  lipids (10.58%); humidity (30.68%); protein (5.19%); carbohydrate (52.37% with 3.86% of dietary fibre); ash (1.18%) (Phosphorus=0.14%, Calcium=0.72%, Magnesium=0.29%, Iron=0.00%). The calculated energy value is 325.46 Kcal / 100 g.


Key words: Aframomum alboviolaceum (Ridl.) K. Schum., fruit, seeds, physico-chemical.
