The chemical composition of Sterculia setigera

Abstract

Samples of Sterculia setigera seeds were analysed for proximate composition, elemental and amino acid composition. The nutritive value of the seed was extrapolated by comparing its oil, protein crude fibre, ash and nitrogen free extract (NFE) contents with other known edible seeds. Comparison of the results with the recommended nutrient requirements showed that the seed is adequate in its protein content. Quantitative chromatographic analysis of the seed hydrolysates revealed 18 amino acids. Comparing the amino acids of kukkuki with hens egg, showed a higher superiority in alanine, arginine, aspartic, cystine and histidine but a deficiency in isoleucine and leucine.
