title: The biochemical composition and nutritional potential of the tribal pulse, Mucuna monosperma DC. ex Wight.
abstract: Two germplasms of the tribal pulse, Mucuna monosperma Dc. ex Wight, viz., Thirunelly Reserve Forest, Wynaad District (Kerala) and Siruvani Reserve Forest, Coimbatore District (Tamilnadu), were analysed for proximate composition, total (true) seed proteins, seed protein fractionation, amino acid composition, fatty acids, minerals and anti-nutritional factors. Crude proteins, crude lipids, ash and nitrogen free extractives constituted 23.10%, 4.36%, 3.80%, 61.74%, respectively, in Tamilnadu germplasm; whereas, in Kerala germplasm they constituted 20.13%, 8.99%, 3.60% and 61.69%, respectively. The calorific values of 100 g dry matter of seed material are 408.19 KCal (Kerala) and 378.60 KCal (Tamilnadu) germplasms. Essential amino acids like methionine, cystine, threonine and valine were found to be limiting in the seed proteins of both the germplasms. The fatty acids like lauric acid and palmitic acid are found to be common in both the germplasm seed samples, while linoleic and oleic acids in Kerala germplasm and stearic acid in Tamilnadu germplasm are present. The Tamilnadu germplasm seems to be a rich source of sodium, magnesium, zinc, manganese, copper and iron; whereas the Kerala germplasm seems to be a rich source of phosphorus. Antinutritional substances like total free phenols, tannins, L-DOPA, trypsin inhibitor activity and phytohaemagglutinating activity also were investigated.
