Dehulled and defatted flour of urdbean (Vigna mungo), Var T-9, contained 25% protein with maximum contribution by globulins (63%). Albumins and glutelins contributed 12% and 21% respectively, whereas prolamins were present only in traces (1%). Globulins were further fractionated into legumin and vicilin type proteins which were present in the ratio of 4:1. All the protein fractions were heterogenous in nature as revealed by high performance liquid chromatography. SDS-polyacrylamide gel electrophoresis revealed the total protein sample to contain 21 different components with molecular weights ranging from 8.92 to 117.49 kd. Albumins, globulins, prolamins and glutelins resolved into 4, 8, 6 and 13 different sized components of molecular weights ranging from 10.23 to 25.53, 10.84 to 112.72, 10.33 to 51.52 and 8.91 to 112.72 kd, respectively. Amino acid analysis of all fractions revealed that glutamic acid was present in maximum concentration followed by aspartic acid and lysine. Just like other pulse proteins, the urdbean proteins were also deficient in sulphur containing amino acids.

Seeds of 28 wild growing legumes of India were analysed for their protein content and amino acid compositions. A wide variation was observed in protein contents (18.3 to 50.9%). The amino acid composition and protein content of some of these seeds were in close proximity to that of soybean; however, some legumes registered a higher level of certain amino acids and protein as compared to the latter.

Barley grains (9 samples from 7 cultivars) with nitrogen contents (N) ranging from 1.45 to 4.01% of dry matter were analysed for their amino acid (AA) composition with high accuracy from six different hydrolysates per sample. AA levels in grain increased as linear functions of N with correlation coefficients close to unity. A comparison with literature data confirmed that the AA composition of any grain sample of normal barley can be predicted from its N for all phenotypes and genotypes. AAs in grain protein changed as hyperbolic functions of N which increased for Phe, Pro and Glx but more or less strongly decreased for the other AAs. By plotting AA scores against N, barley proteins were shown to be always richer than wheat and rye in Val and Phe + Tyr; sometimes richer than both other species for N less than 2 (Lys); 2.2 (Leu and Ile); 3.4 (Thr); sometimes intermediate to wheat and rye above the latter N values. They were also intermediate in sulphur AAs for N less than 1.9 and drastically poorer for N greater than 1.9. However, they were richer than both other species in Trp for N greater than 1.6. The hyperbolic variations of non-protein nitrogen and nitrogen-to-protein conversion factors were determined as a function of N and also compared with those of wheat and rye.

White and brown ragi (Eleusine coracana) varieties were analysed for tannin, phytate phosphorus, total phosphorus, iron, ionisable iron, zinc and soluble zinc content. White ragi had no detectable tannin while in brown varieties it ranged from 351 to 2392 mg per 100 g. Germination brought about a progressive decrease in tannin and phytate phosphorus and an increase in ionisable iron and soluble zinc content of grain ragi. Both in raw and germinated grain, ionizable iron was significantly higher in white than in brown varieties. While ionisable iron was inversely correlated with the level of tannin and phytate phosphorus, soluble zinc was negatively correlated with phytate phosphorus. After extraction of tannin, ionisable iron of brown ragi rose by 85%. On the other hand, in white varieties, addition of tannin extracted from brown ragi, resulted in a 52-65% decrease in ionisable iron content. These studies indicated that poor iron availability in ragi as judged by its low ionisable iron content was due to the presence of tannin in the grain.

A tobacco leaf protein concentrate (TLPC) from bidi tobacco leaves was prepared by a heat coagulation method which contained 52% protein and was free from nicotine and polyphenols. When TLPC was fed to weanling wistar albino rats to supplement 25% of the dietary protein, the growth of the animals was found to be comparable to control animals. Reproductive performance of male and female rats fed the TLPC supplemented diet was normal and no histopathological changes were seen in their tissues.
