Millets are group of underutilized cereal crops with higher nutritional values. The present investigation used different classes of minor millets, including barnyard (sava), little (kutki), finger (ragi), kodo and foxtail millets, for evaluation of their nutritional parameters, i.e., the content of proteins, total amino acids, total sugars, insoluble fibers, soluble fibers, total dietary fibers, iron (Fe) and zinc (Zn), along with antinutritional and antioxidant parameters, viz., tannic acid, phytic acid, phenol, flavonoid, proline and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. Alpha amylase and alpha glucosidase activity were also thought to elevate millets as a viable staple meal. Foxtail millet showed the maximum inhibition, with an IC₅₀ value of 20.46 ± 1.80 µg mL⁻¹ with respect to α-amylase. The coefficient of correlation between nutritional and antinutritional compositions showed that the starch content was significantly and positively correlated with insoluble fiber (r = 0.465) and dietary fiber (r = 0.487). Moreover, sugar was positively correlated with the phytic acid (r = 0.707), Fe and Zn (r = 0.681) contents. To determine the peptides responsible for anticancer activity, the foxtail protein was subjected to ultrafiltration; it was found that the 3 kDa fraction retained the greatest anticancer activity. Selected millet germplasm line(s) that have the best nutraceutical properties could be used in millet improvement programs.

Chickpea is an important food legume of the world offering valuable nutrients. Employing the degree of hydrolysis (DH) by the enzyme alcalase and

Chickpea seeds are the source of proteins in human nutrition and attribute some nutraceutical properties. Herein, we report the effects of chickpea seed bioactive peptide on albumin, insulin, lactoglobulin and lysozyme amyloid fibril formation. Employing thioflavin T (ThT) assays and circular dichroism (CD), amyloid structural binding transition was experimented to analyze the inhibition of amyloid fibril formation. The purified active peptide with a molecular mass of 934.53 Da was evaluated in vitro for its ACE-I inhibitory, antibacterial, antifungal and antidiabetic activities. Further, in vivo animal studies were carried out in wistar rats for blood pressure lowering action. In hypertensive rats, chickpea peptide decreased 131 ± 3.57 mm of Hg for systolic blood pressure and 86 ± 1.5 mm of Hg for diastolic blood pressure after 8 h intraperitoneal administration. Additionally, the peptide suppressed the fibrillation of amyloid and destabilized the preformed mature fibrils. Data emphasize efficacy of chickpea peptide vis-a-vis ACE-Inhibitory, antibacterial, antifungal, antidiabetic and anti-amyloidogenic activities, allowing us to propose this novel peptide as a suitable candidate for nutraceutical-based drugs and seems the first kind of its nature.

Background: Groundnut (Arachis hypogaea L.) is an exceedingly nutritious legume being employed for farming globally. The characterization of groundnut for genetic diversity and population structure can be used for unswerving detection of phenotype x genotype relations. Methods: The investigation was carried out with groundnut germplasm lines for nutritional and anti-nutritional profiling i.e., total sugars, proline, total amino acid, DPPH, phenol, phytic acid, flavonoid, lipid peroxidation and superoxide dismutase activity (SOD) along with molecular characterization and population structure analysis for early and late leaf spot diseases. Result: The heat map ranged between (-4 to 4) and represents the level of expression of diverse biochemical parameters. The genetic diversity for markers S008 and S053 ranged between 0.2293 to 0.5269 and PIC values ranged between 0.203 to 0.4224 for S008 and S053 molecular markers, respectively. The number of sub populations (K) was constructed based on maximum likelihood and delta K (dK) values subdivided into three subgroups. Employing a membership probability threshold, 31 genotypes were allocated to subgroup (SG) 1, 15 genotypes to SG 2 and rest of the genotypes was mixed proportions.

Background: Drought is the foremost environmental restraint that effects the growth and yield of chickpea. The mechanism of response to drought differs with genotype and growth stages of individual crop species. The activation of antioxidant enzymes is an alternate defensive system against oxidative stress that ultimately decide development of putative drought tolerant mechanism. Methods: Eighty-three chickpea genotypes were grown under normal and drought stress conditions and leaf samples were used to estimate different biochemical parameters including total sugar, lipid peroxidation (MDA), chlorophyll, proline and protein along with estimation of activities of different antioxidant enzymes viz., catalase (CAT) (EC 1.11.1.6), ascorbate peroxidase (APX) (EC 1.11.1.11), superoxide dismutase (SOD) and peroxidase (POX). Result: Positively significant correlation was found among proline under control with proline underwent stress (r=0.441), MDA under stress with proline under control (r=0.365) and MDA under control (r=0.336) at 1% level of significance. Positively significant correlation was also investigated between SOD under stressed condition with SOD under control (r=0.665), POX (0.449) and APX under stress (0.423), CAT under control (0.471) and CAT under stress condition (0.374) at 1% probability level. Heatmaps along with dendrograms represented expression levels of different antioxidant enzymes activities that showed variations among different genotypes. In conclusion. total sugar, proline and Malondialdehyde, have been increased under drought stressed condition whilst total chlorophyll and protein were decreased. While antioxidant enzymes viz., POX, APX, CAT and SOD levels increased under drought stressed conditions.
