This study evaluates the nutritional and anti-nutritional potentials of the aerial part of Lablab purpureus as it relates to its use in Animal nutrition. The preliminary phytochemical test of the plant revealed the presence of bioactive secondary metabolites; glycosides, saponins, flavonoids, tannins, steroids, alkaloids, coumarins, phenols, carbohydrates and terpenoids in the crude extract. Results from the study revealed significant mineral composition in Lablab purpureus. Atomic Absorption Spectroscopic (AAS) technique was employed in the elemental analysis. Substantial amounts of Ca, Na, K and Mg were found, while Cu, Fe, P, Mn and Zn were present in trace amounts. Proximate analysis revealed the ash and fat contents to be 5.6 % and 4.2 % respectively. The protein level, total Carbohydrate and Fibre contents were determined to be 25.4 %, 46.93 % and 7.5 % respectively. The presence of anti-nutritional secondary metabolites; tannins, saponins, oxalates, phytates, cyanogenic glycosides and free phenolics were quantitatively determined to be 0.50 %, 3.8 %, 0.70 %, 2.2 %, 1.2 % and 2.1 % respectively. The results of the phytochemical constituents, proximate composition, anti-nutritional factors and mineral composition of the aerial part of Lablab purpureus in this study demonstrates high nutrients content with potentials to meet the nutritional requirements in monogastric diets.Keywords: Anti-nutritional composition, Lablab Purpureus, Mineral composition, Proximate analysis

Background: Sorghum (Sorghum bicolor) is commonly named as Jowar, belongs to family Framineae. The presence of anti-nutrients affect the nutritional values by limiting protein and starch digestibility, hinder mineral bioavailability. This can be reduced by malting procedures. Hence, the study was undertaken to study the effect of malting on nutritional composition, anti nutritional factors and mineral composition. Methods: Processing methods include soaking for 24 hr and germination for different time periods and drying in hot air oven for 2-3 hr. at 50oC. The yield of malted sorghum flour is 95g/100g. Result: Nutrient composition include moisture, protein, fat, ash, crude fibre, carbohydrate and energy showed that the sorghum germinated for 3 days has the higher value of 6.7%, 11.37g, 3.27g, 1g 2.4g 73.57g 375 /100g respectively. The micronutrients i.e. calcium and iron content of malted flour was significantly increased (p less than 0.05) to 28mg/100g, 5.83mg/100g. Anti-nutrients like Tannin and Phytate decreased subsequently in three day germinated sorghum to 61.2mg/100g, 50.625mg/100g respectively. The result showed that processing increases the nutritional, mineral composition and decreases theanti-nutritional factors in sorghum. Hence, Sorghum has potential in fortification of food productsand its suitability of utilization in formulation of value added food products.

<em>Adenocalymma peregrinum</em>, popularly known as <em>ciganinha</em>, is an aggressive pasture invader. This species has a vegetative propagation mechanism that includes aerial latent buds and subterranean stalks activated by cuts and other lesions. In the present study, we evaluated the levels of cytokinins and secondary metabolites in <em>A. peregrinum</em> during regeneration of the aerial part. Plants used in this experiment were established in the field and were cut at intervals of five days until the 25th day. The regeneration of the cut plants started on the 10th day after the first cut. Among observed compounds, only kinetin, allantoin and the iridoide 6-β-hydroxyipolamiide were detected at adequate levels for comparative evaluation. The maximum levels of these compounds coincided with the beginning of regeneration in these plants, indicating the involvement of these compounds in the regeneration process.

Emulsified Meat

Frankfurters are the most widespread type of emulsified meat product in the world. However, they could be considered unhealthy due to their high-fat content (15–30%). The meat industry wishes to change the perception of these products by reformulating them. One strategy is increasing the content of compounds considered beneficial for human health. Thus, the aim of this study was to determine the chemical, physico-chemical, and sensorial properties of Frankfurter-type sausages added with roselle (Hibiscus sabdariffa L.), extracts. Frankfurter-type sausages were made following a traditional formula. Three different formulations were prepared. The original mixture was used as a control sample (CS). The other samples were formulated by adding roselle extract at 4.08% (FRE4) and 8.17% (FRE8). For proximate analysis, no statistical differences were found between FRE4 and FRE8 and CS. However, the residual nitrite levels decreased from 88.41 mg NaNO2/kg in CS to 86.31 and 69.82 mg NaNO2/kg in FRE4 and FRE8, respectively. Regarding the sensory analysis of the frankfurters, CS and FRE4 samples generally scored significantly higher than FRE8 for all the parameters considered. This study suggests that the reformulation of Frankfurter-type sausages using roselle extracts is feasible and represents a viable alternative to improve the safety and the nutritional composition of the product.

Objective: Aglaia malabarica is an unexplored endemic forest tree belonging to the family Meliaceae. The present study was conducted to screen the phytochemical constituents of the leaf extract, to analyze the important secondary metabolites and to determine the antibacterial efficacy of the plant extract.Methods: Antibacterial activity was studied using agar based disc diffusion method. Four strains of bacteria were used for the antibacterial study that includes Staphylococcus aureus, Pseudomonas aeruginosae, Proteus vulgaris and Bacillus megaterium.Results: The presence of constituents like, carbohydrates, proteins, tannins, phenols, terpenoids, flavonoids, alkaloids and steroids were confirmed. Saponin was found to be absent. The secondary metabolites quantified were terpenoids, phenols and flavanoids, which were found in considerable amounts. The minimum inhibitory concentration (MIC) of all the bacteria studied was found to be 500 µg methanolic leaf extract.Conclusion: The plant extract was found to be highly potent against both the Gram positive and Gram negative strains and this property may be attributed to the potent phytochemicals revealed in the extract.
