Chemical Composition of Green Pea (Pisum sativum L.) Pods Extracts and Their Potential Exploitation as Ingredients in Nutraceutical Formulations

Agro-industrial wastes contain a large number of important active compounds which can justify their use as innovative ingredients in nutraceutical products. This study aimed to provide a complete analysis of active molecules, namely (poly)phenols in pea pods water-based extracts, through a UHPLC-Q-Orbitrap HRMS methodology. Data showed that 5-caffeoylquinic acid, epicatechin, and hesperidin were the most relevant (poly)phenols found in the assayed extracts, with a mean value of 59.87, 29.46, and 19.94 mg/100 g, respectively. Furthermore, changes in antioxidant capacity and bioaccessibility of total phenolic compounds (TPC) after the simulated gastrointestinal (GI) process were performed using spectrophotometric assays (FRAP, DPPH, ABTS, and TPC by Folin-Ciocalteu). The acid-resistant capsules (ARC) and the non-acid resistant capsules (NARC) containing the pea pod extract underwent simulated GI digestion. The results suggested that the ARC formulations were able to preserve the active compounds along the simulated GI process, highlighting a higher TPC value and antioxidant capacity than the NARC formulations and the not-encapsulated extracts. Hence, the pea pods water-based extracts could be utilized as a potential alternative source of active compounds, and the use of ARC could represent a suitable nutraceutical formulation to vehiculate the active compounds, protecting the chemical and bioactive properties of (poly)phenols.

Different Agricultural Wastes as Substrates for Growth and Production of Pleurotus florida

The present study was done impact of agricultural wastes on growth and production by oyster mushrooms i.e., Pleurotus florida which have a rich source of protein and also has important medicinal properties. The yield and Biological efficiency of different lignocellulosic agricultural wastes viz. Wheat straw, Maize leaves, Cob leaves, Jawar residue, Bajra residue, Bamboo leaves, Paddy straw, Sugarcane, Cotton, Soyabean, Safflower (Pods residue), Pigeon pea (Pods residue), Mung bean (Pods residue), Cowpea (Pods residue). the paddy straw showed the highest yield 892.25 gm with the highest biological efficiency 89.09 % followed by Cowpea pods residue gives 879.65 gm yield of Pleurotus florida and shows biological efficiency of 87.72%, followed by Wheat straw substrate showed 871.18 gm yields with 87.27 % biological efficiency. The Pigeon pea pod residue showed 865.85 gm yield during three harvestings having 86.36% biological efficiency. Similar result was seen Bajra residue and soybean pod residue in bajra residue showed 792.45gm yield during three harvestings having 79.245% biological efficiency, in soybean pod residue showed 791.63 gm yield during three harvestings having 79.163 % biological efficiency. The lowest yield was seen in Bamboo leaves and cotton residues. In cotton residue substrate 433.22 gm total yield along with 43.32% biological efficiency, Bamboo leaves substrate total yield were seen 438.12gm with 43.81 % biological efficacy.

FEATURES OF THE NUTRITIVE STATUS OF PREMATURE INFANTS WITH BRONCHOPULMONARY DYSPLASIA IN THE FIRST HALF-YEAR OF LIFE

Objective of the study: assessment of the nutritional status of infants with bronchopulmonary dysplasia. Materials and methods of research: a retrospective uncontrolled non-randomized cross-sectional comparative study was carried out. It involved 40 premature babies (boys – 19, girls – 21) at the corrected age of 3,3 [2,3–4,0] months and 16 age matched full-term babies (comparison group). Children born prematurely were divided into 2 groups depending on their body mass (BM) at birth: 1st – 25 children with BM less than 1500 g, 2nd – 15 children with BM from 1500 to 2500 g. The first group included subgroups 1A and 1B, depending on the presence or absence of bronchopulmonary dysplasia in children. Physical development was assessed using INTERGROWTH-21st and WHO Anthro, 2009 anthropometric calculators, body composition was determined by air plethysmography using a PEA POD apparatus. Results: the assessment of anthropometric indices (WAZ and HAZ) calculated for postnatal and corrected age revealed the most severe manifestations of nutritional deficiency in children with very low BM at birth who developed bronchopulmonary dysplasia. The percentage of fatty BM was statistically significantly lower in children of subgroups 1A and 1B compared to full-term infants (p<0,006), as well as fatfree BM (p<0,012). Conclusion: the slow development of anthropometric indicators of premature babies with very low BM, especially those with bronchopulmonary dysplasia, indicates the need for timely correction of their nutrition.

A study of life cycle of vegetable pests in Ranchi

The study is done to investigate the different pests found in the vegetables in Ranchi. The pests who damage these vegetables are Plutella xylostella (cauliflower pest), Earias vittella (Okra Pest), Etiella zinckenella (pea pod borer) and Thysanoplusia orichalcea (coriander leaf pest). The pests’ life cycle was studied in detail by culturing the insect in the laboratory. Pest problem is one of the major constarints for getting good yield in the agricultural crops. India also suffers a huge loss in crop yield due to pests and diseases each year. The study of life cycle of the pests show that the insects undergo metamorphosis and the larval stage is the damaging phase of the life cycle. The use of pesticides to kill the pests causes environmental pollution which has become an increasing problem.
