Abstract

Agricultural residues are excellent alternative materials to lignocellulosic materials because they are inexpensive, easily processed, plentiful, and renewable. Optimization and the influence of additive on the interfacial bonding between Cocoa fruit shell powder and Polypropylene-based composite was carried out. The methods use include, water absorption, tensile strength, impact strength, hardness, and SEM. From the studies it was shown that the water absorption property of the composites decreases with increase in CaCO3 content in the matrix for all the composites investigated. The tensile strength of the modified composite increases with additive. The impact strength results are 4.17 kJ/m3 to 5.58 kJ/m3 for unused/treated composites, 3.47 kJ/m3 to 5.27 kJ/m3 for waste/treated composites. It was observed that the hardness for the modified composite ranges from 39 MPa to 63 MPa for unused polypropylene/treated and, 33.43 MPa to 52.77 MPa for waste polypropylene/treated composites. Based on SEM images, it can be said that the use of Alkaline treated Cocoa fruit shell powder and microcrystalline cellulose resulted in better-dispersed structures in the polymer matrix. This project mitigates environmental impact without compromising structural integrity by exploring Theobroma cacao and Polyethylene modified composite materials.

Abstract

Spathodea campanulata is a medicinal plant useful in traditional medicine for the treatment and prevention of some diseases of bacterial and none microbial origins. As a result of this, it becomes very important to investigate the phytochemical and antimicrobial activities of the flower extract. 200 g of S. campanulata air dried flower ground to powder was extracted with methanol. The flower extracts showed qualitatively the presence of saponin, steroid, flavonoids, alkaloids, phenol, tannin, and terpenoids while glycosides were absent. S. camapanulata exhibits selective antimicrobial properties, being particularly effective against Staphylococcus and somewhat against Pseudomonas, but showing no significant activity against Candida or Aspergillus.

Abstract

Ixora coccinea, also known as jungle geranium, is a flowering plant from the Rubiaceae family. It is a tiny, bushy shrub that produces beautiful scarlet flowers and is commonly grown for its ornamental qualities. In addition to its visual appeal, Ixora coccinea has long been employed in a variety of therapeutic traditions due to its potential health advantages. The aim of this work was to conduct phytochemical screening and antimicrobial analysis on a methanolic extract of the flower of Ixora Coccinea. Phytochemicals are plant-derived bioactive molecules that have been proved to offer a variety of health benefits. The phytochemical screening of the methanolic extract identified alkaloids, glycosides, proteins, tannins, saponins, phenols, terpenoids, and steroids while flavonoids was absent. The antimicrobial results of the investigation demonstrated that Ixora coccinea floral extract had strong antibacterial activity against a variety of pathogens. Minimum inhibitory concentration (MIC) values for the extract ranged from 25 % to 75 % while the minimum bactericidal concentration (MBC) values for active extract ranged from 15 to 37 mg/ml. The extract had inhibitory effects on both Gram-positive and Gram-negative bacteria, as well as fungal strains. These findings indicate that the phytochemicals found in Ixora coccinea have powerful antibacterial activities that could be used for medicinal purposes.
