The article assesses the cytotoxic effects on cervical cancer cells and conducts molecular docking analysis to understand the biological activities and binding interactions of lycopene. The formulations are analysed for their phytochemical profile, and their in vitro antioxidant activities are evaluated using spectrophotometric methods. Cytotoxicity tests on cervical cancer cells demonstrate that the ethanol extract of tomatoes exhibits the highest cytotoxic inhibition (40.28%), while carrots show minimal cytotoxic effects. Moreover, the lycopene extract exhibits dose-dependent cytotoxicity, with the highest concentration (1,000 µg/mL) displaying remarkable inhibition (74.2%). Molecular docking analysis indicates favourable interactions between lycopene and the pro-apoptotic protein BAX 1, suggesting its potential to induce apoptosis in cervical cancer cells, but camptothecin demonstrated stronger interactions. Molecular dynamics simulations confirm the stability of lycopene-protein complexes throughout the 100 ns simulation, supporting their potential as anticancer agents. Overall, the study highlights the cytotoxic effects of tomato-carrot food extracts and lycopene on cervical cancer cells. Molecular docking reveals the potential of lycopene to induce apoptosis through interactions with BAX 1. The stability analysis of lycopene-protein complexes further supports its anticancer properties. These findings enhance our understanding of the molecular mechanisms underlying the anticancer effects of lycopene and provide insights for future research on novel chemopreventive strategies for cervical cancer. However, further in vivo and clinical studies are warranted to validate the efficacy and safety of lycopene-based interventions.

This is due to the high cost, non-availability, and side e ects associated with the unregulated consumption of pharmaceuticals. Over the ages, nutraceuticals from food products were reported to contain bioactive compounds with great health and physiological benefits. This report reviews bioactive compounds in selected foods namely ginger (Zingiber o cinale), turmeric (Curcuma longa), and garlic (Allium sativum) as potential natural therapeutics for ailments of cancer and heart-related diseases. Analytical profiles, functional activities, and characterization of these compounds were discussed with possible recommendations for the prospective treatment of diseases using these nutraceuticals.

The cancer incidence in the low and middle-income countries has risen due to several factors, but notably, it has been due to poverty and the non-availability of screening centers. The non-toxic nature, high availability, and low cost of food-based nutraceuticals have been a significant advantage to its users. Solanum lycopersicum is well-known to possess excellent antioxidant, anti-inflammatory, and anticancer potential, and this has been attributed to its potent bioactive compound, lycopene. The presence of β-carotene in Daucus Carota has also contributed immensely to its antioxidant and anticancer properties. Nutraceuticals are considered suitable for anticancer drug development due to their pleiotropic actions on target sites with multiple effects. This short review h...

Most of synthetic inhibitors is expensive and not environmental friendly, hence, the need for cheap, renewable, non-hazardous and green inhibitors to handle environmental issues. In this particular study, the inhibitory properties of Epimedium grandiflorum plant extract on the corrosion of mild steel in HCl acidic media was investigated. The gasometric, weight loss and the linear polarization methods were used in the study with adsorption isotherms (Langmuir, Freundlich, Frumkin and Temkin) validating the state of the reaction. The concentration of the extract was prepared in serial dilution of 10-50% using a stock solution of 1.75 M HCl. Mild steel coupons of known elemental compositions were immersed in test solutions of both stock solution and extract solutions. In the gasometric method, a decrease in volume of hydrogen gas evolved was observed as concentration of extract increases. Result from the weight loss shows similar trend of inhibitory behaviour for the weight loss method as the weight loss experienced by the coupons reduces as extract concentration increases. The Taffel plot for the extract indicates good inhibitive properties with inhibition efficiency increasing with extract concentration. In all the three methods studied, the maximum inhibition efficiency was observed in the 50% extract concentration. The extract fits best into the Freundlich isotherm indicating physisorption. This study showed that this particular plant extract is an effective inhibitor in suppressing the corrosion on the surface of the metal.

Excited-state quenching improved with the length of the conjugated chain structure. Pro-vitamin A activity was dependent on the presence of at least one beta-ionyl ring structure. The effectiveness of carotenoids as antioxidants depended on their ability to trap peroxyl radicals with production of resonance-stabilized carotenyl radicals. The products identified from oxidations of carotenes and xanthophylls with molecular oxygen and other oxidizing agents are presented. The free radical-mediated mechanisms that have been proposed to account for the different classes of products are reviewed.

Fortification of yoghurt with fresh tomato juice has shown to incorporate lycopene into the yoghurt, which in turn, increased the nutritional benefit of the yoghurt. Tomato juice was added as increasing levels of 0, 50, 100, 150 and 200 w/w% to plain yoghurt. Ash, carbohydrate, moisture pH, viscosity and lycopene content were all analyzed using standard methods. Results showed that ash and carbohydrate content of the yoghurt improved in direct proportion with fortification. Lycopene content also increased (1.50-9.24 mg/kg) as enrichment with fresh tomato juice increased. Viscosity reduced drastically as fortification increased, colour and texture of the yoghurt also changed; however, sample B (50% tomato juice) showed the best acceptance in respect to the sensory analysis of all the fortified samples. Hence, findings in this research indicated that enrichment of yoghurt with fresh tomato juice improved the nutritional indices of the yogurt.

The method is easy, eco-friendly and cost-effective. Locally sourced medicinal plant Canna indica was used as capping/ stabilizing agent instead of toxic chemicals. Secondary metabolites in the plant extract acted as reducing agents. Optical measurements were carried out using Uv-vis spectrophotometer and photoluminescence (PL). Formation of core-shell was detected in the TEM micrograph, which was supported by two peaks observed in surface plasmon resonance shown in the Uv-vis spectra. FT-IR spectrophotometric analysis indicated the presence of some specific functional groups in the phytochemicals which were adsorbed on the surface of nanoparticles. This analysis depicted the presence of hydroxyl group (O-H stretching) with a broad strong peak at 3360 cm-1 , C-H stretching at 2938 cm-1 , C=C stretching at 1659 cm-1 , C=N stretching at 1557 cm-1 and CO deformation at 1065 cm-1. Crystalline phase of the nanoparticles was determined using X-ray diffraction (XRD). The plant-mediated green synthesized silver/cobalt nanoparticles are potential optical materials as a result of their broad absorption band and emission.
