Metal-organic frameworks (MOFs), a crystalline material, are a new type of inorganicorganic hybrid material. MOFs are of great interest to researchers in chemistry and material science due to their various chemical and physical properties, and features include their remarkable surface area, high porosity, flexibility, structural variety, flexibility, extreme porosity, a large surface area, augmented adsorption/desorption kin Read More

An immediate and precise diagnosis is required due to the COVID-19 outbreak. Labelfree electrochemical biosensors show promise as potentially valuable instruments for detecting COVID-19. These biosensors are distinguished by their lack of complexity, high speed, sensitivity, and relatively low cost. The precise COVID-19 biomarkers may be recognized without labeling or amplification by detecting the electrical signal create Read More

Background: Oxidative damage to biological molecules is mainly caused by free radicals produced in the body. Natural antioxidants can prevent the resulting oxidative stress. For this purpose, particularly grapes and grape products, which contain vitamins and polyphenolic substances with high antioxidant activity, are used. Methods: In the present study, the content of vitamins C and E, beta-carotene, and some flavonoids (+)-c Read More

Introduction: Cherry-red tobacco is a flue-cured variant that possesses a distinctive “sticky rice” flavor, which is highly valued by the tobacco industry. However, the value of cherryred tobacco is dubious due to the possible health risks associated with tobacco-specific nitrosamines (TSNAs). Objective: This study aimed to investigate the chemical origin of the “sticky rice” flavor and to assess the potential health hazards of TS Read More

Background: Rutin is a natural flavonol that showed excellent antiglycation activity with an IC50 value of 294.5 ± 1.5 μM. In the current study, three selected plant species of Euphorbia, i.e., Euphorbia helioscopia, Euphorbia larica, and Euphorbia wallichii, were analyzed for the quantification of rutin. Methods: The quantification was done through a newly developed method of Emission spectroscopy coupled with Partial Least Squ Read More

Background: Scutellariae Radix, one of the most widely used herbs in Traditional Chinese Medicine, exhibits various biological activities due to its chemical components, which stand out for a number of flavonoids. In this study, Ultrasound-assisted aqueous two-phase extraction (UAATPE) was employed for the first time to obtain a high extraction rate and high purity of flavonoids from Scutellariae Radix. Methods: The Box-Behn Read More
