This study investigated the physicochemical properties and antioxidant activity of Bambusa tulda tea. The tea exhibited low moisture and ash content, indicative of good drying quality. Its acidic pH was attributed to the presence of organic acids. Phytochemical analysis confirmed the presence of carbohydrates, reducing sugars, triterpenoids and cardiac glycosides. The dry extract contained higher levels of phenolics and flavonoids compared to the infusion, resulting in stronger antioxidant activity, as demonstrated by a lower IC50 value of 3.794 in the DPPH radical scavenging assay. Furthermore, silica (SiO₂) was extracted from the tea leaves and characterized using X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). These analyses revealed an amorphous structure and spherical morphology. Field Emission Scanning Electron Microscopy (FE-SEM) and Energy Dispersive Spectroscopy (EDS) analyses corroborated the spherical morphology and elemental composition of the SiO₂. The extracted SiO₂ effectively degraded methylene blue and Congo red dyes under sunlight, highlighting the potential of B. tulda tea as a sustainable source of SiO₂ for environmental remediation.
Herbal tea has a long history in India and is made from various plant parts, including leaves and flowers. India has a rich variety of bamboo species. Bamboo leaves are used in some parts of the world, especially Asia, to make a mild and aromatic tea with potential health benefits. This review evaluates existing research on bamboo leaf tea, including the different bamboo species used, their chemical makeup and their antioxidant properties. The analysis of five studies covering nineteen bamboo species revealed that brewing methods impact the tea's chemical composition. All studies found phenols and flavonoids, suggesting health benefits. Strong antioxidant activity was confirmed through DPPH and FRAP assays, and this activity is further boosted by fermentation, as with kombucha, which increases the availability of beneficial compounds and adds helpful microbial byproducts. Bamboo leaf tea, being a sustainable and underutilized resource, offers potential for addressing some global health and environmental issues. This review summarizes the scientific evidence supporting the health benefits of bamboo leaf tea and discusses its potential in the development of new functional foods and drinks.
Diabetes mellitus and dyslipidemia make a significant contribution to mortality and morbidity. The Gymnema Sylvestre’s saponins have a variety of pharmacological effects, including the possibility of lowering diabetes and cholesterol levels. In the present study, molecular docking and molecular dynamic simulations were used in silico in order to understand the protein league stability and molecular interactions by aiming at anti-diabetic and anti-lipidemic proteins. As well we performed the drug likeliness and its toxicity of 13 G. sylvestre saponins, against anti-diabetic target proteins Aldose reductase, α- amylase, α- glycosidase and antilipidemic target proteins HMG-CoA reductase, Fatty acid synthase, Pancreatic Lipase target proteins. Gymnemasin B and Gymnema saponin– IV were shown the high energy between the target protein. As well these compounds shown good ADMET properties with standard oral antidiabetic compound Linagliptin. Molecular dynamics simulations further supported their strong binding interactions with the target proteins over time using 100 ns MD simulations. These findings suggest that these saponins hold promise as potential active molecules to making them possible candidates for the development of novel therapies for diabetes mellitus.
In view of the current study's demonstration of the synthesis of clay-doped ZnO composites, we present a low-cost method for producing clay-metal oxide (clay/ZnO). Utilizing the solution combustion technique, a composite of clay/ZnO was produced utilizing citric acid as both a fuel and a complexing agent. The hexagonal unit cell structure of the created clay/ZnO may be seen using XRD patterns. The ZnO-infused clay was visible in FE-SEM micrographs as homogenous, sphere-shaped ZnO. The possible involvement of clay/ZnO photocatalytic activity in the UV-induced photodegradation of malachite green dye was investigated. The 90% degradation rate shows the composite's outstanding photocatalytic degradation capacity. The resulting substance was electrochemically analyzed using a constructed electrode in 0.1 M KOH electrolyte. It increased its sensor capabilities, which now include chemical and biomolecule sensors, and it excelled in cyclic voltammetry-based redox potential studies. To efficiently evaluate chemically synthesized NPs for electrochemical, sensing, and photocatalytic applications, this study intends to create a solution combustion procedure for the synthesis of clay/ZnO nanocomposite using urea as fuel.
Diabetes mellitus (DM), a chronic medical condition, has attained a global pandemic status over the last few decades affecting millions of people. Despite a variety of synthetic drugs available in the market, the use of herbal medicines for managing diabetes is gaining importance because of being comparatively safer. This article reviews the result of a substantial literature search on polyherbal formulations (PHFs) developed and evaluated with potential for DM. The accumulated data in the literature allowed us to enlist 76PHFs consisting of different parts of 147 plant species belonging to 58 botanical families. The documented plant species are laden with bioactive components with anti-diabetic properties and thus draw attention. The most favoured ingredient for PHFs was leaves of Gymnema sylvestre and seeds of Trigonella foenum-graecum used in 27 and 22 formulations, respectively. Apart from herbs, shilajit (exudates from high mountain rocks) formed an important component of 9 PHFs, whereas calcined Mytilus margaritiferus and goat pancreas were used in Dolabi, the most commonly used tablet form of PHF in Indian markets. The healing properties of PHFs against diabetes have been examined in both pre-clinical studies and clinical trials. However, the mechanism(s) of action of PHFs are still unclear and considered the pitfalls inherent in understanding the benefits of PHFs. From the information available based on experimental systems, it could be concluded that plant-derived medicines will have a considerable role to play in the control of diabetes provided the challenges related to their bioavailability, bioefficacy, optimal dose, lack of characterization, ambiguous mechanism of action, and clinical efficiency are addressed.
