UHPLC-PDA method for monitoring catechins and caffeine in tea samples and assessment of postharvest-associated variability across multilocation samples Anmol, Sumit Thakur, Aryan Bhardwaj, Sahil Awasthi, Aadarsh Shrivastav, Pramod Kumar, Mohit Sharma, Upendra Sharma Journal of Food Composition and Analysis, 2026 Herein, UHPLC coupled to a PDA-based quantification method has been developed for the simultaneous analysis of eight major catechins, namely gallocatechin, epigallocatechin, catechin, epicatechin, epigallocatechin gallate, gallocatechin gallate, epicatechin gallate, and catechin gallate, as well as caffeine. The developed method was validated using linearity studies, detection and quantification limits, accuracy studies, theoretical plate count, asymmetric factor, tailing factor, and resolution, demonstrating its reliability and efficiency for analysing the chemical composition of tea samples. To maximize overall yield, the extraction protocol was optimized by varying solvent type, extraction method, duration, and temperature variation. The developed method has been applied to investigate multilocation's and postharvest influence on caffeine and catechin content in tea leaves collected from seventeen different locations. A wide chemical diversity was observed among the samples; for example, among eight samples from Himachal Pradesh, caffeine content ranged from 13.97 to 23.25 mg/g, while catechin content ranged from 4.76 to 110.10 mg/g. Results highlighted the need for stringent protocols for post-harvest handling of unprocessed teas to avoid autooxidation during comparative analysis. Further, the developed method was applied to various marketed teas, demonstrating its efficacy for quantifying tea metabolites across diverse matrices. • UHPLC-PDA method for the simultaneous quantitative analysis of eight tea catechins and caffeine. • Method development and validation as per ICH guidelines. • Extraction procedure and solvent optimization for improved recovery. • Efficacy of the developed method for quantifying metabolites across marketed teas. • Multilocation tea leaf samples analysis to assess phytochemical variability.

Preface New Generation Advanced Materials for Regenerative Development, 2026
Novel Materials in Water Pollutant Ion Sensors Shibashis Halder, Sudheer Kumar Yadav, Kumari Seema, Abhijeet Ghosh, Deepika Dimri, Anshu Kumar, Pramod Kumar, Ambika Kumar New Generation Advanced Materials for Regenerative Development, 2026 Water is a basic and mandatory requirement for the entire living creatures on the earth including human. Hence, the consumption of water by human should be safe, adequate, easily accessible, and free from any kind of contamination. Owing to various anthropogenic activities, many heavy metal ions have been constantly discharged in improper way, which prominently cause deadly effects on the water bodies and lead to chronic diseases. Thus, in order to assure human health via food safety and to minimize significant risks, it is crucial now to monitor hazardous pollutants present in water resources frequently. Various techniques have been employed to monitor water quality so far and sensing technique has been emerged as a promising method due to its inherent properties, e.g., selectivity, sensitivity, simple operation, and in-situ detection. This chapter provides a critical assessment of the applicability of various novel materials for real-time water quality monitoring, focusing on those that have been reportedly tested in real-life scenarios. The brief information on various specific techniques like electrochemical, colorimetric, fluorescence, and biosensing has been discussed. It also emphasizes the importance of materials in developing sensors in terms of their specific structural, optical, chemical, and electrical properties.
Waste-derived nanocomposites powering the future: Biochar@Fe2O3 anodes in microbial fuel cells Soumya Pandit, Pramod Kumar, Soumyajit Chandra, Elvis Fosso -Kankeu, Richa Tomar Nano Trends, 2025 This research presents the combination of chir pine-derived biochar and petunia-derived ferric oxide (Fe 2 O 3 ) as nanocomposites acting as catalysts for the anode, enhancing the functionality of a microbial fuel cell (MFC). Improved microbial activity and electron transport were the aim of this combination. The nanocomposite was examined using a variety of techniques, such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The synthesised nanocomposites were used as a catalyst on the anode electrode. The anode with nanocomposite showed an improved performance compared to the unmodified or bare anode and the anode with only biochar. The charge-discharge study, polarisation study, cyclic voltammetry, electrochemical impedance spectroscopy, Coulombic efficiency, and other techniques were used to accomplish the electrochemical investigation. The testing results showed significant improvements in power density of up to 13.32 W/m 3 , highlighting the composite’s potential to boost MFC efficiency. The improved biofilm formation was observed using increasing concentrations of biochar@Fe 2 O 3 nanocomposites. The energy recovered as bioelectricity was around 16.34%. Owing to the abundance of Chir Pine biomass and iron-rich Petunia plants, this green-synthesized nanocomposite offers a low-cost and scalable approach for simultaneous wastewater treatment and clean energy generation, aligning with circular economy and sustainability goals.
Sustainable photocatalytic approach: Natural sunlight-driven Degradation of β-naphthol by solution-Free CeO2-ZnO nanocomposite Priyanka Madhu, Khushboo Dasauni, Preeti Joshi, Tapan Kumar Nailwal, Pramod Kumar, Bhavani Prasad Naik Nenavathu, Ambika Kumar Sustainable Chemistry for Climate Action, 2025 This work explores the fabrication and analysis of CeO 2 -ZnO nanocomposites (CZ NCs) using a simple, economical, and solution-free method for preparation, promoting sustainable chemistry by eliminating solvents, reducing waste, and minimizing environmental impact. X-ray diffraction (XRD) analysis of CZ NCs revealed a decrease in crystallite sizes with an increase in Ce (IV) ion concentration. Field Emission Scanning Electron Microscope (FE-SEM) observation indicated that modification of Zinc Oxide nanoparticles (ZnO NPs) with the incorporation of Ce (IV) ions results in the formation of cuboidal structures. The polycrystallinity of the material was confirmed by High-Resolution Transmission Electron Microscopy (HRTEM). The Diffused Reflectance Spectrum (DRS) analysis of 5 wt% (or 05:95 for CeO 2 :ZnO) CZ NCs resulted in a narrowing of the band gap from 3.15 eV to 3.04 eV. The surface area analysis revealed an increase from 30.86 m²/g for ZnO NPs to 48.91 m²/g for 5 wt% CZ NCs. Under natural sunlight, 5 wt% CZ NCs exhibited remarkable photocatalytic performance, breaking down 91% of β-naphthol in an aqueous solution within just 20 min at a 0.8 mg/mL concentration. Scavenger tests confirmed hydroxyl radicals (⋅OH) as key contributors to pollutant degradation. The reusability assessment of CZ NCs demonstrated their stability across three successive cycles. The disc diffusion assay was employed to assess the activity of antibacterial targeting Staphylococcus aureus MTCC 737 , revealing that 5 wt% CZ NCs exhibited enhanced antibacterial efficacy compared to ZnO NPs. The present approach helps to achieve cleaner water and reduced microbial contamination, supporting sustainable environmental remediation.
EGCG/ECG-controlled mesoporous and ultrafine TiO₂ nanoparticles for UV-driven pollutant mineralization and radical scavenging Sumit Thakur, Jyoti Gaur, Anand Somvanshi, Suhas Ballal, Kishor Kumar, Kasim Sakran Abass, Pramod Kumar, Sandeep Kaushal, Sanjeev Kumar Scientific Reports, 2025 We report the first phytochemical-guided, one-pot sol–gel/hydrothermal synthesis of mesoporous anatase TiO 2 nanoparticles (< 10 nm) directed by catechin-rich fractions (epigallocatechin-3-gallate (EGCG), epicatechin-3-gallate (ECG), epigallocatechin (EGC)) identified through GC–MS of a TV-26 Camellia sinensis extract. These small-molecule bio-templates drive uniform Ti 4 ⁺ nucleation, arrest crystal growth, and remain grafted to the oxide surface, producing a high specific surface area (160 m 2 g −1 ) and a stable polyphenol corona. Comprehensive characterization (XRD, UV–Vis-DRS, FTIR, BET, SEM/TEM) confirms the phase-pure anatase and a narrow size distribution (6–9 nm). The bio-templated TiO 2 attains > 98% mineralization of methylene blue under near-UV irradiation (365 nm, 65 mW cm⁻ 2 ) within 45 min, giving a pseudo-first-order rate constant k = 0.0567 min −1 , more than double that of commercial P25 under identical conditions. Surface-bound catechins impart intrinsic antioxidant activity, with IC₅₀ values of 34.7 ± 1.2 µg mL −1 (DPPH) and 29.3 ± 0.9 µg mL −1 (ABTS). By uniting green synthesis, size-controlled mesoporosity, and dual photocatalytic/radical-scavenging functionality, this work positions phytochemical-engineered TiO 2 as a versatile platform for next-generation water remediation and biomedical technologies.
