This study provides a detailed bibliometric analysis of research on medicinal plant extracts conducted over the past decade, with a focus on their therapeutic applications. Using the Scopus database, 1105 publications from 2014 to 2024 were analyzed to uncover trends in publication volume, collaboration networks, and research clusters. The analysis revealed a steady annual growth rate of 1.98%, with most studies concentrating on the anti-inflammatory, antimicrobial, and antioxidant properties of plant extracts, particularly those containing bioactive compounds such as flavonoids, alkaloids, and terpenoids. The study also highlighted the increasing international collaborations in the field, with 30.84% of the documents featuring cross-border co-authorship. Leading contributors to this research include India, China, and Italy, whose researchers and institutions have played a significant role in advancing the field. The widespread use of advanced analytical techniques, including High-Performance Liquid Chromatography (HPLC) and Nuclear Magnetic Resonance (NMR) spectroscopy, has enhanced the identification and characterization of bioactive molecules. Keywords such as “plant extract”, “antioxidant activity”, and “phytochemistry” were the most frequently occurring, reflecting dominant research themes. Additionally, the h-index analysis showed that 59 of the documents had received at least 59 citations, highlighting the significant impact of this body of research. The study underscores the growing role of phytochemicals in the development of alternative therapies for chronic diseases such as cancer, diabetes, and neurodegenerative disorders. These findings provide a roadmap for future research, encouraging further exploration of plant-based therapies with an emphasis on sustainability, bioactive compound efficacy, and global collaboration.

The integration of graphene-based materials with metal–organic frameworks (G@MOFs) has emerged as a promising strategy for advanced wastewater treatment owing to their synergistic physicochemical properties. This review systematically compiles and critically analyzes recent advances in the synthesis, structural characterization, and application of G@MOFs for the removal of organic and inorganic micropollutants. Special emphasis is placed on how the unique combination of high surface area, tunable pore structures, and abundant active sites in G@MOFs enhances adsorption, photodegradation, and catalytic degradation mechanisms. Compared to conventional adsorbents and standalone MOFs, G@MOFs exhibit superior removal capacities, stability, and reusability. This paper also identifies key challenges in large-scale applications, regeneration, and potential environmental risks, providing a future outlook on optimizing synthesis routes and tailoring functional composites for sustainable water treatment technologies. The novelty of this review lies in providing the first dedicated, systematic evaluation of G@MOFs for wastewater micropollutant removal, integrating synthesis strategies, performance benchmarking, techno-economic aspects, environmental safety, and future application prospects into a unified framework.

Essential oils (EOs) play an important role in the pharmaceutical, cosmetic, and food industries for their therapeutic and aromatic properties. Selecting the appropriate extraction method is crucial for optimizing yield, quality, and environmental impact. This study uses a multi-criteria decision-making (MCDM) approach with the Analytic Hierarchy Process (AHP) and the Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) ranking method to evaluate and rank EO extraction techniques. AHP determines the weights of evaluation criteria, while PROMETHEE ranks methods based on these weights. All traditional and modern techniques are assessed. Results show that supercritical fluid extraction for modern techniques and steam distillation (SD) for traditional techniques are the most effective methods due to their superior performance across multiple criteria. This framework provides insights into selecting optimal extraction methods tailored to industrial needs. The study emphasizes the importance of a systematic approach in selecting extraction methods, highlighting the high yield and quality preservation of supercritical fluid extraction, as well as the efficiency and cost-effectiveness of SD. It underscores the need for industries to consider various criteria, including environmental impact and safety, in their decision-making processes. Future research should refine these techniques and explore new methods to enhance the efficiency and sustainability of EO extraction.
