Green extraction of natural products: A bibliometric review of global research trends, technological advances, and environmental implications

• A sharp rise in publications after 2015 related to techniques like supercritical fluid, ultrasound-assisted, and enzymatic extraction. • China, India, and Brazil lead in publication volume, while European countries contribute more highly cited, high-quality research. • Trends in Food Science & Technology and Food Research International are highlighted as leading journals shaping green extraction research • Major challenges include scalability and regulatory issues; future research is expected to focus on industrial integration, AI-based optimization, and circular economy applications. The increasing demands for environmentally sound and sustainable extraction methods have prompted an increasing demand for green extraction technologies for natural products. This bibliometric analysis investigates the research trends, lead researchers, and emerging methodologies of green extraction from 2004 until the last search conducted on 16 th February 2025. In relation to a summary of 140 Scopus-indexed articles, the current study finds an increasingly large body of research in recent years with a maximum increase after 2015 following advancements in different techniques such as supercritical fluid extraction, ultrasound-assisted extraction, and enzymatic extraction. China, India, and Brazil lead in terms of publication volume, whereas European countries have higher citation influence, reflecting their contribution to the production of high-quality research. Flagship journals such as Trends in Food Science & Technology and Food Research International play a crucial role in the advancement of research in this field. Despite significant strides, issues such as scalability, regulatory harmonization, and stability of extracted bioactive compounds continue to face researchers. Future research would have to be focused on industrial integration, artificial intelligence-based optimization, and broader applications in the circular economy. Green extraction technologies are on the verge of transforming waste valorization, enhancing bioavailability, and facilitating environmentally friendly industrial processes.
