Valorisation, Green Extraction Development, and Metabolomic Analysis of Wild Artichoke By-Product Using Pressurised Liquid Extraction UPLC–HRMS and Multivariate Data Analysis

Every year, mountains of artichoke leaves, stems, and roots are thrown away—but hidden inside this waste lies a treasure trove of health-boosting chemicals. Now, scientists have found a green way to unlock it.

This work not only highlights the untapped potential of artichoke by-products but also demonstrates how green chemistry can transform industrial leftovers into valuable ingredients. The next time you see an artichoke, remember: its leaves might just hold the future of sustainable nutrition.

Key Points

• Artichoke waste is rich in phytochemicals like phenolic acids and flavonoids.
• Green pressurised-liquid extraction yields antioxidant-rich extracts.
• Multivariate analysis optimizes solvent choice for extraction.
