Ultrasound-assisted hydrophobic deep eutectic solvents combined with macroporous resins for the extraction and recovery of triterpenoids from Forsythiae Fructus

Can sound waves and eco-friendly solvents unlock the hidden medicinal power of a traditional Chinese fruit? This study says yes—using a clever combination that extracts triterpenoids faster and cleaner than ever before.

Forsythiae Fructus, a staple in traditional medicine, holds triterpenoids with promising bioactivity. But getting them out is tricky. Conventional methods are slow and use harsh solvents. This research flips the script by pairing ultrasound-assisted hydrophobic deep eutectic solvents—a new class of green solvents—with macroporous resins. The ultrasound provides intense, localized energy to break plant cell walls, releasing the target compounds efficiently. The hydrophobic NADES then selectively captures these triterpenoids. The macroporous resins act as a recovery sponge, allowing the valuable compounds to be separated and collected, while the solvent can be reused. This synergy not only boosts extraction yield but also simplifies purification. The result is a more sustainable, scalable process that could replace traditional petroleum-based methods. It's a win for both green chemistry and natural product research.

Key Points

• Ultrasound boosts extraction efficiency from plant cells.
• Green NADES selectively capture triterpenoids.
• Macroporous resins enable easy recovery and reuse.
