Unlocking Agave bracteosa Saponins: Optimized green extraction through Box-Behnken design

What if a humble agave leaf could yield powerful bioactive compounds with just sound waves and a splash of ethanol? Scientists have now fine-tuned a green extraction method that does exactly that.

Ultrasound-assisted extraction (UAE) is shaking up the way we recover bioactive compounds from plants—literally. By using sound waves, it offers an eco-friendly and efficient alternative to traditional methods. In this study, researchers turned to Agave bracteosa leaves, aiming to optimize UAE conditions for maximum saponin yield. Saponins are natural compounds with potential health benefits, and getting them out of plants efficiently is no small feat.

Key Points

• Optimal UAE: 71% ethanol, 34°C, 5 minutes
• Saponins identified via UPLC-QTOF/MSE analysis
• Method repeatable across Agave species
