High-Pressure Extraction Techniques for Efficient Recovery of Flavonoids and Coumarins from Flower Seeds

What if the humble sunflower seed held a hidden treasure of health-boosting compounds, locked away until now? High-pressure extraction is the key to unlocking it.

Flower seeds are more than just potential plants—they are reservoirs of bioactive molecules like flavonoids and coumarins, which are linked to various health benefits. Yet, these seeds have long been underutilized in the quest for natural compounds. Traditional extraction methods often rely on harsh solvents and yield subpar results. Enter high-pressure techniques: supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE). These methods offer a greener, more efficient path, reducing harmful solvent use while boosting yield and purity. Think of them as precision tools, using temperature, pressure, solvent choice, and time to coax out the best from seeds like calendula and sunflower. This review dives deep into how these parameters influence the quality and quantity of the extracted compounds, aiming to optimize protocols for sustainable, efficient recovery. The goal? A comprehensive understanding that turns underappreciated seeds into a viable source of valuable bioactives.

Key Points

• High-pressure methods (SFE, PLE) are greener and more efficient.
• Flower seeds like calendula and sunflower are rich sources.
• Optimizing parameters boosts yield and purity of bioactives.
