Optimizing Green Extraction Methods for Maximizing the Biological Potential of Dandelion, Milk Thistle, and Chamomile Seed Extracts.

ABSTRACT: This study investigates the underutilized potential of agri-crops from the Asteraceae family by employing sustainable and green technologies (supercritical fluid, ultrasound, and Soxhlet extractions) to enhance the recovery of bioactive compounds. A total of 21 extracts from native and waste seeds of dandelion, milk thistle, and chamomile were systematically compared utilizing a combination of solvents (supercritical CO₂ and absolute or aqueous ethanol). Supercritical CO₂ extraction yielded up to 281 mg/g of oils from native seeds, while conventional techniques with ethanol recovered an additional 142 mg/g of extracts from waste seeds. Notably, waste seed extracts exhibited superior biological activity, including potent antioxidant properties (IC₅₀ v
