Conventional and modern techniques for bioactive compounds recovery from plants: Review

How do we capture the hidden health benefits locked inside plants without harming the planet? The answer lies in a major green revolution in how we extract nature's most valuable chemical compounds.

Plant-derived phytochemicals are capturing global attention for their diverse health benefits and industrial applications. Historically, scientists relied on traditional extraction methods, but a wave of innovation is changing the game. New procedures are being specifically developed to harvest these valuable chemicals from various biomasses much more ecologically.

Modern extraction techniques are stepping up to the plate. Methods like supercritical fluid extraction, microwave-assisted extraction, ultrasound-assisted extraction, instant controlled pressure drop, pressurized liquid extraction, and negative pressure cavitation are proving their worth. They deliver improved yields, slashed solvent usage, and a much lighter environmental footprint.

Looking at the bigger picture, pairing these extraction methods with biorefinery concepts unlocks exciting circular economy approaches. This review dives into these recent advancements, offering a critical look at green extraction in natural product chemistry to boost both efficiency and eco-sustainability.
