Extraction techniques of saponins have evolved, transitioning from traditional methods such as maceration and reflux extraction to newer, more environmentally friendly methods, including ultrasound-assisted extraction, microwave-assisted extraction, supercritical fluid extraction, and deep eutectic solvent extraction. Fermentation-based techniques are also emerging as sustainable alternatives. Saponins possess remarkable anti-inflammatory, anti-tumor, and antioxidant properties, making them valuable in the management of chronic diseases such as diabetes, cardiovascular disorders, and cancer. Additionally, they enhance vaccine efficacy and bioavailability of drugs that act as adjuvants and nanocarriers. Their applications extend to cosmeceuticals as skin-friendly cleansers and anti-aging agents, to the food industry as natural preservatives and emulsifiers, and to agriculture, where their anti-fungal and immunomodulatory properties protect crops.
