摘要

The seeds of Camellia oleifera are utilized to produce high-quality edible oil, which have a wide range of applications in the realms of medicine, health supplements, and personal care products. However, the residue left after oil extraction, namely C. oleifera seed cakes (COSCs), remains an unexploited resource. COSCs are endowed with lots of bioactive constituents (BCs) such as flavonoids, saponins, polysaccharides, and proteins, which have a wide range of health benefits both in vivo and in vitro. In this comprehensive review, alternative extraction techniques for recovering these bioactive compounds from COSCs were explored. Both traditional and innovative methodologies have been employed to extract these high-value substances from COSCs. The merits and demerits of various extraction processes have been meticulously scrutinized. Additionally, a comprehensive overview of biological properties of COSCs was provided, and their current applications and development in the food and pharmaceutical industries were detailed. The challenges and future prospects pertaining to the effective utilization of COSCs have been identified and discussed.
