Abstract:
Camellia oleifera Abel (commonly abbreviated as COA), a species of the Camellia genus, is a woody oil-bearing tree endemic to China. It has been cultivated and utilized in China for over 2300 years. COA possesses both medicinal and edible value. In recent years, most of the biological research on COA has focused on the development and breeding of new varieties, and the research on economic value has focused on the extraction of high-quality camellia oil. Research on Camellia oleifera Abel polysaccharides (COAPs) remains relatively limited. This paper systematically evaluates the composition, extraction methods, biological activity, and application prospects of COAPs to enhance their quality, stability, safety, and reliability. It specifically examines the impact of different extraction processes on polysaccharide structure. Furthermore, it elucidates the intrinsic relationship between molecular structure and biological function. By summarizing the structure-activity relationship of polysaccharides from different parts of COA, this review lays a scientific foundation for their function-oriented production and application.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
