This article reviewed the relevant literature on the main active substances and functions of jasmine (Jasminum sambac (L.) Aiton). The results showed that: 1. The main active substances in jasmine are volatile oil, polysaccharides, and flavonoids. Volatile oil is a mixture of large molecules; Polysaccharide is a type of heteropolysaccharide or sugar complex; Flavonoids mostly exist in the form of glycosides and have multiple monomers. 2. Jasmine flower has various functional activities such as antioxidant, antibacterial, anti-tumor, anti-inflammatory, etc., which are related to active substances such as flavonoids, polysaccharides, and volatile oil. 3. The active function of jasmine is closely related to the advanced structure and certain chemical components of the active substances. The article aims to provide the theoretical and necessary basis for further exploration of active substances in jasmine flowers and the development of jasmine new products.
