肉桂为我国传统常用中药材，主要分布于热带地区，道地产区包括我国广东、广西2省和越南部分地区。肉桂中化学成分类型丰富，包括挥发油、黄烷醇类、萜类、木脂素类、酚酸类、多糖类等成分，传统认为肉桂挥发油中的桂皮醛和桂皮酸为其主要药效成分。对肉桂资源、化学成分、主要药理活性进行总结，并在此基础上，分析挥发油、多酚类、二萜类等成分与药效的关系，分析生源途径、传统功效、现代药理作用与化学成分之间的关系。建议对肉桂进行挥发油、多酚类、黄烷醇类、二萜类等成分的定性、定量分析，进一步聚焦其中多酚类、黄烷醇类和萜类等成分化学物质组的深入研究，为明确肉桂的质量标志物（Q-marker）和制定科学的质量标准提供基础。

Cinnamomum cassia, a well-known traditional Chinese medicine, is mainly distributed in tropical areas. Its genuine producing areas contain Guangdong Province, Guangxi Province and parts of Vietnam. The chemical composition is rich in C. cassia, including volatile oil, flavanol, terpenoids, ligans, phenolic acids, polysaccharides, etc. Traditionally, cinnamaldehyde and cinnamic acid from volatile oil are its main effective components. In this paper, the resource, chemical composition and main pharmacological activities of C. cassia were summarized. And on this basis, the relationship between chemical components and drug efficacy, including the volatile oil, polyphenols, flavanol, and diterpenoids, as well as the relationships between biogenetic ways, traditional efficacy, modern pharmacological effects and chemical composition were analyzed. It is suggested that identification and quantification of volatile oil, polyphenols, flavanol and diterpenoids should be carried out and the further research of the chemical group of polyphenols and terpenoids from C. cassia should be focused, which could provide basis for clarifying the quality marker (Q-marker) and establishing scientific quality standards of C. cassia.
