Research Advances in Chemical Components and Applications of Rosmarinus officinalis L.

Rosmarinus officinalis L. is a perennial evergreen subshrub of the family Lamiaceae in the class Dicotyledoneae. It is native to Europe and the Mediterranean coast of northern Africa and has broad development prospects in the food, medicinal, and chemical industries. Although the chemical composition of R. officinalis L. has been reported, the classifications and summary of the structure of its compounds are not sufficient. In this article, we summarize the chemical components of R. officinalis L. that have been reported over the past five years, including flavonoids, terpenoids, and phenylpropanoids, and their structure, and we introduce the applications of R. officinalis L., so as to provide a reference and scientific basis for the chemical composition analysis, structural identification, development and utilization of R. officinalis L..
