Abstract: This paper studied the extraction and analysis methods of Rosmarinic acid in the Mentha haplocalyx Briq.The dry leaves of Mentha Haplocalyx Briq were used as raw material. By hot refluxing water and ethyl acetate Rosmarinic acid was extracted. Colorimetry was adopted to conduct qualitative analysis. High performance liquid chromatography (HPLC) was used to determine Rosmarinic acid content. The results showed that Rosmarinic acid in the Mentha haplocalyx Briq was identified and its content was 0.156%. This assay method was precise and reliable.

Key words: mentha haplocalyx Briq, rosmarinic acid, extraction, analysis
