摘要
对薄荷迷迭香酸进行提取及分析研究。以干制薄荷叶为原料,采用热回流水浸提与乙酸乙酯萃取相结合的方法提取,以硫酸亚铁比色法和高效液相色谱法分别对提取物中迷迭香酸进行定性、定量研究。结果表明,薄荷中含有迷迭香酸成分,其含量为0.156%。该法准确度高,结果可靠。
This paper studied the extraction and analysis methods of Rosmariuic 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 Rosmariuic 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.
