Quantitative analysis of coumarins in Artemisia keiskeana and A. stolonifera using HPLC/PDA

Abstract

Artemisia keiskeana and A. stolonifera are plants of the genus Artemisia, distributed in various regions, especially China and Korea. They are renowned as medicinal plants with biological and pharmacological activities. Fraxidin, isofraxidin, and daphnoretin are coumarins present in Artemisia spp.; however, research on them is limited. Therefore, this study was carried out to quantify the content of these compounds in the aerial parts of A. keiskeana and A. stolonifera in different regions in Korea. High-performance liquid chromatography was performed with a photodiode array detector and a reverse-phase INNO column. A. stolonifera only contained fraxidin with the highest amount found in Yongmun commune. A. keiskeana cultivation in Soyang commune gave the highest fraxidin and daphnoretin content. However, isofraxidin was not present in all samples. The findings suggest that the concentrations of the three compounds may differ depending on the growth site and provide a foundation for future studies. © The Korean Society for Applied Biological Chemistry 2023.
