Abstract
Quantitative analytical method by means of high-performance liquid chromatography (HPLC) has been developed for the quality control of Shazenso (Plantago asiatica L.) extracts. Plantaginin (I) which is one of the known constituents of Shazenso, was selected as a standard compound of the analysis. A chemically labile component has been isolated from the methanol extract and identified to be plantamajoside (II). It was found that II was converted into III even in hot water.
