Abstract
|
|
|
|
This paper is intended as an investigation of the method of extraction and the analysis by high-performance liquid chromatography mass spectroscopy of decursin and decursinol angelate in the dried root of Angelica gigas Nakai. The extracted decursin and decursinol angelate were the purity of ＞95% using 60% ethanol at -20℃ for 12 hours by HPLC analysis. Decursin and decursinol angelate were efficiently isolated using recycling HPLC. The purity of isolated decursin and decursinol angelate was identified as 99.97 and 99.40% by HPLC analysis, respectively. The molecular weights of Decursin and decursinol angelate were also identified as m/z=329 ([M+H]?) and m/z=351 ([M+Na]?) by mass spectroscopy.
