No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of decursin, decursinol angelate and demethylsuberosin, with LC-MS identity. Full testing to the USP Herbal Medicines Compendium monograph for Angelica gigas Root is available and quoted.
Angelica gigas is rich in decursin and decursinol angelate, which are low or absent in Angelica sinensis (dong quai) and Angelica acutiloba. The monograph lists these species as potential confounding materials.
They are isomers with the same mass, so they are separated chromatographically and identified by retention time against reference standards.
