Although Danggui is the root of Angelica gigas NAKAI in the Korean Pharmacopoeia, it is determined that Danggui is also the root of Angelica sinensis (OLIV.) DIELS in China and Hong Kong, as well as the root of Angelica acutiloba KITAGAWA in Japan. Accordingly, we tried to develop an identification method using the main compounds in A. gigas, A. sinensis, and A. acutiloba through HPLC/diode-array detector (DAD). This method was fully validated for linearity, accuracy, precision, recovery, and robustness. Multivariate analysis was also implemented after pattern analysis and monitoring. As a result, each compound pattern of A. gigas, A. sinensis, and A. acutiloba was identified, making it possible to distinguish them from each other.
