A New Method for Identification of Ginseng Radix et Rhizoma Adulterated with Panacis Quinquefolii Radix.

ABSTRACT: In the regulatory market, it is not uncommon for ginseng radix et rhizoma (GR) to be adulterated with panacis quinquefolii radix (PR). Amid the digital transformation, this study puts forward a new method for the identification of GR adulterated with PR. Ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was used to detect multiple batches of GR and PR to obtain mass spectrometry data. The common ions were isolated from multiple batches of GR and PR, serving as GR and PR's "ion matrices". Furthermore, GR and PR's "ion matrices" were used to eliminate intersecting ion data to extract the top-100 ions as GR and PR "matrix identity cards" (MICs). Then, GR and PR's MICs were employed as a reference for identification, yielding contrast credi
