Metabolic profiling of B. aristata, along with its common adulterants/contaminants/substituents such as B. asiatica, Mahonia borealis and Coscinium fenestratum, was rapidly carried out using direct analysis in real-time mass spectrometry (DART MS) to generate the chemical fingerprints for the differentiation of these species. Phytochemical analysis showed the presence of mainly alkaloids. The identified alkaloids were berberrubine, berberine, jatrorrhizine, ketoberberine, palmatine, Dihydropalmatine or 7,8-dihydro-8-hydroxyberberine, berbamine and pakistanamine. Berberine, which was mainly reported from the root and stem bark of B. aristata, was also identified in the leaf along with chlorogenic acid. The DART MS data have been subjected to principal component analysis (PCA). The resulting score plots showed clustering and clear differentiation of the species and plant parts.
