No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of berberine and palmatine, with LC-MS identity. Full testing to the USP Herbal Medicines Compendium monograph for Berberis aristata Stem is available and quoted.
A berberine result alone does not show its source. Berberis aristata stem also contains palmatine and other alkaloids, so a product with berberine but none of the companion alkaloids can point to added berberine salt.
The monograph lists Berberis asiatica, Berberis lyceum, Coscinium fenestratum and Hydrastis canadensis as potential confounding materials. The alkaloid profile and botanical characters help tell them apart.
