Authentication of Brazilian Ginseng using Bar-HRM analysis

Descripción
Sumario:Hebanthe eriantha (Martius) Kuntze and Pfaffia glomerata (Spreng) Pedersen are medicinal plants popularly known as “Brazilian Ginseng” due to their similarity to Panax ginseng. In Brazil, they are sold as the same herb, despite their different pharmacological and toxicological properties. The morphological identification is difficult, which facilitates their adulteration. We report the application of the Barcode DNA High-Resolution Melting (Bar-HRM) using matK gene to differentiate both species in samples sold in the Brazilian market. Using the proposed method, we could discriminate and identify both species. Bar-HRM analysis allowed discriminating and identifying both species. It allowed the identification of H. eriantha and P. glomerata in 43.6% and 56.4% of the amplified samples, respectively. Of these, only seven samples were authenticated and, in 71.4% of the cases, adulterated. We concluded that Bar-HRM has proven to be a fast alternative method to authenticate plants under the common name “Brazilian Ginseng”.
