Development of a highly discriminatory method for the identification of genotypes and species of medicinal plants regulated by the Brazilian public health system (SUS) is of paramount importance for the quality control of these species as raw material in the production of herbal medicines in order to minimize the health risks associated with ineffective therapy using raw materials of uncertain identity. We used RAPD-PCR to generate genetic profiles of three medicinal plant species regulated by SUS in Brazil, Mikania glomerata, Maytenus ilicifolia, and Schinus terebinthifolius, from the specimens of these plants donated by the Theme Collection of Medicinal Plants of the Instituto de Pesquisas do Jardim Botânico do Rio de Janeiro. The 60 arbitrary primers used for RAPD-PCR with DNA from the three species generated 1284 amplified products ranging from 100 to 1500 bp. Five primers generating a total of 76 fragments between 200 and 1100 bp from the three species were selected: OPG18, OPA7, and OPG17 for Mikania glomerata; OPG20, OPC13, and OPA11 for Maytenus ilicifolia; OPA4, OPA18, and OPG14 for Schinus terebinthifolius; and OPA17 and OPC6 for the three species. The profiles generated allowed the effective discrimination of the species. Primers were identified that generated a single fragment that can serve to determine a specific marker for use in the identification of plant products either in isolation or in association.
