Morphological similarity within species makes the identification and authentication of species challenging, especially in dietary supplements that contain processed root or leaf powder of different sage species. In the present study, the species discriminatory power of 2 potential DNA barcode regions from the nuclear genome was evaluated in 7 medicinally important species from the family Lamiaceae. The nuclear internal transcribed spacer 2 and the exon 9 - 14 region of low copy nuclear gene coding for granule-bound starch synthase 1 were tested for their species discrimination ability using distance, phylogenetic, and BLAST-based methods.
