Figure 2. Results from an experiment comparing a traditional targeted method, or DNA barcoding using universal primers for amplification with our non-target whole sample sequencing. The sample analyzed was a 99:1 (by mass) ratio of VBRM grade Matricaria chamomila to Melissa officinalis. The ‘Traditional Targeted Method’ column is a list of species that were identified by that method. In addition to the vouchered species composing the samples, eight other false positive species were identified. The ‘non-target’ whole sample method shows only the one identification, the species that made up 99% of the total VBRM mix.
