Specific primers for amplifying DNA extracted from the crude drugs of Pheretima. DNA was amplified using specific primers, (a) primers MF2R2 for Metaphire genus and (b) primers AF3R1 for Amynthas genus, respectively. Adulterant numbered P15 could also be amplified using primers AF3R1, but with sequence and BLAST to the adulterant. PCR without DNA template was used as negative control (N). M:DNA ladders
