title: Application of sequence characterized amplified region (SCAR) analysis to authenticate Panax species and their adulterants.
abstract: A 420-bp RAPD fragment from Panax quinquefolius was converted to a sequence characterized amplified region (SCAR) marker. The main difference between the SCAR of P. quinquefolius and its homolog in P. ginseng is the presence of a 25 bp insertion in the latter. Primers derived from this sequence were successfully used to authenticate six Panax species and two common adulterants.
