From: Determination of ITS1 haplotypes of Fritillariae Cirrhosae Bulbus by amplicon sequencing
PCR–RFLP of genuine and non-genuine Fritillaria species. All six genuine species could be successfully amplified and digested, with weak 300-bp bands remaining uncut. The non-genuine samples were either not amplified or produced a ~ 300-bp band that was only weakly digested. RD176 and T5177 were chosen as extraction positive controls and were extracted together with the samples in different rounds of extractions
