Specific primer pair DZF1/R1 amplification from extractives. Note: Except for the lanes marked M (marker) and CK (negative control), the remaining 20 lanes contain PCR products from 1 to 20 were Lonicerae japonicae Flos extracts amplified by DZF1/R1. All the order is the same as Table 1, and 2, 3, 5, 7–11, 14, 15 were represented the result that Eucommiae Folium can be detected through specific primer pair DZF1/R1.
