ABSTRACT
A pair of species-specific primer (GZG1/GZG2) based on COâ
sequence regions for identification of Gekko chinensis were designed. A fluorescent quantitative PCR method was established to identify and quantify G. chinensis from Jinlong Capsules Formula. A standard curve for quantitative analysis of G. chinensis was established (the standard curve equation y=-3.012 7x+34.501, y is Ct value, x is lg N, N is the copies of COâ
fragment from G. chinensis). Samples included G. chinensis appeared amplification, while falsify group (not included G. chinensis) and negative control did not have amplification products. The copy number of COâ
region of G. chinensis was respectively 11.511×106, 6.416×106, 2.553×106 copies/µL in all quality goods, quality goods-adulterants 11, quality goods-adulterants 14. The results accorded with proportion of adding amount roughly. This study can provide a new strategy for quality control of Chinese patent medicine containing animal drug ingredients.
