Identification of Scolopendra Dispensing Granules by Allele-specific PCR增强出版
To establish an allele-specific polymerase chain reaction (PCR) method for identifying Scolopendra dispensing granules, so as to ensure the quality and therapeutic effects of Scolopendra and its preparations.
Method
2
The primer interval suitable for the PCR was selected based on the cytochrome c oxidase subunit 3(COX-3) gene sequence of Scolopendra, and the single nucleotide polymorphism (SNP) loci of Scolopendra
and its adulterants were mined from the interval for the design of specific primers. The samples of Scolopendra and its adulterants were collected. The PCR system was established and optimized regarding the annealing temperature, cycles,
Taq
enzymes, DNA template amount, PCR instruments, and primer concentrations, and the specificity and applicability of this method were evaluated.
Result
2
The PCR system was composed of 12.5 μL 2×M5 PCR Mix, 0.4 μL forward primer (10 μmol·L
-1
), 0.4 μL reverse primer (10 μmol·L
-1
), 2.5 μL DNA template, and 9.2 μL sterile double distilled water. PCR parameters: Pre-denaturation at 94 ℃ for 3 min, 30 cycles (94 ℃ for 20 s, 62 ℃ for 20 s, 72 ℃ for 45 s), and extension at 72 ℃ for 5 min. After PCR amplification with the system and parameters above, the electrophoresis revealed a bright band at about 135 bp for Scolopendra and no band for the adulterants.
Conclusion
2
The established allele-specific PCR method can accurately identify the medicinal materials, decoction pieces, and standard decoction freeze-dried powder of Scolopendra, as well as the intermediates and final products of Scolopendra dispensing granules, which is of great significance for ensuring the quality and clinical efficacy of Scolopendra and its preparations.
