Embodiment 1
[0050] Example 1 Using the PCR-RFLP technology included in the Chinese Pharmacopoeia to identify the bases of Fritillaria sichuan, Fritillaria gansu, Fritillaria oleifera, Fritillaria wabu, Fritillaria saxa, and Fritillaria taibai
[0051] Step 1) Extraction of Genomic DNA
[0052] Six batches of each Fritillaria were taken, and the DNA was extracted using a DNA extraction kit.
[0053] ① Wash the samples with sterilized water, 75% ethanol and double distilled water in sequence, and place them on a clean bench to dry. After drying, grind it to a very fine powder with a mortar in an ultra-clean workbench, accurately weigh 0.1g of the sample powder, and transfer it to another mortar; Put the liquid into a 1.5mL centrifuge tube, and make up to 350μL with PBS buffer; ③Add 150μL Buffer C-L and mix well, then add 20μL Proteinase K, mix well, place in a 56℃ water bath for 30min, and mix up and down every 5min; ④Add 350μL Buffer P-D, mix well and centrifuge at 12000rpm for 10min; ⑤T...

[0067] Example 2 Utilizing the method described in the present invention, primer 1 is used to identify the original Fritillaria sichuanensis - Fritillaria sichuanensis, Fritillaria gansuensis, Fritillaria brunica, Fritillaria wabu, Fritillaria saxabilis and Fritillaria taibai
[0068] Step 1) Extraction of Genomic DNA
[0069] Six batches of each Fritillaria were taken, and the DNA was extracted using a DNA extraction kit.
[0070] According to the method of step 1) of Example 1, the genomic DNAs of Fritillaria sichuan, Fritillaria gansu, Fritillaria dark purple, Fritillaria wabu, Fritillaria sativa and Fritillaria taibai samples were extracted.
[0071] Step 2) PCR amplification
[0072] According to the method in step 2) of Example 1, the genomic DNA extracted in step 1) was used as a template, and PCR amplification was performed using primer 1.
[0073] Primer 1:
[0074] Upstream primer: 5'ACTATGCCCGCCCTACC 3',
[0075] Downstream primer: 5'GCTACGTTTCTTCATCGAT 3'.

[0079] Example 3 Utilizing the method described in the present invention, primer 2 is used to identify the original Fritillaria sichuanensis - Fritillaria sichuanensis, Fritillaria gansuensis, Fritillaria nigra, Fritillaria wabu, Fritillaria saxabilis and Fritillaria taibai
[0080] Step 1) Extraction of Genomic DNA
[0081] Six batches of each Fritillaria were taken, and the DNA was extracted using a DNA extraction kit.
[0082] According to the method of step 1) of Example 1, the genomic DNAs of Fritillaria sichuan, Fritillaria gansu, Fritillaria dark purple, Fritillaria wabu, Fritillaria sativa and Fritillaria taibai samples were extracted.
[0083] Step 2) PCR amplification
[0084] According to the method in step 2) of Example 1, the genomic DNA extracted in step 1) was used as a template, and PCR amplification was performed using primer 2.
[0085] Primer 2:
