Embodiment 1
[0059] Identification of bone components in Sailong in Example 1 Zaizao Pill (Sailong Fang)
[0060] 1. Extraction of total DNA from Theron bone
[0061]This extraction step can be performed according to conventional operations in the field. The specific operations of the present embodiment are as follows: the Sialon bone is ground into small pieces with a mortar, and can be used for DNA extraction after 48 hours of EDTA decalcification (10% EDTA solution (pH7.0). 200 μg sample (Sialon after decalcification) Bone, initial weight) was added to 1ml lysate A (10mM Tris-HCl pH8.0, 0.1MEDTA pH8.0, 0.5% SDS, 200μg / ml proteinase K), and digested overnight at 55°C. The digested sample was centrifuged at 12000rpm for 15min to take the supernatant Carry out phenolic extraction. Then use 2 times of volume dehydrated alcohol precipitation DNA, then wash precipitation twice with 75% ethanol, appropriate 50 μ l double-distilled water dissolves. Sample DNA is through PCR purification kit (K...
Embodiment 2
[0094] Example 2 Identification of Theron Bone Components in Sailong Fengshi Capsules
[0095] Select 3 batches (10 capsules / batch) of Silong Fengshi Capsules finished medicine (a total of one medicine) as the samples to be tested, take 4g of the capsule content for each sample, extract DNA, and use the primers to pair SEQ ID Nos. .1 and 2, SEQ ID Nos.3 and 4, and SEQ ID Nos.5 and 6 were subjected to single-plex PCR amplification, respectively.
[0096] see results Image 6 (Take the experimental results of one sample as an example, and the rest are the same). The Theron species-specific primer can amplify the target fragment from the corresponding finished drug.
[0097] Image 6 Among them, swimming lane 1 represents the detection result taking reconstituted pill (Leopard bone prescription) as the test sample; Swimming lane 2 represents the detection result taking Sailong Fengshi Capsule (Leopard bone prescription) as the test sample; Swimming lane 3 represents the reconst...
