Pills are spherical or quasi spherical solid preparations made of fine powder or extract of medicinal materials plus appropriate adhesives or excipients, and are one of the ancient dosage forms of traditional Chinese patent medicines and simple preparations. The DNA detection scheme of PCR is becoming the gold standard for the authenticity identification of traditional Chinese medicine, but the complex composition of processed Chinese medicine pills, including adhesives and excipients, has an inhibitory effect on the PCR reaction, resulting in ineffective use of DNA detection methods in this field. This kit achieves effective DNA extraction purity by using a self-developed DNA extraction method to effectively clean some PCR inhibitory components. The extracted DNA can be directly used for PCR reactions, providing a reliable detection scheme for the authenticity identification and adulteration detection of medicinal materials.
