As the core carrier of clinical Chinese medicine, the quality of traditional Chinese medicine decoction pieces directly affects the efficacy and medication safety. In recent years, with the standardized development of the traditional Chinese medicine industry,Testing of traditional Chinese medicine decoction piecesThe quality control system is constantly improving, but it still faces problems such as complex varieties, inconsistent testing standards, and weak process control. Building a comprehensive and multidimensional quality control system is the core support for ensuring the stable and reliable quality of traditional Chinese medicine decoction pieces.

Improving the testing standard system is the foundation of quality control. It is necessary to strictly follow national standards such as the Pharmacopoeia of the People's Republic of China, clarify exclusive testing indicators for different decoction pieces, covering qualitative items such as morphological identification, microscopic identification, and thin-layer chromatography identification, as well as quantitative items such as moisture, ash content, extract, and active ingredient content. For easily confused varieties such as ginseng, licorice, and roasted licorice, characteristic identification indicators should be added, and precise detection techniques such as high-performance liquid chromatography (HPLC) and gas chromatography (GC) should be used to improve identification accuracy. At the same time, based on the processing characteristics of the place of origin, personalized testing standards for authentic medicinal herbs should be developed, highlighting the unique characteristics of each variety.

Sample management is a key link in quality control. It is necessary to establish a standard for the entire process of "sampling retention sample storage", and follow the principles of randomness and representativeness when sampling, covering different batches and different parts of decoction pieces; The quantity of retained samples must meet the requirements of retesting, with clear labeling of batch, place of origin, sampling date, and other information; The storage environment should be controlled for temperature and humidity to avoid moisture, mold, or loss of active ingredients in the decoction pieces. In addition, we will implement sample traceability management and use technologies such as QR codes to associate sample information, ensuring traceability throughout the entire testing process.

Strengthening process detection and risk management is the core guarantee. In the production process of decoction pieces, key steps such as processing and processing techniques in the production area should be monitored, such as the heat of stir fried products and the amount of auxiliary materials used in baked products, to avoid quality problems caused by improper processing. During the testing process, strictly standardize experimental operations and regularly calibrate testing instruments (such as scales and chromatographs) to ensure accurate and reliable testing data. For high-risk decoction pieces (such as toxic decoction pieces and precious fine decoction pieces), special testing items for heavy metals and harmful elements, pesticide residues, microbial limits, etc. will be added to prevent quality and safety hazards.

In addition, it is necessary to strengthen the professional training of testing personnel, enhance their ability to judge the characteristics and distinguishing features of decoction pieces, and improve their experimental operation level. At the same time, we will promote innovation in detection technology by introducing rapid detection techniques such as near-infrared spectroscopy and Raman spectroscopy to improve detection efficiency. By establishing a standardized and end-to-end quality control system, the quality of traditional Chinese medicine decoction pieces can be effectively guaranteed, promoting the high-quality development of the traditional Chinese medicine industry.
