To clarify the key quality attributes of substance benchmarks in Danggui Buxue Decoction(DBD), this study prepared 21 batches of DBD substance benchmarks, and established two methods for detecting their fingerprints, followed by the identification of peak attribution and similarity range as well as the determination of extract and transfer rate ranges and contents of index components ferulic acid, calycosin-7-O-β-D-glucoside, and astragaloside Ⅳ. The mass fractions and transfer rates of DBD substance benchmarks from different batches were calculated as follows: ferulic acid(index component in Angelicae Sinensis Radix): 0.037%-0.084% and 31.41%-98.88%; astragaloside Ⅳ(index component in Astragali Radix): 0.021%-0.059% and 32.18%-118.57%; calycosin-7-O-β-D-glucoside: 0.002%-0.023% and 11.51%-45.65%, with the extract rate being 18.4%-36.1%. The similarity of fingerprints among 21 batches of DBD substance benchmarks was all higher than 0.9. The quality control method for DBD substance benchmarks was preliminarily established based on the HPLC fingerprint analysis and index component determination, which has provided a basis for the subsequent development of DBD and the quality control of novel related preparations.

Traditional Chinese medicine (TCM) is the treasure of the Chinese nation. As an important raw material for clinical treatment of diseases, Chinese materia medica plays an extremely important role. However, in the process of transformation from traditional wild collection of animals and plants to modern artificial cultivation and industrial production of preparations, whether the quality of Chinese materia medica is fully transferred will directly affect the quality and clinical efficacy of Chinese materia medica preparation. From the field to the sickbed, process control of quality transfer of Chinese materia medica is the key to guarantee quality and curative effect. In this paper, the whole process that affects the quality of Chinese materia medica preparations such as seed and seedling, planting and breeding, harvesting and processing, processing of decoction pieces and preparation production was analyzed. Paying attention to the whole process of quality control of Chinese materia medica is of great significance to improve the quality of Chinese materia medica preparations and promote the rapid development of TCM. Based on this, the author intended to analyze the key control links in the quality transfer process of Chinese materia medica (breeding, planting areas and field management, timely harvesting and intensive primary processing, appropriate processing, optimization of preparation technology, standardization of packaging and informationization of storage and transportation), in order to provide reference for the design and development of Chinese materia medica preparations guided by clinical value.
