ABSTRACT

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma, this article systematically analyzes the historical evolution of the name, origin, harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica, prescription books, medical books and modern literature. The research results showed that Baiji(白及) was the main name, some scholars took Baiji(白芨) as its main name, and there were many other names such as Baiji(白给), Baigen(白根), Baiji(白苙). The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata, and drying, large, white, solid, root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials, there were certain differences between their traits, and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed, with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn, and harvested in autumn was better. The processing and processing technology is relatively simple, and it was used fresh or powdered in past dynasties, while it is mainly sliced for raw use in modern times. Based on the results, it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas, and it should be uniformly written as Baiji(白及). And if the original formula indicates the requirement of processing, it should be operated according to the requirement, if the requirement of processing is not indicated, it can be used in raw form as medicine.

ABSTRACT

As a Chinese saying goes, "good Chinese medicinal material makes good medicine", the quality of Chinese herbal medicines is related to the development prospect of Chinese medicine industry in China. With the rapid development of new technologies such as traceability methods and monitoring instruments, it is imperative to integrate and innovate traditional Chinese herbal medicines with new-generation information technology in view of the quality problems existing in the current production and circulation of Chinese herbal medicines, and it is of great significance for the construction of traceability system to ensure the quality and safety of Chinese herbal medicines and to promote the industry of Chinese herbal medicines to move towards high-quality development. This paper reviews the development history of the traceability system of Chinese herbal medicines in China, takes the influencing factors of the quality of Chinese herbal medicines as the entry point, and proposes that the construction of the traceability system should satisfy the traceability requirements of the characteristics of Chinese herbal medicines and their traditional medication experience. By analyzing the influencing factors of the quality of Chinese herbal medicines, it is pointed out that focusing on the influencing factors to build a traceability system is of great significance for targeting the problematic links at a later stage and exploring the interrelationship between environmental factors and the quality of Chinese herbal medicines. Based on the previous explorations, the author summarizes the system framework, functional modules and practical applications of the traceability system of Chinese herbal medicines, and looks forward to the development of a traceability system with risk early warning function and expert decision-making function in its functional development. Finally, based on the factors affecting the quality of Chinese herbal medicines, the author puts forward several thoughts on construction of the traceability system, and makes an in-depth analysis and puts forward a solution for the current situation that a unified, standardized and universal traceability system has not yet been built, with a view to providing ideas and references for the construction of traceability system of Chinese herbal medicines.

ABSTRACT

OBJECTIVE To evaluate the comprehensive quality of Houttuynia cordata from different producing areas. METHODS Using total flavonoids, water-soluble extract, moisture, total ash and acid-insoluble ash as indicators, the entropy weight method was used to objectively weigh each indicator, and the relative correlation degree (r)i calculated by grey correlation method was used as a measure to comprehensively evaluate the quality of H. cordata. RESULTS The weights of total flavonoids, total ash, moisture, acid-insoluble ash, and water-soluble extract were 0.295 5, 0.227 3, 0.188 7, 0.145 1, and 0.143 4, respectively. The weights of total flavonoids and total ash were relatively large. The ri of 30 batches of H. cordata ranged from 0.233 2 to 0.673 9; the average ri of samples from Quanzhou County and Ziyuan County of Guangxi Zhuang Autonomous Region were the highest, which were 0.638 3 and 0.598 7, respectively, followed by samples from Lingchuan County of Guangxi Zhuang Autonomous Region (0.556 1) and Jianshui County of Yunnan Province (0.452 8). The quality of medicinal materials produced in the above producing areas was generally good and stable. CONCLUSIONS Entropy weight method combined with the grey correlation method can be used to comprehensively evaluate the quality of H. cordata. The overall quality of H. cordata produced in Quanzhou County of Guangxi Zhuang Autonomous Region is the best.
