ABSTRACT

Chinese medicine dispensing granules, the result of the efforts to transform Chinese medicinal decoction pieces in China, features portability and ease of storage. Thus, it is destined to be an indispensible dosage form in the modernization drive of Chinese medicine. The Announcement on Ending the Pilot Project of Chinese Medicine Dispensing Granules was released in February 2021 and relevant regulations went into force in November 2021, which marks the a new journey for the development of Chinese medicine dispensing granules and the beginning of the "post-pilot era". However, it faces the challenges in quality and standard. This study reviewed the history of Chinese medicine dispensing granules, analyzed the technical progress, market, and main problems in development, and proposed suggestions and prospects for its development in the "post-pilot era", which is expected to serve as a reference for its industry development and rational use.

ABSTRACT

Objective:To establish a new fast and accurate method for identifying the authenticity and specifications of Fritillariae Cirrhosae Bulbus based on electronic nose technology, and to discuss the feasibility of this technology in the identification of decoction pieces. Method:Fritillariae Cirrhosae Bulbus was used as the research object, 80 batches of samples to be tested were collected, and the olfactory sensory data of the electronic nose were taken as independent variables (<italic>X</italic>), the results of the method contained in the 2020 edition of <italic>Chinese Pharmacopoeia</italic> were taken as the focus, and the traditional empirical identification results were used as benchmarking information (<italic>Y</italic>). Four chemometric methods, including discriminant analysis (DA), least square support vector machine (LS-SVM), principal component analysis-DA (PCA-DA) and partial least squares-DA (PLS-DA), were used to establish the identification model [<italic>Y</italic>=<italic>F</italic>(<italic>X</italic>)] of authenticity and commodity specifications of Fritillariae Cirrhosae Bulbus, respectively. Wherein, the identification accuracy and time-consuming was taken as indicators to discuss the results. Result:After cross-verification by leave-one-out method, the correct rates of the above four models were 93.75%, 91.25%, 95.00% and 95.00%, respectively, and the PCA-DA and PLS-DA identification models were the best in terms of authenticity identification. In specification identification, the correct rates of these four models were 86.67%, 88.00%, 89.33% and 68.00%, respectively, and the PCA-DA identification model was the best. The electronic nose had a high accuracy in the identification of authenticity and specification model, and the time consuming was relatively short. Conclusion:Electronic nose technology can identify Fritillariae Cirrhosae Bulbus accurately and quickly, and has significant advantages in terms of timeliness and correct judgment rate.
